Fahrenheit is a temperature scale
The main difference between the two is that emission spectrum has different colored lines in the spectrum, an absorption spectrum has dark colored lines in the spectrum.
<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>
There are 236 grams in 5.9 mole of NaOH.

Answer:
a) 0.25 g b) 0.01542 g
Explanation:
Half life of Po-218 = 3.04 minutes
initial mass = 1 g
after 3.04 minutes it will remain 0.5 g
after another 3.04 minutes it will remain 0.25 g
After 6 minutes it will remain approx 0.25 g
B) after another 3.04 minutes it will remain 0.125 g
after another 3.04 minutes it will remain 0.0625 g
after another 3.04 minutes it will remain 0.03125 g
after another 3.04 minutes it will remain 0.015625 g
After 18 minutes it will remain approx 0.01542 g
