Answer: The concentration of 
is 0.08 M.
Explanation:-
According to the neutralization law,
where,
= molarity of 
solution = 0.105 M
= volume of solution = 25 ml
= molarity of solution = ?
= volume of solution = 31.5 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of is 0.08 M.
3 ions are produced 1 Co2 and 2 No3-1. Hope this helps
Answer:
C
Explanation:
will silver wires conduct electricity better than copper wires ?
Answer:
The answer to your question is 33.4 ml
Explanation:
Data
volume 1 = V1 = 42 ml
temperature 1 = T1 = 20°C
temperature 2 = T2 = -60°C
Volume 2 = V2 = x
Process
1.- Convert celsius to kelvin
T1 = 20 + 273 = 293°K
T2 = -60 + 273 = 233°K
2.- Use the Charles' law to solve this problem
Solve for V2
V2 = 
3.- Substitution
V2 = 
4.- Simplification
V2 = 
5.- Result
V2 = 33.4ml
Explanation:
A metal with one valence electron is highly reactive compared to those with more than one electron.
Atoms including those of metals reacts in order attain a stable electronic configuration just like those of noble gases.
An atom with one valence electron have just one electron in its valence shell.
- Metals generally have large sizes.
- when the electron in this shell is lost, the metal atom can then attain stability.
- therefore, such atom will quickly want to combine with any other willing to accept the electron so that they can be stable.
- Those with more than one electron will find it difficult to lose them.
- It requires huge energy to remove such electrons compared to the ones with only one valence electron.
