1 mol of CO2 is 44.01g/mol
So multiply that by 2 to get 2 mol of CO2, which is 88.02g
Answer:
D — All of them
Explanation:
The activation energy in a reaction is the minimum amount of energy required for a chemical reaction to take place. Since all the options are processes in a chemical reaction, D should be the answer.
if you go to a desert and your in the middle of nowhere you get thirsty and have no water and need to find water to drink so the sun is the reason it heats faster than water in the desert
Answer: 2.34 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.850 atm
= final pressure of gas = 1.50 atm
= initial volume of gas = 4.25 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Thus the final volume will be 2.34 L
First convert mL to L:
(500. mL)/(1000L) = .500L
Then convert molarity to moles:
(3.00M)(.500L) = 1.5mol NaCl
Then convert moles of NaCl to grams of NaCl by multiplying it by its molar mass:
(1.5mol NaCl)(58.44g/mol NaCl) = 87.66g NaCl are needed
