How does the formation of water from hydrogen and oxygen demonstrate the conservation of mass? (1 point)

Chemistry
1 answer:
Norma-Jean [14]3 years ago
4 0

Answer:

Water has a chemical formula of H2O . In here, there are two hydrogen atoms and one oxygen atom, and so its mass will be 2+16=18 amu . There are two water molecules formed, and that means the total mass of the products is 18⋅2=36 amu .

g Increasing the number of unsaturations in a fatty acid ____________ the melting temperature of the fatty acid.
Trava [24]

Answer:

Decreases

Explanation:

Fatty acid which have the double bond or triple bond are called unsaturated fatty acids. Because of the double or triple bond, unsaturated fatty acids are loosely packed and form some distance among molecules which lowers the melting point of unsaturated fatty acids.

So, if the unsaturation of fatty acid will increase, it leads to more branched and loosely packed molecules and decreases the melting temperature accordingly.
