Answer would be B. CNS the central nervous system
Both chemical reaction rates and nuclear decay rates vary with the conditions of the change.
Answer : The limiting reactant is, carbon (C)
Explanation : Given,
Moles of = 2 moles
Moles of C = 5 moles
Now we have to calculate the limiting and excess reagent.
The given balanced chemical reaction is:
From the balanced reaction we conclude that
As, 3 mole of react with 1 mole of
So, 5 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.
Thus, the limiting reactant is, carbon (C)
Answer:
958 g is the mass of LiOH that can react with all the CO₂
Explanation:
CO₂(g) + 2 LiOH(s) → Li₂CO₃(aq) + H₂O
We think in the reaction:
1 mol of carbon dioxide can react with 2 moles of lithium hydroxide.
First of all, we convert the mass of our reactant to mol:
880 g . 1mol /44g = 20 moles
As ratio is 1:2, 20 moles of CO₂ will react with 40 moles of LiOH.
Let's determine the mass:
40 mol . 23.95 g /1mol = 958 g
2KClO₃ = 2KCl + 3O₂
n(KClO₃)=2 mol
n(O₂)=3/2 *n(KClO₃)
n(O₂)=1.5 *2 mol = 3 mol
3 moles of oxygen are produced
