In this question, XB3(aq) is an ionic compound which will have the releasing of 3 B⁻ ions ions in water for every molecule of XB3 that dissolves.
XB3(s) --> X+(aq) + 3 B⁻(aq)
[B⁻] = 0.22 mol XB3/1L × 3 mol B⁻ / 1 mol XB3 = 0.66 M
The answer to this question is [B⁻] = 0.66 M
Answer:
SnH4
Explanation:
Because the melting point of SnH4 is higher than CH4
Answer:
both are a number group of 12
Explanation:
dozen=12
AgNO₃ + NaCl = NaNO₃<span> + AgCl
1 mol AgNO</span>₃ --------------- 1 mole AgCl
15 mol AgNO₃ ------------- ? mole AgCl
moles AgCl = 15 x 1 / 1
moles AgCl = 15 / 1
<span>= </span>15 moles AgCl
