Answer:
c. An ionic bond is much stronger than most covalent bonds
Explanation:
Ionic bonds are interatomic bonds that forms as a result of electrostatic attraction between two ions. For an ionic bond to be formed, one atom must have lost or gained electron from another that is transferring it. Ionic bonds typically form between atoms whose electronegativity differences are far apart.
Ionic bonds are usually stronger than other types of bonds due to the electrostatic attraction between ions.
One very distinct feature about ionic compounds is that they are conductors of electricity in either molten or aqueous. At room temperature, they are solids and contains no mobile ions.

Tests for gases
Hydrogen, oxygen, carbon dioxide, ammonia and chlorine can be identified using different tests.
Hydrogen. A lighted wooden splint makes a popping sound in a test tube of hydrogen.
Oxygen. A glowing wooden splint relights in a test tube of oxygen.

Answer:
<span>Formula for sodium hydroxide is represented by <u>NaOH</u>.
Explanation:
The reaction of Sodium oxide with water is as follow,
Na</span>₂O + H₂O → 2 NaOH
<span>
Na</span>₂O is considered as a strong basic oxide as it contains O²⁻ which has high tendency to bind with hydrogen atoms. This reaction is an exothermic reaction and is conducted in cold water to produce NaOH.<span>

Explanation:
Answer:
The molar mass of carbon
Explanation:
Before the mass (in grams) of two moles of carbon can be determined, <u>the molar mass of the element would be needed.</u>
<em>This is because the number of mole of an element is the ratio of its mass and the molar mass</em>. That is,
number of mole = mass/molar mass
Hence, the mass of elements can be obtained by making it the subject of the formular;
mass = number of mole x molar mass
<em>Therefore, the molar mass of carbon would be needed before the mass of 2 moles of the element can be determined.</em>
