Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock solution = 10.0 M
= volume of stock solution = ?
= molarity of dilute solution = 0.50 M
= volume of dilute solution = 4.0 L
Therefore, the volume of 10.0 M solution needed to prepare 4.0 L of 0.50 M is 0.20 L
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
Answer:
The empirical formula=CHO. To explain it is C1H1O1 but we don't put the one that's why it is CHO

Answer : The number of free electrons per cubic meter for silver are
Explanation :
To calculate the number of free electrons per cubic meter for silver by using the following equation:
where,
= density of Ag =
= Avogadro's number =
= 107.87 g/mol
Now put all the given values in the above formula, we get:
conversion used :
Therefore, the number of free electrons per cubic meter for silver are
