Answer:
An acid is a substance that when dissolved in water produces hydroxonium ion as the only positive ion in water
Explanation:
HCL +H20=H3O + CL
Glycogen is formed by the loss of water molecules along the length of the polymer chain as the glucose molecules are joined together.
<h3>
How is glycogen formed?</h3>
Glycogen is formed by a process known as condensation polymerization. This involves the loss of -OH from one glucose molecule and the loss of H from another glucose molecule as the chain is formed.
Hence, glycogen is formed by the loss of water molecules along the length of the polymer chain as the glucose molecules are joined together.

Explanation:
Let us take the volume of block is x.
Since, the block is floating this means that it is in equilibrium. Formula to calculate net force will be as follows.
![F_{net} = Buoyancy force(F_{b}) - weight force(w)](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20Buoyancy%20force%28F_%7Bb%7D%29%20-%20weight%20force%28w%29)
Also, buoyancy force
= (volume submerged in water × density of water) + (volume in oil × density of oil)
=
=
g
As, W = V × density of graphite × g
It is given that density of graphite is
or 2160
.
So, W = 2160 V g
= (0.592 V \rho + 408 V) g - 2160 V g = 0
= 1752
= 2959.46
or 2.959
is the density of oil.
It is given that mass of flask is 124.8 g.
Mass of 35.3
oil =
104.7 g
Hence, in second weighing total mass will be calculated as follows.
(124.8 + 104.7) g
= 229.27 g
Thus, we can conclude that in the second weighing mass is 229.27 g.
