Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
2 moles of C₂H₆ 6 moles of H₂O
1.4 moles of C₂H₆ x
x = (1.4 x 6) / 2
x = 8.4/2
x = 4.2 moles of H₂O"
The preservation technique that
attempts to remove moisture is dehydration or drying of foods. Many types of
food such as meat, fish are preserved for an unlimited period by removing the
moisture. This way, the growth of microorganisms in the food is hindered. Dehydration
