Answer : 1.593 moles are equal to 89.23 g of calcium oxide.
Solution : Given,
Mass of calcium oxide = 89.23 g
Molar mass of calcium oxide = 56 g/mole
Formula used :
Now put all the given values in this formula, we get the moles of calcium oxide.
Therefore, 1.593 moles are equal to 89.23 g of calcium oxide.
The answer to your question is letter B. conservation of mass
A.molecular changes I think there is no molecular changes law so this option is discarded.
B.conservation of mass This law states that the number of products is equal to the amount of reactants so if chemical equations are balanced, they satisfied this law.
C.conservation of energy This law states that the total energy in an isolated system remains constant and is different from the chemical equations so this option is discarded.
D.products and reactants are elements of a chemical reaction but they are not a law, so this option is discarded.
Yes, depending on the thickness.
At a constant 100km/hr, you would travel 600km
Have a good day :)
I think it's 4
Because the last two zeros won't be needed
The answer would be 1.56 mol H2SO4.
Hoped I help :)
