Answer:
has very different properties from sodium and chlorine
Explanation:
We know that salt (chemical name: Sodium Chloride) is made from two elements, Sodium (Na) and Chlorine (Cl). But the properties of the compound of sodium and chlorine has completely different properties than those of its elements: Sodium and Chlorine.
Sodium is quite a low density but highly reactive silvery white metal and Chlorine is a highly reactive greenish yellow gas. While salt (NaCl) is a crystalline material, white in color, which readily dissolves in water and is used as a condiment to add flavor to food.

The mass of oxygen is 236.4 g.
Explanation:
To find the mass of oxygen in 325 g of carbon dioxide (CO₂) we follow the next algorithm.
First we calculate the molar weight of carbon dioxide:
molar weight of CO₂ = molar weight of carbon × 1 + molar weight of oxygen × 2
molar weight of CO₂ = 12 × 1 + 16 × 2 = 44 g/mole
Now we devise the following reasoning:
if in 44 g of CO₂ there are 32 g of oxygen
then in 325 g of CO₂ there are X g of oxygen
X = (32 × 325) / 44 = 236.4 g oxygen

<span>Water can absorb high
amounts of heat before there is an observed rise in temperature. It has the
highest heat capacity among all liquids. This is caused by the presence of
hydrogen bonding in water molecules which gives it stronger attraction between the molecules.</span>
That would be the exosphere. The reason it feels cold, despite high temperatures, is due to lower air density.
Hope it helps!
