Answer: There are formula units
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of contains =
formula units
Thus 0.38 moles of contains =
formula units
Thus there are formula units
Answer:
Explanation:
Hello there!
In this case, for the reaction by which water is decomposed to molecular hydrogen and oxygen:
It is necessary to perform the inspection balance process since there is a dissimilar number of atoms of oxygen on both sides; therefore, by putting a 2 on water we balance oxygen:
But now, there are four hydrogens on the left; therefore, we put a 2 on hydrogen to finally balance it:
And obviously, the coefficient in oxygen is an unwritten 1.
Best regards!
