Can you please solve this. ..above question

(dont know if this is correct took this last year)

Explanation:

1 hydrogen atom plus 1 chlorine atom is equal to 2 hydrochloric acids due to the fact that there are 2 atoms in both substances and the equation has to stay constant throughout according to the law of conservation of mass

same goes for 2 sulfate atoms  and 3 oxygen atoms

in order to balance this this the sulfate atoms have to take into account that their are 2 sulfate atoms and 6 oxygen atoms  so you have to add more sulfates to make them both equal 6 then balance it with the oxygens

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

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 : )
