Which statements regarding tectonic motion are correct? a.)continental plates plunge beneath oceanic plates during a collision. b.)earthquakes are the most common cause of tsunamis. c.)seafloor spreading occurs at convergent boundaries. d.)a volcanic eruption releases hot gases into the air. e.)a single hot spot can form multiple volcanoes due to plate motion. i need , it would be greatly appreciated! : )

The correct answers are B, D, and E.

Actually, on the contrary, to choice A, oceanic plates plunge beneath continental plates during a collision because they are heavier

On the contrary, to choice C, Seafloor spreading occurs at divergent boundaries.

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.
