Consider the balanced chemical equation 4B(s) + 302 (g)► 2B203(s)
What mole ratio would you use to calculate how many moles of oxygen gas would be needed to react completely with a given number of moles of boron?

A. 3 mol O2
/ 4 mol B
B. 4 mol O2/
3 mol B
C. 3 mol O2/
2 mol B
D.
2 mol O2
/ 3 mol B

A

Explanation:

The coefficents are used when determining mole ratio. So just look in front of O and B

the ratio is 3/4

you cna use this in stoich as well

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
