Answer:
The limiting reactant in a reaction is the first reactant to be completely converted to products.
Explanation:
When we perform a reaction, it is not easy to measure the exact amount of the two reagents to make sure that both of them react completely. That's why typically we have a limiting reagent and a reagent in excess.
The limiting reagent is the one which determines the maximum amount of product formed, as when it's used up, the reaction stops and cannot proceed further, since the other reagent doesn't have anything to react with.
Simply speaking, the limiting reactant in a reaction is the first reactant to be completely converted to products.
The limiting reagent provides the information about the amount of the product formed, as opposed to the reagent in excess which doesn't provide any valuable information.
Answer:
c
Explanation:
Denisty= Mass/ Volume, therefore
Volume= Mass/Density
a) 100/2= 50ml
b) 240/0.8= 300ml
c)100/5= 20ml √
d) 140/3.5=40ml
Personally the first thing i do, is expand the number

Answer:
Oxygen cycle, along with the carbon cycle and nitrogen cycle plays an essential role in the existence of life on the earth. The oxygen cycle is a biological process which helps in maintaining the oxygen level by moving through three main spheres of the earth which are:
Explanation:
The atmosphere is the layer of gases presents above the earth’s surface. The sum of Earth’s ecosystems makes a biosphere. Lithosphere is the solid outer section along with the earth’s crust and it is the largest reservoir of oxygen.
