Explanation:

Hello there!

In this case, according to the given by-mass percent of HCl, which can be set up in terms of mass of HCl over mass of solution, we can calculate the molarity, by multiplying by the density to get the mL's of solution and further convert to liters. Moreover, the molar mass of HCl (36.46 g/mol) must be also used to calculate the moles, since molar units requires moles of solute and liters of solution as shown below:

[tex]M=\frac{37.0gHCl}{100g\ sln}*\frac{1.18g\ sln}{1mL\ sln}*\frac{1000mL\ sln}{1L \ sln}*\frac{1molHCl}{36.46gHCl}\\\\M= 12.0M[/tex]

The scientific method is an empirical method of acquiring knowledge.

These are the 5 scientific methods:

Solution :

Assuming all Al will be consumed in the reaction.

From the given equation, 2 mole of Al produce 2 mole of [tex]Na_3AlO_3[/tex].

So, 1 mole of Al produce 1 mole of  [tex]Na_3AlO_3[/tex].     .....statement 1)

Number of moles of Al in 258 gram of Al.

[tex]n = \dfrac{mass}{molar\ mass}\\\\n = \dfrac{258}{27}\ moles\\\\n = 9.556 \ moles[/tex]

Therefore, from statement 1) number of moles of [tex]Na_3AlO_3[/tex] produced is also 9.556 moles.

Answer:

1, you should use candles for experiments because, You created an area of low pressure! When the experiment is run you can see tiny bubbles escaping under the glass which shows that the increased air pressure from the heated air as the candle burns. Once the candle runs out of oxygen, the candle burns out and the remaining air inside cools down.

2. you should put candles on sand trays, Pour layers of sand into a glass vase, alternating colors with each layer. For a more interesting look, try uneven layers in various heights. Keep layering sand until you're a few inches from the top of the vase. Place your votive candle in the center of the sand.

Answer:

279.225g

Explanation:

Answer:

T(initial) = 241.4˚C

Explanation:

∑q = q(metal) + q(water) = 0*

Q(metal) = (m∙c∙ΔT)Fe = 360g x 0.444j/g˚C x (45.7˚C – T(initial)) = 159.84j/˚C(45.7˚C – T(initial)) = 7304.69 j – 159.84j/˚C x T(initial)

Q(water) =  (m∙c∙ΔT)water = 425g x 4.184j/g˚C x (45.7˚C - 24˚C) = 38,586.94 joules

∑[Q(metal) + Q(water)] = 7304.69j -159.84j/˚C x T(initial) + 38586.94j  = 0

=> 159.84 x T(initial)j/˚C = 38586.94j  

=> T(initial) = 38586.94j / 159.84j/˚C  = 241.4˚C

____________________________________

*Initial equation is from Heat Loss = Heat Gained  (Conservation of Energy) That is, Heat lost + (- Heat gained) = 0

=> ∑(heat loss by metal) + (- heat gained by water) = 0

using heat transfer equation with temperature change

=> mcΔT(metal) + (-mcΔT(water) = mcΔT(metal) - (mcΔT(water) = 0

Answer:

0.0300 moles of H₂

Explanation:

The original equation is PV = nRT. We need to change this to show moles (n).

n = [tex]\frac{PV}{RT}[/tex]

It's important to convert your values to match the constant (r) in terms of units.

30.0 kPa = 0.296 atm

2500 mL = 2.50 L

27 °C = 300 K

Now, plug those values in to solve:

n = [tex]\frac{(0.296)(2.50)}{(0.0821)(300)}[/tex]    -  for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)

Finally, you are left with n = 0.0300 moles of H₂

Answer:

the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2

Explanation:

a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below

As we know that

Pressure = F ÷ area

Also

F = mg

Now

= (1500 × 9.8) ÷π (0.24)^2

= 81,726 N/m^2

Hence, the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2

Answer:

A) An ionic compound dissolved in a polar solvent

Explanation:

Potassium Chloride's chemical formula is KCl. Most ionic compounds are formed between a nonmetal and a metal. In this case, potassium is acting as the metal and chloride is the nonmetal. Water is a polar solvent due to the electronegativity of the oxygen in the molecule creating a partial negative pole, leaving the hydrogen atoms partially positive. Hence, A is your best answer.

Answer:

A. 6 moles

Explanation:

This question contains a chemical reaction between aluminum (Al) and Copper(II)Chloride to give copper and aluminum chloride. The unbalanced chemical equation is as follows:

Al (s) + 3CuCl2 (aq) → Cu (s) + 2AlCl3

To balance the equation, we use coefficients in front of Al and Cu to ensure the amount of both are uniform on both sides of the equation. The balanced equation is as follows;

2Al (s) + 3CuCl2 (aq) → 3Cu (s) + 2AlCl3

From the balanced equation, 2 moles of Al reacts with 3 moles of CuCl2

Hence, 4 moles of Al will react with (4 × 3) ÷ 2

= 12 ÷ 2

= 6 moles of CuCl2

Answer: The volume occupied by He is 62.4 L

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 0.980 atm

V = Volume of gas = ?

n = number of moles = 2.50 mol

R = gas constant =

T =temperature =[tex]25.0^0C=(25.0+273)K=298.0K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{2.50mol\times 0.0821 Latm/K mol\times 298.0K}{0.980atm}=62.4L[/tex]

Thus the volume occupied by He is 62.4 L

Answer:

[tex]T_2=98.5^{\circ}[/tex]

Explanation:

Given that,

The specific heat of water is 4.184Jg°C

Mass, m = 600 g

Initial temperature, T₁ = 75.5°C

We need to find the final temperature. We know that heat absorbed is given by :

[tex]Q=mc\Delta T\\\\Q=mc(T_2-T_1)\\\\\dfrac{Q}{mc}=(T_2-T_1)\\\\\\T_2=\dfrac{Q}{mc}+T_1\\\\T_2=\dfrac{5.9\times 10^4}{600\times 4.184}+75\\\\T_2=98.5^{\circ}[/tex]

So, the final temperature is equal to [tex]98.5^{\circ}[/tex].
