The ratio of chlorine to hydrogen chloride in the reaction

h2(g) + cl2 (g) -> 2 hcl(g) is

1:2.

Explanation:

H₂(g) + Cl₂(g) → 2HCl(g),

1.0 mole of H₂(g) reacts with 1.0 mole of Cl₂(g) to produce 2.0 moles HCl(g),

∴ The ratio of chlorine (Cl₂(g)) to hydrogen chloride (HCl(g)) is 1:2.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
