Answer:
0.57 M
Explanation:
rate = change in concentration /time
Initial concentration of Cl2O5 = 1.16 M
Let the concentration of Cl2O5 after 5.70 seconds be y
rate = (1.16 - y)/5.7
The reaction follows a first order
Therefore, rate = ky = 0.184y
0.184y = (1.16 - y)/5.7
0.184y × 5.7 = 1.16 - y
1.0488y + y = 1.16
2.0488y = 1.16
y = 1.16/2.0488 = 0.57 M
Concentration of Cl2O5 after 5.70 seconds is 0.57 M

Explanation:
245 cm in inches: two hundred and forty-five cm are equal to 245/2.54 = 96.45669 inches.
Answer:
Moles = Mass / Mr
Moles = Concentration x Volume
Explanation:
Moles can be worked out in several ways depending on the information you are given. Some of the equations containing moles are:
Moles = Mass / Mr
Moles = Concentration x Volume
Answer:
Technology used to gather data enhances accuracy and allows scientists to analyze and quantify results of investigations. Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories
Explanation:
38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.
