If I have a +2 oxidation number do I give up or accept electrons?​

Chemistry
1 answer:
sveticcg [70]3 years ago
5 0

Answer:

Give up 2 electrons.

Explanation:

Is this ever a good question!!!

Electrons have a minus charge

Protons have a plus charge.

You need to understand it thoroughly.  I used to explain it this way.

Suppose the protons and electrons are playing a game and the electrons commit a foul that leaves them with 2 men short.

That means there are 2 unguarded plus's around. The result is that the minuses have lost two men who are in the sin bin. (I watch a lot of hockey).

So a +2 means that the electrons have lost two of their players to penalties.

Put in the vocabulary of your question, you give up 2 electrons.

The molar solubility of ag2s is 1.26 × 10-16 m in pure water. calculate the ksp for ag2s.
MAXImum [283]
Answer is: Ksp for silver sulfide is 8.00·10⁻⁴⁸.
Reaction of dissociation: Ag₂S(s) → 2Ag⁺(aq) + S²⁻(aq)<span>.
</span>s(Ag₂S) = s(S²⁻) = 1.26·10⁻¹⁶ M.
s(Ag⁺) = 2s(Ag₂S) = 2.52·10⁻¹⁶ M; equilibrium concentration of silver cations.
Ksp = s(Ag⁺)² · s(S²⁻).
Ksp = (2.52·10⁻¹⁶ M)² · 1.26·10⁻¹⁶ M.
Ksp = 6.35·10⁻³² M² · 1.26·10⁻¹⁶ M.
Ksp = 8.00·10⁻⁴⁸ M³.

If a plant produces 8.46 mol C6H12O6, how many moles of H2O are needed?
Ierofanga [76]

Answer:

50.76 mol H2O.

Explanation:

The photosynthesis follows the equation:

6CO2 + 6H2O ---> C6H12O6 + 6O2

This means that 6 mol of H2O are needed to obtain 1 mol of C6H12O6 (see the numbers that precedes every molecule to know how many mols are in game).

So we can say that:

1 mol C6H12O6 --------- 6 mol H2O

8.46 mol C6H12O6 -----x= 8.46 x 6 : 1 = 50.76 mol H20

Silicon has 2 isotopes, Silicon-28 with an abundance of 90% and Silicon-30 with an abundance of 10%. Find the AAM for Silicon.
JulsSmile [24]

Answer:

RAM

RAM = (mass \: of \:  ^{28} Si \:  \times \%abundance) + (mass \: of \:  ^{30} Si \:  \times \%abundance) \\ RAM = (28 \times 90\%) + (30 \times 10\%) \\ RAM = 25.2 + 3 \\ RAM = 28.2
