Ans:
It is also known as law of multiple proportion. It states that if two elements form more than one compound between them then the ratios of the masses of the second element which combine with the fixed mass of first element will be ratios of small whole numbers.

Answer:
Brittany is studying the properties of a sample of iron. Whether she studies a large sample or a small sample, the <u><em>properties</em></u> of iron will always be the same.
Explanation:
The properties of an element will always remain the same no matter if we change the quantity of the element.
Iron is a chemical element with atomic number 26. It belongs to group 8 of the periodic table.
The properties of iron are:
- It is a shiny metal.
- It is soft, malleable and ductile.
- It combines readily with oxygen in the air and hence can be rusty in the damp air.
Boron have 5 protons and only 4 electrons, which means that it has a positive charge.
(The charge is +1)

Answer:
Quantitative experiments show that 4.18 Joules of heat energy are required to raise the temperature of 1g of water by 1°C. Thus, a liter (1000g) of water that increased from 24 to 25°C has absorbed 4.18 J/g°C x 1000g x 1°C or 4180 Joules of energy.
