Which of the following are said to be physical properties of gases? Select one: a.) The atoms or molecules of a gas are relatively far apart.
b.) A gas expands to fill the space in a closed container.
c.) A gas is easily compressed.
d.) all of the above.
e.) Answers A and B only.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the temperature of the gas, in k, not celsius.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

i think its 5049.

i hope this !
