Answer:

50 gram of MgS contains =21.56 gram of Mg

Explanation:

Molecular mass of MgS is 56.37 g/mol.

Atomic mass of 1 mole Mg is 24.305

Therefore 56.37 gram of MgS contains 24.305 gram of Mg

1 gram of MgS contains $\frac{24.305}{56.37}$ gram of Mg

50 gram of MgS contains $\frac{24.305}{56.37}$ ×50 gram of Mg

=21.56 gram of Mg

Find [cu2+] in a solution saturated with cu4(oh)6(so4) if [oh − ] is fixed at 2.3 ✕ 10−6 m. note that cu4(oh)6(so4) gives 1 mol

ki77a [65]

<span>

</span> $Cu_4(OH)_6(SO_4)$
<span>
You have OH- conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is 4 : 6 = 2:3

So, for 2.3 ✕ 10−6 m OH-
[Cu2+] = $\frac{2}{3} \times 2.3 \times 10^{-6}$

$= 1.53 \times 10^{-6}

If an atom of Oxygen (8 protons, 8 neutrons, and 8 electrons) gains two electrons, what is the charge of the ion formed?

Alexxx [7]

Answer:

It becomes negative

Explanation:

protons carry a positive charge

neutrons carry a neutral charge

electrons carry a negative charge

if we add 2 more electrons, the charge of the ion becomes negative

thank you.
