The formula of Washing Soda is (Na2CO3.10H2O). It contains two atoms of Sodium,one atom of Carbon, thirteen atoms of Oxygen and twenty atoms of Hydrogen.
It's chemical name is Sodium Carbonate decahydrate. It is white coloured crystal which is basic in nature. So, it is called a basic salt. It turns red litmus paper into blue.
Answer:
720 divided by 2 answer is 556 so answer per is 3.32.3
Explanation:
We are given the molecular mass of tetraoxosulphate(VI) acid as 98 g/mol. The molecular formula of this is H₂SO₄ which is also known as sulfuric aid. The vapour density of a substance is the density of a vapour in relation to hydrogen gas. Therefore, it the mass of a volume of gas, divided by the mass of the same volume of hydrogen gas. We can use the following formula:
vapour density = molar mass of gas/ molar mass of H₂
vapour density = 98 g/mol H₂SO₄ / 2 g/mol H₂
vapour density = 49
The vapour density of tetraoxosulphate(IV) acid is found to be 49. It should also be noted that the vapour density is a unitless quantity.
Answer:
The presence of fructose in their diet
Explanation:
The independent variable in an experiment is the type of variable which is changed at intervals in order to study if it has a direct effect on the dependent variable.
The dependent variable in the experiment is the amount of weight gained by the mice in each group and the control group is the mice who drank the water without the fructose added.
