An ice cube is dropped into boiling water. How will heat flow between the water and the ice cube?

Answers

On a microscopic (molecular) level, heat flows from the ice to the boiling water
at a minuscule rate, and from the water to the ice at a humongous rate.

Heat transfers from hot body to cold body. So when ice is dropped in water , the water at higher temperature will lose heat energy and is gained by the ice at less temperature. When the Net heat lost equals to Net heat gained i.e.,When both the bodies attain themal equilibrium, the flow of heat energy stops and both attain equal temperatures.

Hydrazine, ammonia, and hydrogen azide all contain only nitrogen and hydrogen. The mass of the hydrogen that combines with 1.00g of each compound is 1.4 x 10^-1g, 2.4x10^-1 g and 2.40x10^-2 respectively. Show how these data illustrate the law of multiple proportions.

Answers

The law of multiple proportions, states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers. You divide each by the smallest, and you should get the right kind of ratio. We do as follows:

H in N2H4 = 1.4x10^-1
1.4x10^-1 / 2.4x10^-2 = 6

H in NH3 = 2.4x10^-1
2.4x10^-1 / 2.4x10^-2 = 10

H in HN3 = 2.4x10^-2
2.4x10^-2 / 2.4x10^-2 = 1

What is the ratio of al3+ ions to s2- ions in a neutral compound1:1
2:1
2:3
3:2

Answers

The ratio of Al^3+ ions to S^2- ions in a neutral compound is 2:3.

The neutral compound formed by aluminum ion and sulphide ion is aluminium sulphide, with chemical formula Al2S3. Looking at the chemical equation, you will observe that, for each molecule of aluminium sulphide, there is two atoms of aluminium and three atoms of sulphur. This is the ratio of combination for the compound, that is, for every two atoms of aluminium, there are three atoms of sulphur, thus, the combination ratio is 2:3.

2:3. The neutral compound formed between aluminium and sulfur is Al2S3 since aluminium has the valence 3 and sulfur is 2. So there are 2 aluminium atoms for every 3 sulfur atoms and the ratio is 2:3.
