Answer:
650 grams
Explanation:
Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is
Gram-formula mass of g/mol
So, mass of 1 mole of acelylene is 26 grams
Therefore, mass of 25 moles of acelylene=25x26=650 grams
Hence, the mass of 25 moles of acelylene is 650 grams
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
