Activation energy?? The energy needed to start a chemical reaction is called activation energy
Answer:
11.2 M
Explanation:
Given data:
Number of moles = 6.7 mol
Volume of solution = 0.6 L
Concentration /Molarity = ?
Solution:
Molarity:
It is number of moles of solute in to per kg or litters of solution. It can be calculated by the following formula.
Molarity = number of moles / Volume in L
Now we will put the values in formula.
Molarity = 6.7 mol / 0.6 L
Molarity = 11.2 mol/L
Molarity = 11.2 M
1-Option A. Current model will be revised.
2-Option D. Nucleus
3-<span>Option B. </span>Counting the no. of protons.
Answer:
The electrons where in motion
I’m pretty sure it’s in a group (column) of the period table. Hope this helps :)))
