Answer:
so 0.15 moles X 22.4 dm3/mole=3.36 dm3. Next we find the moles of hexane combusted, and then the moles of CO2. Finally, we find the volume of CO2 using the fact that at STP, 1 mole of gas = 22.4 dm3.
Answer:
Overall reaction equation is:
Cl2(g) + CHCl3(g) --> HCl(g) + CCl4(g)
The intermediates are Cl(g), CCl3(g).
Rate law= ka^1/2 c
Explanation:
This reaction is a non elementary reaction. A non elementary reaction is one that does not take place in a single reactive encounter. In other words, the reaction is comprised of many steps.
The overall reaction equation is the sum of all the reaction steps after all intermediates have been cancelled out. The rate law is obtained from the slowest step in the reaction sequence.
B.) "Distillation" <span>would work best to separate a mixture of liquids with different boiling points

Decreasing the activation energy needed for the reaction.
Answer:
See detailed explanation.
Explanation:
Hello,
In this case, since the International Prototype of the Kilogram (IPK) is an object made of a platinum-iridium alloy that was used to define the magnitude of the mass of the kilogram as it weights 2.2 pounds or approximately 1 kg, yet it was replaced by a new definition of the kilogram based on physical constants. In such a way, it is important because it was the base for the current understanding of what a kilogram is and its relationship with other mass measurements.
Thus, if would not have existed, we were not be able to design and use balances or mass-measuring equipment in order to provide a reliable measure of the real mass of an object.
Best regards.
