Answer:

0.10 mol of sulfuric acid will neutralize 0.10 mol of calcium hydroxide.

Explanation:

H_2SO_4+Ca(OH)_2\rightarrow CaSO_4+2H_2O

1 mol of sulfuric acid reacts or neutralizes with 1 mol of calcium hydroxide.

Then 0.10 mole of calcium hydroxide will be neutralized by:

\frac{1}{1}\times 0.10 mol= 0.10 mol of sulfuric acid

0.10 mol of sulfuric acid will neutralize 0.10 mol of calcium hydroxide.

Mole ratio:

H2SO4 + Ca(OH)2 = CaSO4 + 2 H2O

1 mole H2SO4 ----------- 1 mole Ca(OH)2
? moles H2SO4 --------- 0.10 moles Ca(OH)2

0.10 x 1 / 1

= 0.10 moles of H2SO4

The formation of tert-butanol is described by the following chemical equation:
fomenos

Answer:

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

Explanation:

This reaction involves;

First the ionization of the tertiary halide to firm a carbocation

Secondly the attack of the hydroxide ion on the carbocation to form tert-butanol

First step;

(CH3)3CBr (aq) → (CH3)3C+ (aq) + Br- (aq)

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

This second step completes the reaction mechanism.

An oxide of nitrogen contains 30.45 mass % N.
N76 [4]

An oxide of nitrogen contains 30.45 mass % N, if the molar mass is 90± 5 g/mol the molecular formula is N₂O₄.

<h3>What is molar mass?</h3>

The molar mass of a chemical compound is determined by dividing its mass by the quantity of that compound, expressed as the number of moles in the sample, measured in moles. A substance's molar mass is one of its properties. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes.

<h3>How to find the molecular formula?</h3>

The whole-number multiple is defined as follows.

Whole-number multiple = \frac{molar mass (g/mol)}{empirical formula mass (g/mol)}

The empirical formula mass is shown below.

Mw of empirical formula = Mw of N+ 2 x (Mw of O)

                                      = 14.01 g/mol + 2 x (16.00 g/mol)

                                      = 46.01 g/mol

With the given molar mass or the molecular formula mass, we can get the whole-number multiple for the compound.

Whole-number multiple = \frac{90 g/mol }{46.01 g/mol} ≈ 2

Multiplying the subscripts of NO2 by 2, the molecular formula is N(1x2)O(2x2)= N2O4.

Magnesium reacts very slowly to form magnesium hydroxide and hydrogen gas. Write a word amd chemical equation for this reaction.
Varvara68 [4.7K]

Answer: -

Magnesium reacts very slowly to form magnesium hydroxide and hydrogen gas. The balanced chemical equation for the reaction is

Mg + 2H₂O → Mg(OH)₂ + H₂

Explanation: -

Chemical symbol of magnesium = Mg

Chemical formula for magnesium hydroxide = Mg(OH)₂

Chemical formula for hydrogen gas = H₂

The other reactant with Mg must be water H₂O.

Thus the balanced chemical equation for the reaction is

Mg + 2H₂O → Mg(OH)₂ + H₂
