C because it’s just leaning against the wall it’s not moving
Answer:
Explanation:
Butane is the 4th member of alkane series. It has 4 carbon atoms.
First write a balanced equation for the combustion of butane as follows;
2C4H10 + 13O2 ===> 8CO2 + 10H2O
from the balanced equation,
2C4H10 weigh 2[(12 x 4) + (1 x 10)]
=2(48 + 10)
= 116g
13O2 weigh 13(16 x 2)
=13 x 32
= 416g
8CO2 weigh 8[ 12+ (16 x 2)]
8 x (12 + 32)
352g
From the equation, 116g of buthane produced 352g of carbon dioxide
10g of buthane will produce 10×116÷352 =
Answer:
Average atomic mass of chlorine is 35.48 amu.
Explanation:
Given data:
Percent abundance of Cl-35 = 76%
Percent abundance of Cl-37 = 24%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (76×35)+(24×37) /100
Average atomic mass = 2660 + 888 / 100
Average atomic mass = 3548/ 100
Average atomic mass = 35.48 amu
Average atomic mass of chlorine is 35.48 amu.
Answer:
2H2 + O2 -------------> 2H2O
I would guess therefore 2 x 2.50 L or 5.00 L
