Lithium i think!!
hope this helps
Answer:
Mass of carbon dioxide = 7.48 g
Explanation:
Given data:
Mass of lithium carbonate = 12.5 g
Mass of carbon dioxide produced = ?
Solution:
Chemical equation:
Li₂CO₃ → Li₂O + CO₂
Number of moles of Li₂CO₃:
Number of moles = mass/ molar mass
Number of moles = 12.5 g /73.89 g/mol
Number of moles = 0.17 mol
Now we will compare the moles of Li₂CO₃ with CO₂.
Li₂CO₃ : CO₂
1 : 1
0.17 : 0.17
Mass of carbon dioxide:
Mass of carbon dioxide = number of moles × molar mass
Mass of carbon dioxide = 0.17 mol × 44 g/mol
Mass of carbon dioxide = 7.48 g
We know that density is a measure of mass per unit of volume:
Density = Mass / Volume
Therefore, we can calculate for the mass
Mass = Density * Volume
if the density of water is 1 g/cm^3:
Mass = Density * Volume
= (1 g/cm^3) * 94.60 cm^3
= 94.60 g
Answer:
The transformation was not added. See the attached file for the structure and the answer.
Explanation:
In the first reaction it is normal nucleophilic substitution reaction on the addition of hydrobromide. Hindu second reaction first the Hydroxide Ion attacks on the tertiary carbon because it is more reactive then the anion formed is further converted into carbonyl. And on the addition of methyl iodide we get the required product.
Answer:
False
Explanation:
The electrons are excited because:
1.- They posses more energy than the basal form, but this doesn´t mean that they can easily react, remember, the electrons are the outside part of an atom.
2.- By the time, this electrons are loosing their energy, that mean that they return to the basal form.
