Answer:
A. boiling point
Explanation:
The correct answer is;
A. boiling point
The boiling point of a liquid is the temperature at which the vapour pressure is equal to the atmospheric pressure.
B. melting point
This option is wrong because the melting point is the temperature at which a solid undergoes a phase change to a liquid.
C. freezing point
This option is wrong because the freezing point is the temperature at which a liquid undergoes a phase change to a solid.
The answer is "<span>An atomic nucleus is positively charged because it is composed of protons". An atomic nucleus actually contains nucleons which are made up of both protons and neutrons. Since neutrons are neutral or have no charge, the charge of an atomic nucleus mainly relies on the positive charge of the protons.</span>
Answer:
Compounds can be broken down into simpler substances by chemical means, but elements cannot. break a compound into simpler substances; oxygen and hydrogen that water contains.
But where is the following?
Answer:
Here's what I get
Explanation:
The fatty acids form ester C-O bonds with the OH groups of glycerol and the phosphoric acid forms phosphate P-O bonds.
The phosphate also forms P-O ester linkages with the OH groups in other alcohols such as choline.
The structure below shows the phospholipid with two saturated C₈ fatty acids and the phosphate group.
Because of their atom's composition. some are naturally packed closer together and stronger and more durable, while others tend to be more loose and breakable and/or weaker/less durable. also with how their atoms are composed is how the atoms interact with each other/ how they share or give or take electrons.
