Answer:
a. Ethanol.
b. 4.21 mL H2O.
c. 87.8%
Explanation:
Hello,
- For the limiting reactant, the available amount of ethanol is less than the ideal amount of ethanol that would react with the given amount of oxygen, that's why it is the limiting one.
- You will find the calculations in the attached picture; take into account that the molecular mass of water is 18 g/mol and ethanol 46 g/mol.
- The percent yield is allowed to be computed in terms of volume as well, because the relationships are conserved.
Best regards!
Answer:
5.59x10^-3 moles
Explanation:
The balanced equation for the reaction is given below:
HCl + KOH —> KCl + H2O
Now we can obtain the number of mole of HCl required to produce 5.59x10^-3 moles of KCl as follow:
From the balanced equation above, 1 mole of HCl produced 1 mole of KCl.
Therefore, 5.59x10^-3 moles of HCl will also produce 5.59x10^-3 moles of KCl.
From the illustration made above, we can see evidently that 5.59x10^-3 moles of HCl is required to produce 5.59x10^-3 moles of KCl
Answer:
Shanika should move the orange coaster car to point A and move the green coaster car to point D. This movement will result in the largest increase in potential energy because the farther the carts are from the magnet, the faster they will travel to get to the magnetic force. Therefore, they will create a big increase in potential energy.

I'm not sure if this is correct but I hope this helps :)
Answer:
r² x h
Explanation:
A can is cylindrical in nature. Using the formula of the volume of the can, we can find this unknown volume.
The volume of cylinder is given as:
Volume of a cylinder = Area x height
Volume of a cylinder = r² x h
Therefore density of the can;
Density =
