Answer:
The atom that loses the electrons becomes a positively charged ion, while the one that gains them becomes a negatively charged ion
The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
Answer: Option (A) is the correct answer.
Explanation:
Force acting on a dam is as follows.
F =
.......... (1)
Now, when we double the depth then it means H is increasing 2 times and then the above relation will be as follows.
F' = 
F' =
........... (2)
Now, dividing equation (1) by equation (2) as follows.
=
Cancelling the common terms we get the following.
=
4F = F'
Thus, we can conclude that if doubled the depth of the dam the hydrostatic force will be 4F.
Answer:
6.66 mL
Explanation:
The increase in the volume is due to the addition of the iron whose volume can be calculated as:
Using,
Density = Mass / Volume
Given that:
Density of Iron = 7.87 g/cm³
Mass of iron = 52.4 g
Thus, volume is:
Volume = Mass / Density = 52.4 / 7.87 cm³ = 6.66 cm³
Also, 1 cm³ = 1 mL
<u>The rise in the volume = 6.66 mL</u>
