Explanation:
Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.
Answer:
Explanation:
follow the rule of "a weak acid can't make a stronger acid and weak base can't make a stronger base(it's pretty accurate for acid/salt reactions/replacemnts)" the last reactions won't work, but the second to last one will be kbr+pb(no3)2-> kno3 + PbBr2 (this is unballanced.) the first reaction will work. the second one i'm not too sure tbh, but i think it won't work since barium hydroxide's a weak base and if it were to react it would make koh, a super strong base

the answer is 2 hope this helps
Answer:
There are a total of 8 electrons around the carbon, in 4 pairs. Because there are 4 bonds, these are all bond pairs. Each double bond uses 2 bond pairs - which are then thought of as a single unit.
