Okay
Mr (H2O)= 18g
therefore moles of H2O
is 720.8/18= 40.04mol
the ratio of H2 to O2 to H2O is
2 : 1 : 2
so moles of H2 is same as H2O here
H2= 40.04moles
moles of O2 is half
so 40.04 x 0.5
20.02moles
grams of O2 is
its moles into Mr of O2
that's 20.02 x 32 = 640.64g
Answer:
The reaction rate would decrease
Explanation:
The equation for the Haber process is given by;
N₂(g) + 3H₂(g) ⇆ 2NH₃(g)
- The reaction occurs at a temperature of 500°C
- Therefore, the forward reaction requires a temperature of 500°C.
- According to Le Chatelier's principle, if a factor affecting equilibrium is altered, the equilibrium will shift in the direction that counteracts the effect causing it.
- In this case, decreasing the temperature to 100°C will lower the rate of the forward reaction.
- Consequently, less ammonia gas will be produced as the reverse reaction is favored.
The number that will be multiplied by 588 to get one's weight in Newtons is 2.5 considering that the mass of the individual is 60kg.
<h3>How to calculate weight?</h3>
Weight is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).
The weight of an object can be calculated by multiplying the mass of the object by acceleration due to gravity of the location.
According to this question, we would consider an individual with a mass of 60kg. The acceleration due to gravity on Jupiter is 24.5 m/s².
Weight = 60kg × 24.5 m/s² = 1470N
This means that the number to be multiplied by 588 to get weight of 1470N is 2.5.

Answer : The molarity of the solution is, 1.1 M LiCl
Explanation : Given,
Mass of 
= 32 g
Volume of solution = 655 mL
Molar mass of = 42.4 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the molarity of the solution is, 1.1 M LiCl
