Pls Solve this!!!Im giving 20 points and Brainliest to the one who answers first. HELP ME PLEASE!!!!!!!!

Answer:

i) 2Mg + O₂ + Δ Heat → 2MgO + Δ Energy

ii) The aqueous solution does not change in the color of the blue litmus paper and the blue litmus paper remains blue in color

The aqueous solution formed using the product (MgO) turns the red litmus paper blue

Explanation:

i) Magnesium easily burns in air or oxygen when heated to form a white powder of magnesium oxide. The burning (reaction) of magnesium in air is an exothermic reaction that involves the release of heat and light

The burning of magnesium wire is given by the following chemical reaction;

2Mg + O₂ + Δ Heat → 2MgO + Δ Energy

ii) When magnesium oxide is mixed with water if forms magnesium hydroxide Mg(OH)₂ as shown in the following chemical reaction;

MgO + H₂O → Mg(OH)₂

Magnesium hydroxide is basic and therefore it will turn red litmus paper blue and it does not change the color of the blue litmus paper.

n which order did the events forming our solar system occur?

The solar nebula became hot and dense pulling in more gas.This flattened into a rotating disk. It spun faster and faster, forming the Sun.
Gas was pulled toward the center, forming the Sun. Gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster.
Gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster. Gas was pulled toward the center, forming the Sun.
The solar nebula spun faster and faster and flattened into a rotating disk. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.
