Answer:
A substance is a form of matter that will have a constant composition of evenly distributed products.
Explanation:
(Has to be the same everywhere)
Answer:
3984.12 J joules of heat are required to heat 25.0 g of isopropyl alcohol to its boiling point.
Explanation:

Where:
Q = heat absorbed or heat lost
c = specific heat of substance
m = Mass of the substance
ΔT = change in temperature of the substance
= Initial temperature of the substance
= Final temperature of the substance
We have mass of isopropyl alcohol = m = 25.0 g
Specific heat of isopropyl alcohol = c = 2.604 J/g°C
Initial temperature of the isopropyl alcohol = 
Final temperature of the isopropyl alcohol = 
Heat absorbed by the isopropyl alcohol to boil:

3984.12 J joules of heat are required to heat 25.0 g of isopropyl alcohol to its boiling point.
Answer:
D
Explanation:
The picture depicts the data of the chemical, explaining that as the temperature rises, the chemical reaction rate would increase as well.
Hello.
The answer is <span>+313.766 J/mol·K
</span>
Use the coefficients of the reaction and sum the product entropies less the reactant entropies:
4*188.8 + 2*213.7 - 3*205.1 - 2* 126.8 = 313.7 J/mol*K
Have a nice day
