Answer:
V₂ = 453.125 mL
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 1.45 M
Final molarity = 0.0800 M
Final volume = ?
Solution:
Formula:
M₁V₁ = M₂V₂
Now we will put the values in formula.
1.45 M × 25.0 mL = 0.0800 M × V₂
V₂ = 1.45 M × 25.0 mL / 0.0800 M
V₂ = 36.25 M.mL / 0.0800 M
V₂ = 453.125 mL
Answer:When a single compound breaks down into two or more compounds or elements in a chemical reaction then it is known as decomposition reaction.
The chemical symbol for sodium carbonate is .
The decomposition of sodium carbonate is:
The decomposition of sodium bicarbonate, will result in the formation of sodium oxide, and carbon dioxide, .
Hence, carbon dioxide, will produce with sodium oxide, on decomposition of .
Explanation:Na2CO3 Na2O +CO2 CO2 is the answer
Answer: a. decrease from left to right in a period and increase down a group.
Explanation:
Atomic radius of an atom is defined as the total distance from the nucleus to the outermost shell of the atom.
As moving from left to right in a period, more and more electrons get added up in the same shell and the attraction between the last electron and nucleus increases, which results in the shrinkage of size of an atom. Thus, decreasing the atomic radii of the atom on moving towards right of the periodic table.
As moving from top to bottom in a group, there is an addition of shell around the nucleus and the outermost shell gets far away from the nucleus and hence, the distance between the nucleus and outermost shell increases. Thus, increasing the atomic radii of the atom.
