Chemistry question. Image attached.
Stells [14]

Answer:

The answer to your question is given below

Explanation:

The balanced equation for the reaction is given below:

CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)

1. Writing an expression for the equilibrium constant, K.

The equilibrium constant, K for a reaction is simply the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.

Thus, we can write the equilibrium constant, K for the reaction as follow:

CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)

K = [CaCO3] [H2]⁴ / [CaO] [CH4] [H2O]²

2. Based on the value of K, more products will be in the equilibrium mixture since the value of K is a positive large number.

Calculate the volume of an object (in mL) if the density of the object is 4.08 g/mL and the mass of the object is 10.02 g.
slega [8]

Answer:

<h2>The answer is 2.5 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of object = 10.02 g

density = 4.08 g/mL

The volume of the object is

volume =  \frac{10.02}{4.08}  \\  = 2.4558823...

We have the final answer as

<h3>2.5 mL to one decimal place</h3>

Hope this helps you

What are the coefficients of the compounds after balancing the following equation and what type of reaction is this?
Oksana_A [137]

The coefficient of Fe would be 2, the coefficient of Cl2 would be 3, while the coefficient of FeCl2 would be 2.  

The balanced equation of the reaction would be as follows:

2Fe(S) + 3Cl_2 ---> 2FeCl_3(S)

Thus, the coefficients of Fe, Cl2, and FeCl3 respectively would be 2, 3, and 2.

In other words, 2 moles of Fe require 3 moles of Cl2 to produce 2 moles of FeCl3 in a complete reaction.
