Answer:
Answer is in the explanation
Explanation:
All acids that dissociates completely in water are considered strong acids. In the same way, bases that dissociates completely in water are strong bases. All hydroxides made from alkali metals and heavier alkali earth metals are strong bases.
HNO3 dissociates completely in water: STRONG ACID.
HCl dissociates completely in water. STRONG ACID.
NaCl is a salt. Neither a strong acid nor a strong base.
Ca(OH)2. Heavy alkaline earth metal. STRONG BASE.
CH3COOH an acid that doesn't dissociate completely in water. Neither a strong acid nor a strong base.
CH3NH2 is a weak base that doesn't dissociate completely in water. Neither a strong acid nor a strong base.
CH3OH. Methanol is an alcohol. Neither a strong acid nor a strong base.
HF is a weak acid; doesn't dissociate completely in water. Neither a strong acid nor a strong base.
RbOH. Is an hydroxide made from alkali metal. STRONG BASE.
I’m pretty sure its b or a
Answer:
Option B.
Explanation:
As any reaction of combustion, the O₂ is a reactant and the products are CO₂ and H₂O. Combustion reaction for ethane is:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
So 2 moles of ethane react with 7 moles of oxygen to make 4 moles of dioxide and 6 moles of water.
Then 2 moles of ethane will produce 4 moles of CO₂
CH4 + O2 = CO2 + H2O - Chemical Equation Balancer.
