Answer:
This question is incomplete
Explanation:
This question is incomplete but what you should know is that isopropanol (also referred to rubbing alcohol) has just one functional group. This functional group is called the hydroxyl group (-OH) and it's the reason the compound name ends with "ol". The hydroxyl group can be seen in the structure of the compound (Isopropanol) below
H OH H
| | |
H- C - C - C - H

H H H
If there is any functional group in isopropanol required for any form of interaction, that functional group will be the hydroxyl group because that's the only functional group isopropanol has.
NOTE: Functional group is an atom or group of atoms that determines the chemical properties of a compound.
Answer: Lead chloride solution is A SUBSTANCE.
In chemistry, all matters are divided into mixtures and pure substances. The pure substances are made up of one type of particle while the mixtures are made up of different particles. The pure substances can be in form of an element or a compound. Lead chloride for instance is a compound and is a pure substance.
Good luck!!! Hope this helps!!! ;)
Answer:

Explanation:
Answer:
60.01 kJ energy to melt 180g of ice, <em><u>assuming my figure for heat of fusion.</u></em>
<em><u>Explanation:</u></em>
Please check the wording of the question. "6,01 kmoland the molar - mass of ice is 18.02 g/mol" is hard to interpret.
<em><u>I'll assume the heat of fusion of ice is 6.01 kJ/mole</u></em>?
180 grams of solid water (ice) is 180g/(18.02 g/mole) or 9.999 moles, rounded to 3 sig figs to 10 moles.
(10 moles H2O)*(6.01 kJ/mole) = 60.01 kJ energy to melt 180g of ice.
