Afamily has a furnace that uses natural gas to heat their home. they are moving to an area that offers the option of using energy from a solar power plant to heat their home. which disadvantage will the family most likely face by making this switch?

The family will switch towards the less reliable production of heat.

Explanation:

The solar power plant's energy is attained from the radiation of the Sun. However, the energy from the Sun is less dependable as it is completely dependent upon weather. The solar energy is generally collected when it is sunny outside. At the time of rainy and cloudy days, the efficacy of the solar system gets diminished, and also at the time of night, the solar energy cannot be gathered. The other demerits of the solar system are that it is expensive, is associated with pollution, and consumes an ample amount of space.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

c. 75.7

i think that is the right
