The balanced equation is:
Then proceed with the following equations.
The answer is
.
<span>Moles of solid copper used in reaction, using molar mass:
1 gram Cu @ 63.55 g/mol = 0.0157 moles Cu
(f) Moles of solid silver produced in reaction , using molar mass:
3.395g Ag @ 107.87 g/mol = 0.317 moles of Ag
Write the net ionic equation for the reaction between, using your mole values:
0.0157 Cu (s) & 0.317 Ag+ --> 0.0157 Cu+2 & 0.317 Ag (s)
Convert to whole number ratio, by dividing by the smaller :
0.0157 moles Cu / 0.057 = 1 mole Cu
0.317 moles Ag+ / 0.157 = 2 moles Ag
and rewrite the equation using the whole number ratio:
1 Cu (s) & 2 Ag+ --> 1 Cu+2 & 2 Ag (s)</span>
1) pOH(solution) = 6.
pOH + pH = 14.
pH = 14 - pOH.
pH = 14 - 6.
pH = 8.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.
This solution is basic, because pH value is greater than 7.
</span>2) [OH⁻] = 10∧(-pOH).
[OH⁻] = 10⁻⁶ M; equilibrium concentration of hydroxide ions.
Answer:
51:49 is the ratio of female participants to male participants.
Explanation:
Percentage of females in the race = 51 %
Percentage of males in the race = 100% - 51 % = 49%
Total participants in race = 400
Number of women participants =
Number of men participants =
Ratio of female participants to male participants :
Answer:
Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula CH₃OH. It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol.
Explanation:
