If 250 g of calcium chlorate decomposes into calcium chloride and oxygen, what mass of oxygen would be produced?

→ +

115.95 grams of oxygen

Explanation:

The reaction equations is expressed as:

We know the molar mass of as hence the number of moles in the 250g reaction is

#Given the 1:3 ratio(to oxygen's moles), the number of moles of oxygen produced is:

The molar mass of oxygen is 32g, therefore:

Hence, 115.95 grams of oxygen are produced.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
