Answer:
It’s true
Explanation:
If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system. ... The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth.
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
Answer:
61.994 g
Explanation:
first of all the result is not balanced but here is tje answer anyways
To find the weight we have to add their molar mass
12.011+(15.99×2)+(1.002×2) +15.999=61.994
