Answer: They would both be pushed backward. (READ EXPLANATION)
Explanation:
Since your question has an error in it, I will provide two answers. If they were standing on their feet, they would not move. if they're both standing on skateboards, they would both move backwards because they have no friction on the ground. if both of them are standing on the same skateboard and pushing against each other, they would not move.

A solution is made when one substance called the solute "dissolves" into another substance called the solvent. Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules.
<h3>Answer:</h3>
C₆H₁₄ is the only Alkane in given compounds.
<h3>Explanation:</h3>
The General Formula for Alkanes is as follow;
Cₓ H₂ₓ ₊ ₂
where;
x = whole number
It means in alkanes for every x number of carbon atoms we have 2x + 2 number of hydrogen atoms. Let's apply this formula on given compounds.
CH₂O:
As there is one carbon atom in this compound hence, the number of hydrogen atoms present for one carbon atom in alkane must be equal to,
H₂₍₁₎ ₊ ₂
H₂ ₊ ₂
H₄
Hence, this compound is not alkane because it contains only two hydrogen atoms.
C₆H₁₄:
As there are six carbon atoms in this compound hence, the number of hydrogen atoms present for six carbon atoms in alkane must be equal to,
H₂₍₆₎ ₊ ₂
H₁₂ ₊ ₂
H₁₄
Hence, this compound is alkane because it contains fourteen hydrogen atoms.
C₃H₄:
As there are three carbon atoms in this compound hence, the number of hydrogen atoms present for three carbon atoms in alkane must be equal to,
H₂₍₃₎ ₊ ₂
H₆ ₊ ₂
H₈
Hence, this compound is not alkane because it contains only four hydrogen atoms.
Answer:
Arsenic
Explanation:
This is because it has atomic number 33
