Balanced equation: 2Na(s) + Cl₂(g) ---> 2NaCl(s)
when we have STP conditions, we can use this conversion: 1 mol = 22.4 L
first, we have to convert grams to molecules using the molar mass, and then use mole to mole ratio from the balanced equation.
molar mass of Na= 23.0 g/mol
ratio: 2 mol Na= 1 mol Cl₂ (based on coefficients of balanced equation)
calculations:
Explanation:
First, we will calculate fuel consumption is as follows.
![372 L/min \times 1000 ml/L \times 0.730 g/ml \times \frac{1}{60} min/s](https://tex.z-dn.net/?f=372%20L%2Fmin%20%5Ctimes%201000%20ml%2FL%20%5Ctimes%200.730%20g%2Fml%20%5Ctimes%20%5Cfrac%7B1%7D%7B60%7D%20min%2Fs)
= 4526 g/s
Now, we will calculate the power as follows.
Power = Fuel consumption rate × -enthalpy of combustion
= ![4526 g/s \times -26.5 kJ/g](https://tex.z-dn.net/?f=4526%20g%2Fs%20%5Ctimes%20-26.5%20kJ%2Fg)
=
kW
Thus, we can conclude that maximum power (in units of kilowatts) that can be produced by this spacecraft is
kW.
The liver cells produce proteins to avoid blood clotting. They also break down old or damaged blood cells.
H• •Be• •H --> H:Be:H
Since there are 4 valence electrons in total, Beryllium has 2 and Hydrogen has 2. You would put the Be in the middle because there is only 1 of them.
