Answer:
Explanation:
Synthesis is the combining of two elements or atoms into a compound/mixture. Decomposition is the breaking down of a compound/mixture into individual atoms or elements. In conclusion, on is the building up of a compund/mixture and one is breaking down.

Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
Density = mass divided by volume. 15/30 is 1/2 so the density is 1/2 or 0.5 g/cm
Answer:
The coefficient of thermal expansion α is

The coefficient of compressibility

Now considering 
From equation (1) we have that

From ideal equation

So

=> 
=> 
Explanation:
From the question we are told that
The coefficient of thermal expansion is 
The coefficient of compressibility is 
Generally the ideal gas is mathematically represented as

=> 
differentiating both side with respect to T at constant P

substituting the equation above into 


Recall from ideal gas equation 
So

Now differentiate equation (1) above with respect to P at constant T

substituting the above equation into equation of 


Recall from ideal gas equation that

So

Now considering 
From equation (1) we have that

From ideal equation

So

=>
