We have gravity here on earth while in space there’s none

Because of the moon's considerably lower gravity. The moon's gravity is about 1/4 as strong as the earth's gravity.
Our muscles a built to carry us on the earth. The astronauts are used to walking on earth so when they push forward with their legs they tend to use the same amount of energy which is 4 times more than needed. That push causes them to rise, Newton's second law

The molar mass of O2 is 32.0 g/mol.what mass,in grams,of O2 is required to react completely with 4.00 mol of Mg

Dahasolnce [82]

The balanced equation for the reaction between Mg and O₂ is as follows
2Mg + O₂ --> 2MgO
stoichiometry between Mg and O₂ is 2:1
number of Mg reacted - 4.00 mol
if 2 mol of Mg reacts with 1 mol of O₂
then 4.00 mol of Mg requires - 1/2 x 4.00 = 2.00 mol of O₂
then the mass of O₂ required - 2.00 mol x 32.0 g/mol = 64.0 g
64.0 g of O₂ is required for the reaction

Calculate how many grams of oxygen form when 2.72 g of KCIOg reacts completely given the

34kurt

1.06g

Please refer to the image attached.

You first find the number of moles (n) for KClO3 as you have been given the mass. So n = mass/Mr gives you the moles that is 0.022 mol

Next you use the ratio 2:3 as per the equation where it's 2KClO3 ---> 3O2 so you just cross multiply and get the moles for oxygen.

Now that you know the number of moles for oxygen, you can use the same moles equation that you used earlier to find the mass. mass=n×Mr and so you get the answer as 1.06g of oxygen.
