Answer: 60.7 g of will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is
is the limiting reagent as it limits the formation of product and is the excess reagent.
According to stoichiometry :
6 moles of produce = 4 moles of
Thus 2.68 moles of will produce= of
Mass of
Thus 60.7 g of will be formed by reactiong 60 L of hydrogen gas with an excess of
The correct answer is high temperature solids
Answer:
33.33 h
Explanation:
You know that
1 h = 60 min
If you divide both sides by 60 min, you get the conversion factor: 1 h/60 min = 1.
If you divide both sides by 1 h, you get the conversion factor: 1 = 60 min/1 h.
Both are conversion factors because they both equal one and multiplying a measurement by one does not change its value.
You choose the conversion factor that gives you the correct dimensions for your answer. It must have the correct dimensions on top (in the numerator),
Thus, to convert 2000 min to hours, you use the conversion factor with “h” on the top.
Answer: 120N
Explanation:
Given variables are:
force needed = ?
mass of object = 60 kg
acceleration = 2.0 m/s²
Since the magnitude of force depends on the mass of the object and the acceleration by which it moves.
i.e Force = mass x acceleration
Force = 60 kg x 2.0 m/s²
Force = 120 N
Thus, 120 Newton of force is needed to make 60 kg object accelerate at a rate of 2.0 m/s²
Magnesium(IV)dioxide
