<u>Answer:</u> The net chemical equation for the production of acrylic acid is given below.
<u>Explanation:</u>
We are given two intermediate equations:
<u>Equation 1:</u> 
<u>Equation 2:</u> 
To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.
The equation becomes:
<u>Equation 1:</u> 
<u>Equation 2:</u> 
Net chemical equation now becomes:

Hence, the net chemical equation for the production of acrylic acid is given above.
It is a chemical change

molar concentration of AgNO₃ solution = 0.118 mole/L
Explanation:
Because we have the volume of the solution and there is no information about the density of the solution I will asume that you ask for the molar concentration.
number of moles = mass / molecular weight
number of moles of AgNO₃ = 10 / 170 = 0.0588
molar concentration = number of moles / volume (L)
molar concentration of AgNO₃ solution = 0.0588 / 0.5
molar concentration of AgNO₃ solution = 0.118 mole/L
