C.
Their radiation facilitates nuclear fusion in young stars.
B. Fossil
Why? Well skeleton seems like another answer BUT the definition of a fossil is an imprint of an organism on rock.
Example: A dinosaur presses it’s foot in dirt and it leaves a footprint or ‘fossil’ behind
No, the dilution does not change the number of moles dissolved
Explanation:
We can see that,
The molarity of the solution was 0.50 M
The volume of the solution is 10 ml.
No of moles of the solute was= volume * concentration
= 10 X 10^-3* 0.50
= 5*10^-3 moles
When the solution is diluted from 10 ml to 100ml, the molarity or concentration changes but number of moles remains constant.
The molarity of 100 ml solution will be
c=n/V
= 5*10^-3*/100*10^-3
= 0.05
when the solution is diluted to 100ml from 10 ml molarity changes from 0.5M TO 0.05 M
Answer:
44.95408163 kg
44.95 kg (2 decimal places)
Explanation:
Weight=Mass*Gravity
440.55=m*9.8
Make m the subject
M=440.55/9.8
M= 44.95 kg
I believe it is the scientific definition of work, as work = force x distance
