Explanation:
1 miole of Fe2O is 6.22 × 10^-23
5mole of Fe2O = 5×6.22×10^-23
=31.1×10^-23
No because they are both made up of H2O molecules; they only have different physical properties, one is in liquid state while the other is in solid state
Hey
Matter can neither be created nor destroyed.
Explanation:
This is the law of conservation of matter (mass). One can prove this by performing a simple experiment at home.
Have a great day
Answer:
Correct option: <em>3</em>
Explanation:
A basic oxide is an oxide that reacts with water to give base or reacts with acid to form salt
eg:
Sodium oxide reacts with water to produce sodium hydroxide.
Magnesium oxide gives magnesium chloride on reaction with hydrochloric acid
An acidic oxide is an oxide that reacts with water to give acid and reacts with base to give salt.
eg: Carbon dioxide gives carbonic acid on reaction with water .
Sulfur dioxide gives sulfites when reacs reacts with bases.
An amphoteric oxide is an oxide which reacts with base as well acid and it shows because metal have multiple oxidation state and they can form oxide as well hydroxide
