Answer:True
Explanation:
A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.
Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.
Lets take A be the solute and B be the solvent so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).
The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.
The enthalpy of mixing and volume of mixing of ideal solution is zero.
enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case of ideal solutions it is zero.
Volume of mixing is change in volume on mixing a solute and solvent.
<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.
The base gram of the compound is 16.042
To find the new amount of grams, you need to multiply the amount of moles by the the base grams
16.042*.25=4.01
So one fourth of the compound is 4.01 grams of Carbon tetrahydride.
Answer: 20 g
Explanation: heat received Q = m c dT
Q= 50J , dT= 25 C anc c= 0.10 J / g C
And m = Q / c dT
