the balanced equation for the combustion of ethane is as follows
2C₂H₆ + 7O₂ --> 4CO₂ + 6H₂O
molar ratio of C₂H₆ to H₂O is 2:6
this means that when 2 mol of C₂H₆ react 6 mol of H₂O are produced
for every 1 mol of C₂H₆ that reacts thrice the number of moles of H₂O are produced
therefore when 1.4 mol of C₂H₆ reacts - 3 x 1.4 = 4.2 mol of H₂O are produced
the answer is 4.2 mol
1 B2Br6 + 6 HNO3 = 2 B(NO3)3 + 6 HBr
Answer: A substance that produces hydroxide ions when placed in water is base.
Explanation:
Bases are the substance:
- Which gives negatively charged hydroxide() ions in aqueous solution.
- Which have pH value ranging from 7 to 14.
Where as acid gives positively charged hydronium ion() in aqueous solution.
C: Solution is another name for Homogenous mixture
