Suppose during volleyball practice you lost 2.o lbs of water due to sweating if all of this water evaporated how much energy did the water absorb from your body 2.2lbs=1.0 kg

2054.86 kJ

Explanation:

Given: 2.2 lbs = 1.0 kg

Q= heat gained

n =

n =no of moles =

 = enthalpy of vaporization of water = 40.65 kJ/mol

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
