Answer:

C. Iron combines with oxygen to form rust.

Explanation:

The correct answer is "C" because it refers to the ability to rust, a chemical property, because rusting is a chemical change.

Answer choice "A" is incorrect because it refers to malleability, the ability to be flattened or pressed into sheets, a physical property. After being flattened, the iron would have gone through a physical change, not chemical.

Answer choice "B" is incorrect because it refers to conductivity, the ability to conduct electricity and heat, a physical property. The iron does not experience a chemical change while conducting.

Answer choice "D" is incorrect because it refers to ductility, the ability to be made into wire, a physical property. The iron is not going through a chemical change as wire.

At equilibrium at 2500K, [HCl]=0.0625M and [H2]=[Cl2]=0.00450M for the reaction H2+Cl2 ⇌ HCl.
ASHA 777 [7]

Answer:

a. H_2+Cl_2 \rightleftharpoons 2HCl

b. K = 192.9

c. Products are favored.

Explanation:

Hello!

a. In this case, according to the unbalanced chemical reaction we need to balance HCl as shown below:

H_2+Cl_2 \rightleftharpoons 2HCl

In order to reach 2 hydrogen and chlorine atoms at both sides.

b. Here, given the concentrations at equilibrium and the following equilibrium expression, we have:

K=\frac{[HCl]^2}{[H_2][Cl_2]}

Therefore, we plug in the data to obtain:

K=\frac{(0.0625)^2}{(0.00450)(0.00450)}\\\\K=192.9

c. Finally, we infer that since K>>1 the forward reaction towards products is favored.

Best regards!
