Answer:
A covalent chemical bond is one in which <u>outer-shell electrons of two atoms are shared so as to satisfactorily fill their respective orbitals</u>.
Explanation:
Covalent bonds are formed between two atoms having their electronegativity difference less than 1.7. In this type of bonding the valence electrons of one atoms forms molecular bond with the valence electrons of another atom. The electrons are mutually shared.
Covalent bond can be non-polar as for example formed between hydrogen and carbon atoms.
Also, covalent bond can be polar in nature as that formed between hydrogen and chlorine atoms because the chlorine atom is more electronegative and hence attracts the electrons more towards itself making density of electrons less on hydrogen atom.
C. Increasing the volume of gas particles of H2 and I2 will decrease the rate of the forward reaction. As the gas particles will not undergo frequent collisions as much and thus will not produce as much product.

Explanation:
Given parameters:
Volume of helium blimp = 6.28 x 10⁹mm
Density of helium in the blimp = 0.1786g/cm³
Unknown:
Mass of helium in the blimp = ?
Solution:
Density is defined as the mass per given volume of a substance.
Density =
We need to convert the volume to a unit we can work with which is cm³
1000L = 1cm³
1mL = 10⁻³L or
1000mL = 1L
6.28 x 10⁹mL =
= 6.28 x 10⁶L
since 1000L = 1cm³
6.28 x 10⁶L gives
= 6.28 x 10³cm³
Mass = density x volume = 0.1786 x 6.28 x 10³m³ = 1121.608g or 1.12kg
