The answer to the question asked above is that in a Molecular Solid, the substance just dissolves into the solution when added to water but ionic solid does not.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
The molar mass of CO2 is 44 grams per mole.
165 grams / 44 grams per mole of CO2 = 3.75 moles CO2
Using Avogadro’s law where 1 mole of substance equals
6.023 x 10^23 molecules
3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2
We see that colour which is reflected by the surface because the object is made up of that colour.
<h3>What is the colour of lemon in white light?</h3>
A lemon in white light appears yellow to the human eye because yellow light is reflected by the lemon's surface while all other wavelengths of light are absorbed.
If the same lemon is placed into red light. It will appear to look red. This occurs because the red light will be transmitted by the lemon's surface and red light will be reflected to your eye.
So we can conclude that we see that colour which is reflected by the surface because the object is made up of that colour.

Question: Given the balanced equation representing a reaction:
2H2 + O2 ==>2H2O
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of oxygen?
(1) 18 g (3) 56 g
(2) 36 g (4) 72 g
Answer:
"72 gram" is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of oxygen
Explanation:
We will do stoichiometry in this kind of problem:
Therefore, the total mass of water formed is 72 g.
