Identify the Bronsted-Lowry acid-base pair in the following equation:

HCN + NO2- ⇌ CN- + HNO2

      HCN    +       NO₂⁻        ⇌               CN⁻            +          HNO₂

Weak acid     Strong base        Conj. strong base      Conj. weak acid

Explanation:

In the Bronsted-Lowry theory we identify the acids as the compounds that can release protons and the bases, the compounds that can accept them.

For example:

HCl → It can release the proton → Acid → Hydrochloric acid

NH₃ → It can accept a proton → Base → Ammonia

The equation is:

HCN + NO₂⁻ ⇌ CN⁻ + HNO₂

Cianhydric acid release a proton (acid) to the nitrite (base).

Nitrite can accept the proton (base) to become nitrous acid.

Then, the cianide can also accept the proton (base) to become cianhydric acid, again.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
