<span>B. S⁰(s) + 2H⁺ + 2e⁻ –--> H2S⁰(g)

by mass: 1 S  and 2 H ----> 2 H and 1S  True.
by charge : 0 +(2*(+1)) + 2*(-1) = 0, 0+2-2=0, 0 = 0  True.</span>

The following equation(option B) is balanced for charge and mass

A. S(s) + 2H+ → H2S(g) + 2e–


B. S(s) + 2H+  + 2e–  →  H2S(g)


C. S(s) + 2e- →H2S(g)


D. S(s) + 2H+→ H2S(g)


S(s) + 2H+  + 2e–  →  H2S(g)



here S is one on either sides

H is two on either sides, hence mass is balanced.


And charge is also balanced,


as  2H+ has +2 charge

and 2e- has -2 charge,thus

total charge on left side is +2-2 = 0

and charge on right side is also zero here or no charge on either sides.

To what volume should you dilute 50.0 ml of 12 m hno3 solution to obtain a 0.100 m hno3 solution?
bearhunter [10]

Answer:

The answer is "6L"

Explanation:

Formula:

\bold{C_1 \times V_1 = C_2 \times V_2 }\\\\V_2= \frac{C_1\times V_1}{C_2}

Values:

\to C_1= 12 \ m\\\to V_1= 50 \ ml\\\to C_2= 0.100 \ m\\\\\\V_2= \frac{12 \times 50 }{0.100}

   = \frac{12 \times 50 }{0.100}\\\\= \frac{12 \times 50 \times 1000}{100}\\\\= \frac{600 \times 1000}{100}\\\\= 600 \times 10\\\\=6000 \ ml\\= 6 \ L
