<h2>Answer</h2><h3>C. Mg</h3><h2>Explanation:</h2>

When magnesium is in the metallic form it gets burn very easily in air. To start the reaction, the magnesium metal requires a source of energy. The flame provides heat so that the magnesium can overcome their activation energy. Activation energy is the minimum amount of energy needed in the system for a chemical reaction to proceed. Oxygen found in the air forms Magnesium Oxide when the magnesium metal burns in the air. A compound is in which atoms of different elements are linked or bonded to one another. Oxygen and magnesium react to form this compound and forms a white powder of the magnesium oxide that brightens it up.

How many milliliters of 4.00 M NaOH are required to exactly neutralize 50.0 milliliters of a 2.00 M solution of HNO3 ?
kramer

Answer: The volume of NaOH required is 25.0 ml

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

n_1 = basicity HNO_3 = 1

M_1 = molarity of HNO_3 solution = 2.00 M

V_1 = volume of  HNO_3 solution = 50.0 ml

n_2 = acidity of NaOH = 1

M_1 = molarity of NaOH solution = 4.00 M

V_1 = volume of  NaOH solution =  ?

Putting in the values we get:

1\times 2.00\times 50.0=1\times 4.00\times V_2

V_2=25.0ml

Therefore, volume of NaOH required is 25.0 ml

Answer:

Bonding in chemistry is known as chemical bonding which means the interaction or attraction between molecules.

Chemical bonds are of different type such as ionic, covalent, hydrogen, and metallic. Ionic bonds are formed by the transfer of valence electron from one atom to other and there is unequal distribution of electrons between two or more atoms. Ionic bonds forms two oppositely charges ions positively charged (loses electron) or negatively charged (gains electron).

Covalent bond are the strong chemical bonds that form due to equal sharing of electron pairs between atoms. They form a stable element and have stable attraction or repulsive forces.
