The limiting reagent when 5 g of NaOH and 4.4 g CO₂ allowed to react will be NaOH
<h3>What is Limiting reagent ?</h3>
The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
Given chemical equation in balanced form ;
2NaOH(s) + CO₂(g) → Na₂CO₃(s) + H₂O(l).
According to the Chemical equation ;
- The limiting reagent when 5 g of NaOH and 4.4 g CO₂ allowed to react will be NaOH
If 44 g CO₂ requires 80 g of NaOH, therefore, 4.4 g CO₂ will require atleast 8 g of NaOH.
But the available quantity is 5 g NaOH. thus, NaOH is the Limiting reagent.
- 6.625 g of Na₂CO₃ are expected to be produced 5.0 g of NaOH and 4.4 g of CO₂ are allowed to react
As 80 g NaOH produces 106 g of Na₂CO₃.
Therefore 5 g NaoH will produce ;
106 / 80 x 5 = 6.625 g

Answer:
16
Explanation:
number of electrons should also be 16.
Yes becuase it says it maintains its velocity if it is moving or at rest
Answer:
a) acidic; [H+] = 10^-2.5 = 3 x 10^-3
b) basic; [H+] = 10^-11.7 = 2 x 10^-12
c) slightly acidic (almost neutral); [H+] = 10^-6.8 = 1.6 x 10^-7
d) acidic; [H+] = 10^-3.31 = 4.9 x 10^-4
Explanation:
pH < 7 is acidic; pH > 7 is basic; pH = 7 is neutral
[H+] = 10^-pH
