Answer:
the answer is mechanical energy
Explanation:
A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.
Answer:
The answer to your question is:
a) 3.87 mol of CO2
b) 14.63 mol of O2
Explanation:
2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(g)
a)
CO2 = ?
Butane 0.968 moles
From the balance equation 2 moles of butane ---------- 8 moles of CO2
0.968 moles of butane ------ x
x = (0.968 x 8) / 2
x = 3.87 moles of CO2
b)
moles O2 = ?
butane = 2.25 mol
From the balance equation
2 moles of butane ---------- 13 mol O2
2.25 mol ---------- x
x = (2.25 x 13) / 2
x = 14.63 mol of O2

4. According to the explanation given in one previous session, in this case we have the following reaction:
Zn + NO3- -> Zn(OH)42- + NH3
Our important informations to have in mind always first:
Single elements = 0 of oxidation number
Zn = 0
Oxygen = 2-
NO3- = overall charge must be -1, and we have 3 oxygens, so a -6 charge, therefore N must give a charge of +5
N (reactant) = 5+
Zn(OH)42- = overall charge -2, the charge for OH is always -1, we have 4 OH, therefore -4 of charge, to give -2 of overall, Zn must have a charge of +2
Zn (product) = 2+
OH = 1-
NH3 = 0
Now for the balancing of the reaction:
4 Zn + NO3- + 7 OH- + 6 H2O -> NH3 + 4 Zn(OH)42-
The nucleus of a atom contains the protons and the neutrons all most all of the atoms mass is weigh by the protons and the neurons.
