<h2>
Time needed is 2545.45 seconds.</h2>
Explanation:
We know equation for power
Here we need to find time when for a 22 kW steam engine to do 5.6 × 10⁷ J of work.
So
Work = 5.6 × 10⁷ J
Power = 22 kW = 22 x 10³ W
Substituting
Time needed is 2545.45 seconds.
The base unit of length in the international system of units is the: meter (m)
<h3>Meter</h3>
The meter, ( symbol: m ) is the SI unit of length. It is derived by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s-1
<h3>International system of unit ( SI ) base units</h3>
The SI base units are the standard units of measurement defined which is defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of quantities:

Answer: the volume of the unknown mass
Explanation:
The other choices, molar masses of the reactants, the balanced chemical equation, and the molar masses of the product, are essential for the realization of stoichiometric calculations.
The balanced chemical equations tells the mole ratio of reactants (calcium carbonate) and products (calcium oxide and carbon dioxide).
The molar masses of reactants are used to convert between mass (grams) and moles.
The volume of the unknown mass is not needed when you are working only masses and moles since the relation is given by the molar masses. The volume is required when you are working with gas pressures, molarity contentrations or the information has to be worked from density measures.
