Answer : The limiting reactant is 
Explanation : Given,
Mass of 
= 30.0 g
Mass of = 75.0 g
Molar mass of = 44 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 1 mole of
So, 2.34 moles of react with 
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Therefore, the limiting reactant is
Answer:a law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature
Explanation:
A hot filtration should be used in the process of Crystallization.
<h3>What is Crystallization?</h3>
This is the conversion of a chemical in liquid form to a crystalline solid. The crystal formed are repeating three-dimensional pattern or lattice.
Hot filtration is used in the process of Crystallization of a solid which contains impurities that are insoluble in the crystallization solvent and also to remove highly colored impurities from a solid.

The heat is involved in the production of 5.0 mol of MgO is 180 Kj
calculation
2 Mg (s) +O2 → 2 MgO
From the equation above two moles of MgO is used therefore
72.3 is for 2 moles
that is 72.3 kj = 2moles
? = 5 moles
by cross multiplication
= 72.3 kj × 5/2 = 180 Kj
Answer:
108000 seconds
Explanation:
60 seconds in a minute. 60 minutes in an hour. 60 × 60 is 3600. 3600 × 30 is 108000
