Answer :

(1) KOH is act as a base and H_2SO_4 act as an acid.

(2) We can not classified as a base or an acid.

Explanation :

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydronium ions (H_3O^+) in water.

(1) The given chemical reaction is:

2KOH(aq)+H_2SO_4(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)

In this reaction, KOH produces OH^- ions and H_2SO_4 produces H^+ ions.

Thus, KOH is act as a base and H_2SO_4 act as an acid.

(2) The given chemical reaction is:

NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)

Arrhenius concept is only applicable on aqueous solution. Thus, we can not classified as a base or an acid.

Explain, in terms of subatomic particles, why atoms of H-1, H-2, and H-3 are each electrically neutral.
jasenka [17]

The atoms are all electrically neutral because the number of protons is equal to the number of electrons.

<h3>What is electrical neutrality?</h3>

An atom is electrically neutral when the number of protons is equal to the number of electrons.

In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.

What happens to the partial pressure of oxygen in a sample of air if the temperature is increased?
ludmilkaskok [199]

Air is mainly composed of N2  (78%), O2 (21%) and other trace gases. Now, the total pressure of air is the sum of the partial pressures of the constituent gases. The partial pressure of each gas, for example say O2, can be expressed as:

p(O2) = mole fraction of O2 * P(total, air)  ----(1)

Thus, the partial pressure is directly proportional to the total pressure. If we consider a sealed container then, as the temperature of air increases so will its pressure. Based on equation (1) an increase in the pressure of air should also increase the partial pressure of oxygen.
