Answer:
74.566
Explanation:
C6H6 + 02 =6CO2 + 3H2O
2C6H6 + 15O2=12CO2 + 6H2O
mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol
mass conc = 2x78=156
mm CO2= 12+(16x2)=
12+32= 44gram/mol
mass conc of CO2 = 12x44
= 528
from The equation
156g of C6H6=528g of CO2
22.031g of C6H6=Xg of CO2
therefore, Xg=
22.031 x 528/ 156
= 74.566g
If I understand you correctly, then this is the equation for the breakdown of monosaccharide.
monosaccharide --> Carbon dioxide + water
Answer:
A an ionic compound that completely dissolves in water, forming many ions
Explanati
Answer:
500 years
Explanation:
The original carbon-14 was 100%, and after 100 years, it decays 1.202%. So after 100 years it goes to 98.798%, after more 100 years (200 years), it will be 97.596% (98.798 - 1.202), thus, after n 100 years "package", the percenatge will be:
100% - actual% = n*1.202
n = (100% - actual%)/1.202
n = (100% - 94%)/1.202
n = 4.992
So, the number of years is n*100 = 4.992*100 = 499.2 ≅ 500 years.
