Consider the chemical equation below.
igor_vitrenko [27]

Answer : The net ionic equation will be,

2H^{+}(aq)+2OH^-(aq)\rightarrow H_2O(l)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

Mg(OH)_2(aq)+2HNO_3(aq)\rightarrow Mg(NO_3)_2(aq)+H_2O(l)

The ionic equation in separated aqueous solution will be,

Mg^{2+}(aq)+2OH^-(aq)+2H^{+}(aq)+2NO_3^{-}(aq)\rightarrow H_2O(l)+Mg^{2+}(aq)+2NO_3^{-}(aq)

In this equation, Mg^{2+}\text{ and }NO_3^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

2H^{+}(aq)+2OH^-(aq)\rightarrow H_2O(l)

While investigating greenhouse gases, I measured 0.1875 grams of carbon dioxide in a 500-gram sample of the atmosphere. What is
Harlamova29_29 [7]

Answer:

[CO₂] = 375 ppm

Explanation:

We can determine the concentration in value of ppm

ppm = mass of solute (mg) / mass of solution (kg)

Solution: atmosphere

Solute: CO₂

We convert the mass of CO₂ from g to mg → 0.1875 g . 1000 mg / 1g = 187.5 mg

We convert the mass of the atmosphere from g to kg: 500 g . 1 kg/1000g = 0.500 kg

ppm = 187.5 mg / 0.500kg = 375
