Answer: what
Step-by-step explanation:
Answer: 36 moles oxygen
Step-by-step explanation:
C10H8 + 12O2 ====》 10CO2 + 4H2O
From the equation of the reaction,
1 mole of napth requires 12 moles of O2
3 moles of napth would require x moles O2
X = (3 * 12) / 1
X = 36 moles of oxygen.
Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen
Answer:
x = 8.5
Step-by-step explanation:
I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.
first, make an equation:
x + 8 = 3x - 9
bring 3x to the other side, by subtracting it
-2x + 8 = -9
Subtract 8
-2x = -17
divide by -2
x = 8.5
Then, just sub x into the formulas
Answer:
D
Step-by-step explanation:
C=2PI R
Radius is 24
pi is 3.14
Then you just solve it which turns out to be 150.8
