c. the answer is radioactive elements are useful for dating materials
I think the answer is research and development.
Answer:
His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... The amount of the change in velocity is determined by Newton's second law of motion.
Explanation:
Explanation:
It is given that mass of ascorbic acid = 0.287 g
As molar mass of ascorbic acid is 176.12 g/mol. Hence, calculate its number of moles as follows.
moles ascorbic acid =
moles ascorbic acid =
= mol
So, moles of =
=
= mol
Therefore, moles NaOH required = moles
moles NaOH required = mol
Now, we will calculate the volume of NaOH as follows.
volume NaOH =
volume NaOH =
= 0.0652 L
or, = 65.2 mL (as 1 L = 1000 ml)
Thus, we can conclude that the volume of NaOH required is 65.2 ml.
This is an example of a solution. You make a solution by using water as a solvent in which ammonia dissolves.
