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:
Yes Nitrogen has 7 Neutrons
Explanation:
<h3><u>Answer;</u></h3>
= 1.615 moles
<h3><u>Explanation</u>;</h3>
The molar mass of NO2
= 46.01 g/mol
The mass of NO2 given is 74.3 g
Number moles = mass/ molar mass
= 74.3 g/ 46.01 g/mol
= 1.615 moles

Coal is mainly made of carbon and there’s oxygen in the air so this burns to produce carbon dioxide. Breathing it can really hurt your lungs.
