Answer:

Yes the equation is balanced

Explanation:

There is 2Na and 2F on both sides which means LHS=RHS. Hence,its balanced.

The empirical formula of at least four binary ionic compounds that could be formed from the calcium, chromium, chloride and sulfide ions are CaCl₂, CrCl₄, NaCl and CaS respectively.

If any compound which is composed of two different elements, one of which is a positive ion (metal), and the other is negative ion (non-metal) is called binary ionic compounds.

Hence, CaCl₂, CrCl₄, NaCl and CaS are the four binary ionic compounds.

The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.

A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.

This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.

Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

Answer:

saturated is the correct one

Answer: saturated

Explanation:

When a solution contains the maximum amount of solute that can dissolve under a given set of conditions, it is a saturated solution. Any more solute added will sit as crystals on the bottom of the container.

Answer:

v1=35,679.7 ml

Explanation:

p1v1/t1=p2v2/t2

v1=t1p2v2/p1t2

v1=672.44*442.6*7650ml/267.86*239.18

v1=35,679.7 ml

Molality is the ratio of the moles of the solute and the mass of the solvent. The molality of the solute is 7.38 m.

Molality is the moles of the solute present in a kilogram of the solvent in a solution of the substance.

Given,

Percent by mass = 25.5 %

In 100 gm of solution = 25.5 gm of  formic acid

Mass of solution = 100 gm

Mass of solute = 25.5 gm

Mass of solvent = 74.5 gm

Moles of solute are calculated as:

[tex]\dfrac{25.5}{46} = 0.55 \;\rm moles[/tex]

Moles of solvent are calculated as:

[tex]\dfrac{74.5}{18} = 4.13\;\rm moles[/tex]

Molality is calculated as:

[tex]\begin{aligned} \rm Molality &= \rm \dfrac{moles}{\text{mass in kg}}\\\\&= \dfrac{0.55}{0.0745}\\\\&= 7.38 \;\rm m\end{aligned}[/tex]

Therefore, 7.38 m is the molality of the solute.

if pressure is increased, equilibrium will shift toward the side that has the last amount of moles in order to alleviate the sudden change and bring the pressure back down.

The pressure of hydrogen gas formed  is 720.8 mmHg.

The pressure exerted by a (specified) component in a mixture of gases.

We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.

This means that the total pressure of the mixture will have two components.

The vapor pressure of water at that temperature is approximately

19.231 mmHg.

This means that

[tex]\rm P_{total} = P_{hydrogen} + \; P_{water vapor}[/tex]

740 = [tex]\rm P_{hydrogen}[/tex] + 19.231

[tex]\rm P_{hydrogen}[/tex] = 740-19.231

[tex]\rm P_{hydrogen}[/tex] = 720.8 mmHg

Therefore the pressure of hydrogen gas formed  is 720.8 mmHg.

Answer:

206.99 C

Explanation:

V1 / T1   = V2 / T2             T must be in K units

V1 * T2/V2 = T1

255 C =   528.15 K

(1)(528.15)/1.1 = T1 = 480.14 K    = 206.99 C

Answer:

1CO + 2H₂ —> 1CH3OH

Explanation:

When balancing any chemical equation given, you identify the amount of reactants and amount of products.

From our given equation;

__CO +__ H₂ —> __CH3OH

Reactants

C = 1

O = 1

H = 2

Products

C = 1

O = 1

H = 3 + 1 = 4

This shows that Hydrogen is not balanced we require 2 to balance it. Thus giving us;

1CO + 2H₂ —> 1CH3OH,

Which is balanced.

The mass of the sample of the material is 0.1664 g.

The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

By the formula of specific heat

[tex]Q = mc \Delta T[/tex]

Given, that the specific heat (c) of material is 0.416 J/gC

The difference in temperatures is 30°C to 50°C

The mass=?

Q = heat, 50 J

Putting the values in the equation

[tex]\rm 50\;J = m \times 0.416 J/g^\circ C \times (50 - 30)\\\\m = \dfrac{0.416 J/g^\circ C \times 20}{50} = 0.1664 g[/tex]

4.14 x 10²⁴ molecules CO₂

Explanation:

2 C₄H₁₀ + 13 O₂ --> 8 CO₂ + 10 H₂O

To find the number of CO₂ molecules, you need to start with 100 grams of butane (C₄H₁₀), convert to moles (using the molar mass), convert to moles of CO₂ (using coefficients from equation), then convert to molecules (using Avagadro's number). The molar mass of C₄H₁₀ is calculated using the quantity of each element (subscript) multiplied by the number on the periodic table. The ratios should be arranged in a way that allows for units to be cancelled.

4(12.011g/mol) + 10(1.008 g/mol) = 58.124 g/mol C₄H₁₀

100 grams C₄H₁₀          1 mol C₄H₁₀             8 mol CO₂

The given reaction is [tex]\rm N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)[/tex]

By the stoichiometry rule of ratio hydrogen: nitrogen

3 : 1

The reacted moles of nitrogen is equals to H/3 moles of reacted hydrogen
