<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.
Answer: A heterogeneous mixture is a mixture in which its components retain their identity.
Why: Heterogeneous mixtures have several parts which can't be separated, like an italian dressing. Therefore, it's prefix is (hetero), which means something along the lines of "different". In a homogeneous mixture, it can be separated, and the prefix (homo) means "same".
The atomic number of an element gives the element it's identity. This is also known as the number of protons within an element. If you have the number of protons but don't know the element's atomic mass, add the protons and neutrons to get the mass number.

Answer:
The answer is
<h2>0.24 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
From the question
mass of cork = 2.88 g
volume = 12 mL
The density is

We have the final answer as
0.24 g/mL
Hope this helps you
Answer:
b. 1.5 atm.
Explanation:
Hello!
In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:

Now, if we introduce the stoichiometry, and the change in the pressure
we can write:

Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:

Thus, the final pressure is:

Therefore the answer is b. 1.5 atm.
