Answer: A) AgNO_3

Explanation: All acetates are soluble.

All compounds of Alkali metals are soluble.

Bromides of Barium, and copper are soluble but that of silver is insoluble.

So, to separate bromide ion from acetate ion, we need to mix silver nitrate to the mixture.

Hence, the right choice is A) AgNO_3 .

AgNO_3(aq)+Br^-(aq)\rightarrow AgBr(s)+NO_3^-(aq)

Read the given expression.
vovangra [49]

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.

Calculate the mass of chlorine in a 20g tablet of calcium hypochlorite​
Kobotan [32]

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. :)
