Atomic mass = number of protons + number of neutrons
= 10 + 8 = 18
In short, Your Answer would be Option C
Hope this helps!
A proton contains 2 up quark 1 down quark and gluons which the 3 quarks exchange. Now since there is only 1 option I would choose gluon. But it's up to you.
Answer:
k
Explanation:
They must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.
The percentage yield of copper = 76%
<h3>Further explanation</h3>
Given
6.5g of Zinc
The mass of Copper: 4.8 g
Required
The percentage yield of copper
Solution
Reaction
Zn+CuSO₄⇒Cu+ZnSO₄
mol Zn :
= mass : Ar Zn
= 6.5 g : 65,38 g/mol
= 0.0994
From the equation, mol ratio of Zn : Cu = 1 : 1, so mol Cu = 0.0994
Mass Cu (theoretical) :
= mol x Ar Cu
= 0.0994 x 63,546
= 6.316 g
%yield = (actual/theoretical) x 100%
%yield = (4.8/6.316) x 100%
%yield = 76%
