Answer
2 HCIO4 + Ba(OH)2 + Ba(CIO4)2 + 2 H2O
1.
grams Ba(CIO4)2
If 2.75 grams of Ba(OH)2 are reacted, how many grams of Ba(CIO4)2 will be produced?
2 ZnO + 2Cl2 → 2 ZnCl2 + O2
2
grams 02
If 285.92 grams of ZnO are reacted, how many grams of O2 will be produced?
2 SO2 + O2-2 SO3
3.
grams SO
If 351.95 grams of O2 are reacted, how many grams of So, will be produced?
Pb + CuSO4 → PbSO4 + Cu
4
grams PbSO4
If 236.08 grams of Pb are reacted, how many grams of PbSO4 will be produced?
PA + 6 Br2 - 4 PBr3
5.
grams PA
If 173.81 grams of PBrs are produced, how many grams of Pa were reacted?

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Afraidsugar lol it’s the third one
