A collection of monomers combines to form a polymer
Hope my answer helped! :D
<span> 52.0ml of 0.35M CH3COOH : 0.052 L(0.35M) = .0182 mol of CH3COOH.
</span>
<span>31.0ml of 0.40M NaOH : .031 L(0.40M) = .0124 mol of NaOH.
</span>
<span>After the reaction, .0124 Mol CH3COO- is generated and .058 mol CH3COOH is left un-reacted. The concentration would be 12.4/V and 5.8/V, respectively. Therefore:
</span>
<span>pH = -log([H+]) = -log(Ka*[CH3COOH]/[CH3COO-]) </span>
<span>= -log(1.8x10^-5*5.8/12.4) = 5.07</span>
Answer: There was a lower concentration of salt in the water than in the cells.
Explanation:
Osmosis is a process in which the solvent flow from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.
When the red blood cells are put in water that contained salt and the red blood cells burst after some time.
This means the solvent has moved from outside to inside the cell and this is possible only when the concentration of solute is high inside the cell than outside. That means the solution has low concentration of solute as compared to the cell and was a hypotonic solution.
It is a molecule because hydrogen is an element.
An element is made up of molecules
Stack effect? I'm not totally sure about this...
Explanation:
Large amount of tiny particles of water droplets, dust and smoke are present on a misty day. These tiny particles in the air scatter blue colour of white light passing through it. When this scattered light reaches our eyes, the smoke appears blue.
