Answer:
(B) II, IV.
hope this answer is helpful for u.
So multiply number of moles x number of atoms/mole = 1.8066 x 10^24 atoms of H2. One mole of any gas at STP has a volume of 22.4 L. So first determine the number of moles of gas you have.
for example do 7

that 's what I think
Answer:
no it will have no charge...it would be electrically neutral! because the number of protons and electrons are equal!
Answer:
it's SN1 reaction,
it's takin double step to complete,first formation of carbocation and then attack of reagents,so it's SN1!
The answer is proton-electron attraction. All chemical bonds whatever the type will end up in one single idea that protons attracts electrons. The protons in the nuclei of an atom attracts all electrons near, those that came with the atom itself and electrons of atoms nearby. The two atoms get closer and a chemical bond is formed.
