The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.
<h3>How magnesium hydroxide is formed?</h3>
It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.
The chemical equation between magnesium and water is given below:
Mg + 2H₂O -----> Mg (OH)₂ + H₂
So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.

<h3>
Answer:</h3>
81.9 grams
<h3>
Explanation:</h3>
From the question we are given;
- Half-life of C-14 is 5730 years
- Original mass of C-14 (N₀) = 150 grams
- Time taken, t = 5000 years
We are required to determine the mass left after 5000 years
- N = No(1/2)^t/T, where N is the remaining mass, N₀ is the original mass, t is the time taken and T is the half-life.
t/T = 5000 yrs ÷ 5730 yrs
= 0.873
N = 150 g ÷ 0.5^0.873
= 150 g × 0.546
= 81.9 g
Therefore, the mass of C-14 left after 5000 yrs is 81.9 g
Kinetic energy is produced when the amount of work done on an object relative to its change in energy.
Explanation:
A strong connection is present between within work as well as energy. When work is performed on an object energy is added along with it . Energy can be defined as ability to do certain amount of work on the other hand work means to change in energy . Kinetic energy is produced when the object is in moving position and potential energy is produced when the object is at resting position.
The earliest idea of the atom is that it is made up of tiny, invisible particles, called the atoms, is believed to have originated from the Greek philosopher Leucippus of Miletus and his student, Democritus of Abdera, around 5th century B.C. However, it wasn't until centuries later that the atomic theory was taken seriously by the society, thanks to the scientist John Dalton by 1808. Hence, the development of the Atomic Theory began until the modern age. Modern scientist has more technological advancements than the early age. Therefore, the modern scientist can view the atom more detailed than before.

Water is an example of a balanced synthesis equation: 2 H2(g) + O2(g) → 2 H2O(g). The number of atoms in the reactants and the number of atoms in the products must balance in a chemical equation.
<h3>What is balanced equation?</h3>
A chemical reaction equation is said to be balanced if both the reactants and the products have the same total charge and the same number of atoms in the reaction. In other words, both sides of the reaction have an equal mass and charge balance.
The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction. On the left and right sides of a balanced chemical equation, there are an equal number of atoms of each element.
Therefore,
Water: 2 H2(g) + O2(g) → 2 H2O(g)
2K + 2H2O → 2KOH + H.
NaCN ( a q ) + HBr ( a q ) → NaBr ( a q ) + HCN ( g )
2HgO(s)→2Hg(l)+O2(g)
2CH3OH + 3O2 → 4H2O + 2CO2
HCl(aq)+NaOH(aq)⇌NaCl(aq)+H2O
