Answer: $H_2SO_4(aq)$

Explanation:

An acid is defined as the acid which completely dissociates when dissolved in water and release $H^+$ ions in their aqueous states.

A base is defined as the base which completely dissociates when dissolved in water and releases $OH^-$ ions in their aqueous states.

$Mg$ is an element, $H_2$ is a compound, $MgSO_4$ is a salt formed by combination of acid and base.

The equation for the dissociation of sulphuric acid is given by:

$H_2SO_4(aq.)\rightarrow 2H^+(aq.)+SO_4^{2-}(aq.)$

Answer:

H2SO4

Explanation:

H2SO4 is actually one of the strongest acids, coming to a pH value very close to 1. Acids transfer their hydrogen ions to other substances, such as water, and usually have hydrogen in their formula. In this case, H2SO4 has hydrogen in its formula and is the acid in this case.

Enter a balanced equation for the complete combustion of liquid C3H7OH. Express your answer as a chemical equation. Identify all

Vlad1618 [11]

2 C₃H₇OH (l) + 9 O₂ (g) → 6 CO₂ (g) + 8 H₂O (g)

Explanation:

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

Bellow we have the balanced chemical equation of the complete combustion of C₃H₇OH:

C₃H₇OH (l) + (9/2) O₂ (g) → 3 CO₂ (g) + 4 H₂O (g)

to have integer coefficients we multiply the reaction with 2:

2 C₃H₇OH (l) + 9 O₂ (g) → 6 CO₂ (g) + 8 H₂O (g)

where:

(l) - liquid

(g) - gaseous
