It would be fatal for all.The ones on the side of sun would get everything but the ones farer than the sun wouldn't survive.There would be day forever on one side and night forever on other.
Answer:
False.
Explanation:
Fusion reactions are not yet commercially viable because they require extremely high energies to initiate and sustain a reaction.
Explanation:
Let us assume that the given data is as follows.
mass of barium acetate = 2.19 g
volume = 150 ml = 0.150 L (as 1 L = 1000 ml)
concentration of the aqueous solution = 0.10 M
Therefore, the reaction equation will be as follows.

Hence, moles of
=
.......... (1)
As, No. of moles =
Hence, moles of
will be calculated as follows.
No. of moles =
=
(molar mass of
is 255.415 g/mol)
= 
Moles of
= 
= 0.01715 mol
Hence, final molarity will be as follows.
Molarity = 
= 
= 0.114 M
Thus, we can conclude that final molarity of barium cation in the solution is 0.114 M.
Answer:
C. copper.
Explanation:
- The atom which loses electrons (its oxidation sate be more positive) is the atom that is oxidized.
- While, the atom which gains electrons (its oxidation sate be more negative) is the atom that is reduced.
It is oxidation sate is changed from (+5) in the reactants (NO₃⁻) to (+4) in the products (NO₂). N gains 1 electron
So, it is reduced.
It is oxidation sate is the same (-2) in the reactants (NO₃⁻) and (-2) in the products (NO₂).
<em>So, it is neither be oxidized nor reduced.</em>
<em></em>
It is oxidation sate is changed (0) in the reactants (Cu) to (+2) in the products (Cu²⁺). Cu loses 2 electrons.
<em>So, it is oxidized.</em>
<em></em>
It is oxidation sate is the same (+1) in the reactants (H⁺) and (+1) in the products (H₂O).
<em>So, it is neither be oxidized nor reduced.</em>
