Answer:
For each balanced reaction, indicate the total number of atoms in the table below. Reaction. Total Number of Atoms. Reactant Side 1 Product Side. (Left).
Explanation:
Answer:
iron (III) oxide is a gas
It is B I think but I’m not completely sure
When we can get the Kinetic energy from this formula KE= 1/2 M V^2
and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so,
KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force and H is the height of the fall.
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
It contains one mol of carbon atoms. For the better calculating in the chemical reaction, we often use the mol as unit to describe the amount. Carbon is consists of carbon atoms. And the mol number is related to the mass of atoms. The molar mass of carbon is 12 g/mol. So the answer is 1 mol carbon atoms.
