Isotopes of the same element differ only in the number of neutrons an atom has. Its still the same element because the number of protons define an element. Just their neutrons and mass number is different.
Answer:
B
Explanation:
Presumably the system is closed (nothing can escape or enter).
A: You're cooling the container so it shouldn't explode.
C: If the container is Closed, the volume cannot increase or decrease.
D: is also impossible for the closed container reason.
B: The pressure has to decrease because the molecules are moving slower which decreases their velocity. If that happens the Force goes down.
B: Answer
Answer:
Molarity of solution = 0.9 M
Explanation:
Given data:
Moles of ZnCl₂ = 4.50 mol
Volume of solution = 200 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will convert the volume in L.
200 mL×1 L/1000 mL = 0.2L
M = 4.50 mol / 0.2 L
M = 0.9 M
9.04354 * 10^2
The “*” identifies as a multiplication sign. Hope this helps
I think it will stay the same.
