Answer:
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up. Or by multiplying all the sides of the container. #markasbrainliest
The variable X is the effective nuclear charge, and it remains constant down a group.
Discussion:
The effective nuclear charge is referred to as the actual amount of positive (nuclear) charge experienced by an electron in a polyelectronic atom.
The effective nuclear charge experienced by an electron is otherwise called the core charge.
It is mathematically evaluated as the difference in the atomic number and the core electrons. and since elements in the same group have equal number of Valence electrons, the effective nuclear charge is constant down the group.

Answer:
9.92 g of Cl
Explanation:
Well first find out the molar mass of calcium hypochlorite.
The molecular formula is,
CaO₂Cl₂
Adding the atomic masses we get the molar mass = 142.98 g/mol
This means,
142.98 f of CaO₂Cl₂ = 70.91 g of Cl
Therefore,
20 g of CaO₂Cl₂ = X
Solving for X,
X = (70.91 g of Cl × 20 g of CaO₂Cl₂) ÷ 142.98 f of CaO₂Cl₂
X = 9.92 g of Cl
1.) A compound is a thing that is composed of two or more (separate) elements.
2.) A compound cannot be separated easily, while its properties differ from where it originates from. It also is formed from chemical reactions.
3.) A pure substance, also known as chemical substance, is a material with constant composition and consistant properties.
4.) If a substance is not a pure substance, then it is an impure substance.
Hope this helped. :)
