The formula of metal hydroxides for

A) metal A = A(OH)

B) metal B = B(OH)₂

C) metal C = C(OH)₃

<h3>What are hydroxides?</h3>

When a metal's oxide combines with water, a hydroxide is created.

The general formula of hydroxide is:

M(OH)ₙ

where n is the valency of metal.

OH has a valency of -1

A) The formula of hydroxide of metal A:

The valency of metal A is 1

This means, here, n = 1

Therefore, the metal hydroxide formula will be = A(OH)

B) The formula of hydroxide of metal B:

The valency of metal B is 2

This means, here, n = 2

Therefore, the metal hydroxide formula will be = B(OH)₂

C) The formula of hydroxide of metal C:

The valency of metal C is 3

This means, here, n = 3

Therefore, the metal hydroxide formula will be = C(OH)₃

I am finding the formula of a compound that has 60% Carbon, 32% Oxygen, and 8% Hydrogen. Although, when it comes to actually cre
nataly862011 [7]

Answer:

Explanation:

To determine the molecular formula of the compound, the empirical formula must be determined first. To determine the empirical formula, the percentage of each constituent is divided by its molar mass. This is shown below

Carbon = 60/12 = 5

Oxygen = 32/16 = 2

Hydrogen = 8/1 = 8

The next step is to divide each ratio by the smallest value. The smallest value is 2. It becomes

Carbon = 5/2 = 2.5

It is approximated to 3

Oxygen = 2/2 = 1

Hydrogen = 8/2 = 4

Therefore, the empirical formula is

C3H4O

From the given relative molecular mass of the compound, the molecular formula can be determined

If you weighed out 0.38 g of calcium and reacted it with an excess of hcl, how many moles of h2(g) would you expect to produce?
Hitman42 [59]
Answer is: 0,0095 mol of hydrogen gas will be produced in reaction.
Chemical reaction: Ca + 2HCl → CaCl₂ + H₂.
m(Ca) = 0,38 g.
n(H₂) = ?
n(Ca) = m(Ca) ÷ M(Ca).
n(Ca) = 0,38 g ÷ 40 g/mol
n(Ca) = 0,0095 mol.
from reaction: n(Ca) : n(H₂) = 1 : 1.
n(H₂) = n(Ca) = 0,0095 mol.
n - amount of substance.

When you take 10 grams of salt, and dissolve it in 25 grams of hot water what is the solubility
AURORKA [14]

Answer:

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
