Answer:
all these are physical properties except release of heat so it's probably heat energy given off
Given :
Number of molecules of .
To Find :
How many moles are in given number of molecules.
Solution :
We know, in 1 moles of any element/compound contains at atoms/molecules.
So, number of moles in molecules are :
Therefore, number of moles are 8.97 .
Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution () and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.
This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.
As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution
Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
Answer:
Explanation:
Liquids have the medium energy level of the three state. They have enough energy for the molecules to break free from their solid lattice but not enough to separate from being in groups of molecules, they move around slowly and randomly in groups, with a moderate level of kinetic energy to power them.
