The final velocity of two cars that stick together after a collision is 18.5 m/s. The change in kinetic energy of the system is 322,505 J, and an inelastic collision occurred.

To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a closed system remains constant if no external forces act on it.

First, we calculate the initial momentum of the system:

p_initial = m1 * v1 + m2 * v2

p_initial = 1250 kg * 20.0 m/s + 1610 kg * 8.0 m/s

p_initial = 40,000 kg m/s + 12,880 kg m/s

p_initial = 52,880 kg m/s

Next, we calculate the total mass of the system after the collision:

m_total = m1 + m2

m_total = 1250 kg + 1610 kg

m_total = 2860 kg

Since the two cars stick together after the collision, we can assume that they move as one object. Therefore, the final velocity of the two cars can be calculated as follows:

v_final = p_initial / m_total

v_final = 52,880 kg m/s / 2860 kg

v_final = 18.5 m/s

To calculate the change in kinetic energy of the system, we can use the formula:

ΔK = K_final - K_initial

The initial kinetic energy of the system can be calculated as:

K_initial = 1/2 * m1 * v1² + 1/2 * m2 * v2²

K_initial = 1/2 * 1250 kg * (20.0 m/s)² + 1/2 * 1610 kg * (8.0 m/s)²

K_initial = 400,000 J + 51,520 J

K_initial = 451,520 J

The final kinetic energy of the system can be calculated as:

K_final = 1/2 * m_total * v_final²

K_final = 1/2 * 2860 kg * (18.5 m/s)²

K_final = 774,025 J

Therefore, the change in kinetic energy of the system is:

ΔK = K_final - K_initial

ΔK = 774,025 J - 451,520 J

ΔK = 322,505 J

Since the total kinetic energy of the system is not conserved, and some of it is converted to other forms of energy such as heat and sound, we can conclude that an inelastic collision occurred in the system.

39.4 mL of 0.586 M Ba(OH)2 solution is required to neutralize 10 mL of vinegar containing 2.78 g of acetic acid.

The balanced chemical equation for the reaction between barium hydroxide and acetic acid is:

Ba(OH)2(aq) + 2CH3COOH(aq) ⟶ Ba(CH3COO)2(aq) + 2H2O(l)

The molar mass of acetic acid (CH3COOH) is 60.05 g/mol.

First, we need to determine the moles of acetic acid present in 10 mL of vinegar:

molar mass of acetic acid = 60.05 g/mol

mass of acetic acid in 10 mL of vinegar = 2.78 g

moles of acetic acid = mass/molar mass = 2.78 g / 60.05 g/mol = 0.0463 mol

From the balanced chemical equation, we see that 1 mole of Ba(OH)2 reacts with 2 moles of CH3COOH. Therefore, the moles of Ba(OH)2 required to react with 0.0463 mol of CH3COOH is:

moles of Ba(OH)2 = (0.0463 mol CH3COOH) / 2 = 0.0231 mol Ba(OH)2

Now, we can use the definition of molarity to find the volume of 0.586 M Ba(OH)2 solution needed to provide 0.0231 mol Ba(OH)2:

Molarity = moles of solute / volume of solution in liters

volume of solution in liters = moles of solute / Molarity

volume of Ba(OH)2 solution needed = 0.0231 mol / 0.586 mol/L = 0.0394 L

Finally, we convert the volume of Ba(OH)2 solution from liters to milliliters:

volume of Ba(OH)2 solution needed = 0.0394 L * (1000 mL/L) = 39.4 mL

Therefore, 39.4 mL of 0.586 M Ba(OH)2 solution is required to neutralize 10 mL of vinegar containing 2.78 g of acetic acid.

To solve the problem, we can use the formula,

Q = m * c * ΔT , amount of heat absorbed by the wood is Q, its mass is m, specific heat capacity is c, the change in temperature is ΔT.

We know that m = 1500.0 g, c = 1.8 J/gºC, Q = 67,500 J, and the final temperature T₂ = 57ºC. We need to find the initial temperature T₁.

The partial pressure of ethane and propane in the flask are both 16.42 atm.

The given information tells us that the flask is sealed, which means that no gas can enter or leave the flask. It also tells us that the volume of the flask is 10.0L and the temperature is 400K. Finally, it tells us that there are equimolar amounts of ethane and propane in the flask.

From this information, we can assume that the total pressure inside the flask is the sum of the partial pressures of ethane and propane. This is because the ideal gas law tells us that PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is the temperature. Since the number of moles of each gas is the same, we can assume that their partial pressures are equal.

To find the partial pressures, we need to use the ideal gas law again. However, we need to know the total number of moles of gas in the flask. We can find this by using the fact that the amounts of ethane and propane are equimolar. Since the molar mass of ethane is 30 g/mol and the molar mass of propane is 44 g/mol, we know that the total mass of gas in the flask is 74 g. Dividing this by the sum of the molar masses (30+44=74 g/mol), we get the total number of moles, which is 1 mol.

Now we can use the ideal gas law to find the partial pressures. We'll use R = 0.08206 L·atm/(mol·K) as the gas constant. For ethane, we have:

PV = nRT
P_ethane * 10.0L = 0.5 mol * 0.08206 L·atm/(mol·K) * 400K
P_ethane = (0.5 mol * 0.08206 L·atm/(mol·K) * 400K) / 10.0L
P_ethane = 16.42 atm

For propane, we get the same result:

PV = nRT
P_propane * 10.0L = 0.5 mol * 0.08206 L·atm/(mol·K) * 400K
P_propane = (0.5 mol * 0.08206 L·atm/(mol·K) * 400K) / 10.0L
P_propane = 16.42 atm

The ions arranged in terms of increasing atomic radius from left to right are: Ca²⁺, Sr²⁺, Na⁺, K⁺, Rb⁺.

As we move from left to right across the periodic table, due to the increasing nuclear charge the number of protons in the nucleus increases, pulling the electrons closer to the center and decreasing the atomic radius. However, as you move down a group, the number of electron shells increases, which increases the distance between the nucleus and outermost electrons, increasing the atomic radius.

Cations (positively charged ions) have smaller radii than their corresponding neutral atoms due to the loss of electrons and increased effective nuclear charge. Ca²⁺, Sr²⁺ have a +2 charge and; K⁺, Rb⁺, and Na⁺ have a +1 charge. Higher charge leads to a smaller atomic radius.

Ca²⁺, Sr²⁺  are located in Group 2, while K⁺, Rb⁺, and Na⁺ are located in Group 1 of periodic table. Arrange the ions based on their positions in the periodic table and their charges.

Based on these factors, the correct order of ions in terms of increasing atomic radius is: Ca²⁺ (smallest), Sr²⁺, Na⁺, K⁺, and Rb⁺ (largest).

From the calculations, we can see that the mass of the acetic acid that is produced is 28.2 g.

In a chemical reaction involving two or more reactants, the limiting reactant is the reactant that is consumed completely, thereby limiting the amount of product that can be formed. The other reactant(s) that remain after the limiting reactant is completely consumed are called excess reactants.

Number of moles of CH3CHO = 20.8g/44 g/mol

= 0.47 moles

Number of moles of O2 = 14.5 g/32 g/mol

= 0.45 moles

If 2 moles of CH3CHO reacts with 1 mole of O2

0.47 moles of CH3CHO would react with 0.47 * 1/2

The number of moles in the room depends on the temperature.

Assuming that the temperature and volume in the room are the same as those outside, we can use the ideal gas law to calculate the number of moles of gas in the room.

Ideal gas law is given by:

PV = nRT

Number of moles:

n = PV/RT

Since the temperature and pressure are the same in both cases, we can write:

n(room) = (P × V(room)) / RT

n(bulb) = (P × V(bulb)) / RT

We are given that the bulb contains 9.00 moles of gas at the same temperature and pressure as the room. Therefore, we can use the number of moles in the bulb to find the pressure and temperature:

n(bulb) = (P × V(bulb)) / RT

9.00 mol = (P × 61.0 L) / (R × T)

Similarly, for the room, we can write:

n(room) = (P × V(room)) / RT

n(room) = (P × 85.0 L) / (R × T)

P = (n × RT) / V

P = (PV / RT) × RT / V

P = nRT / V

We can use the value of n from the bulb to find the pressure and temperature:

9.00 mol × R × T / 61.0 L = P

P = 3.17 atm

Now we can use this value of pressure to find the number of moles in the room:

n(room) = (P × V(room)) / RT

n(room) = (3.17 atm × 85.0 L) / (R × T)

n(room) = (3.17 atm × 85.0 L) / (0.08206 L atm/mol K × T)

n(room) = 129.3 L atm / (R × T)

Therefore, the number of moles in the room depends on the temperature.

To find the empirical formula of the titanium chloride, we need to use the given information to determine the moles of titanium and chlorine in the original compound, and then use those values to find the simplest whole-number ratio of atoms in the empirical formula.

First, we can find the moles of titanium in the original compound using the mass of the titanium metal produced:

mass of titanium metal = 0.819 g

molar mass of titanium = 47.867 g/mol

moles of titanium = mass of titanium metal / molar mass of titanium

moles of titanium = 0.819 g / 47.867 g/mol

moles of titanium = 0.0171 mol

Next, we can use the law of conservation of mass to find the moles of chlorine in the original compound:

moles of chlorine = moles of titanium

Now we can find the mass of chlorine in the original compound using the moles of chlorine and the molar mass of chlorine:

moles of chlorine = 0.0171 mol

molar mass of chlorine = 35.453 g/mol

mass of chlorine = moles of chlorine x molar mass of chlorine

mass of chlorine = 0.0171 mol x 35.453 g/mol

mass of chlorine = 0.606 g

Finally, we can use the masses of titanium and chlorine to find the empirical formula of the titanium chloride. The empirical formula gives the simplest whole-number ratio of atoms in a compound, so we need to divide the masses of each element by their respective atomic masses to get the number of moles of each element:

moles of titanium = 0.0171 mol

moles of chlorine = 0.606 g / 35.453 g/mol = 0.0171 mol

There are 3530.88 grams of sulfuric acid (H₂SO₄) dissolved in a 2-liter solution that is 18 molar.

To calculate the grams of sulfuric acid (H₂SO₄) dissolved in a 2-liter solution that is 18 M (molar), you can follow these steps:

1. Determine the moles of H₂SO₄ in the solution:
Moles of H₂SO₄ = Molarity × Volume of solution
Moles of H₂SO₄ = 18 M × 2 L = 36 moles

2. Calculate the grams of H₂SO₄ using the molar mass:
Grams of H₂SO₄ = Moles × Molar mass of H₂SO₄
The molar mass of H₂SO₄ = (2 × H) + (1 × S) + (4 × O) = (2 × 1.01) + (32.07) + (4 × 16.00) = 98.08 g/mol

3. Multiply the moles of H₂SO₄ by its molar mass:
Grams of H₂SO₄ = 36 moles × 98.08 g/mol = 3530.88 grams

So, 3530.88 grams of sulfuric acid (H₂SO₄) are dissolved in a 2-liter solution that is 18 molar.

The rate of the reaction will increase because the concentration of the reactants increases.

When the volume of a reaction vessel with gaseous reactants is reduced to one-fourth of its original volume, the gaseous particles are brought closer together. This results in an increased concentration of the reactants, as there are more particles in a smaller space.

Higher concentrations of reactants lead to a greater likelihood of successful collisions between reactant particles, which in turn leads to an increased rate of the reaction.

So, by decreasing the volume and increasing the concentration of reactants, you effectively speed up the reaction rate.
