Write a balanced half-reaction describing the reduction of gaseous dioxygen to aqueous oxide anions.

maksim [4K]

Answer: The balanced half reaction is written below.

Explanation:

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

When oxygen gas is reduced to oxide ions, the number of electron transferred are 2

The chemical equation for the reduction of oxygen gas to oxide ions follows:

$O_2+2e^-\rightarrow 2O^{2-}$

Hence, the balanced half reaction is written above.

S + 02 C + 02 Cu0 + H2SO4

vlabodo [156]

Answer:

S + 02= S0 - 4 e- → SIV (oxidation); 2 O0 + 4 e- → 2 O-II (reduction)

C + 02= C

Cu0 + H2SO4= CuO + H2SO4 → CuSO4 + H2O

How do you measure buoyancy

Usimov [2.4K]

1. First, you must find the volume of the container holding the liquid. (Length x Width x Height)
2. Find the density of the liquid you are submerging the object in. (D = Mass/Volume)
3. Find the force of gravity. (9.81 Newtons/Kilograms)
4. Multiply (Volume x Density x Gravity).
