143/80 = 1 63/80 (use cymath!! it helps!!)
Answer:
x=1. 3*1=3 so we'll say 3 instead of 3x. ([6*2]+[3*2])=(6*3)
P.s.
Can you please give me brainliest for my next rank.
Answer:
Step-by-step explanation:
Given : P(A)=0.60 and P(B)=0.30
We will say A and B are independent events if :
Thus , A and B are independent events if :
Given:
hydrazine (N2H4) to hydrogen peroxide (H2O2)
Find: mole ratio
Solution
the molar mass of hydrazine, N2H4 = 32 g/mol
the molar mass of hydrogen peroxide, H2O2 = 34 g/mol
mole ratio of hydrazine to hydrogen peroxide = 32g/mol / 34 g/mol = 16/17
