Answer:
one mole of carbon would have a mass of 12.011 grams
Answer:
65.8mL of water and 184.2mL of the 95% EtOH stock solution must be added.
Explanation:
To solve this question we need to find hoy many times the 95% EtOH must be diluted to obtain a 70% EtOH solution. That is:
95% / 70% = 1.357 times the solution must be diluted.
If we want to make 250mL of the diluted solution, the amount of 95% that must be added is:
250mL / 1.357 times =
184.2mL of the 95% solution must be added
And of water:
250mL - 184.2mL = 65.8mL of water
Answer: <em>Running water, even at a trickle, helps prevent pipes from freezing. If you decide to use fuel-burning equipment, such as a kerosene heater, ensure it is vented to outside and kept clear of any vents. Keep garage doors closed if there are water supply lines in the garage.</em>
Explanation:
Answer:
The concentration of nitrate ion is 0.033 M.
Explanation:
1 mole of = 3 mole
Let = 3y
then according to above reaction,
= y
= 0.10 M (given)
= ?
3y = 0.10 M
y = 0.033 M
So ,concentration of = y = 0.033 M
Answer:
CH4+4Cl2=CCl4+4HCI
