Answer:
See explanation and images attached
Explanation:
There are two compounds that could have molecular formula of C2H6O, they are ethanol and methoxy methane (trivial name: methyl ether). The structures of the two compounds are shown in the image attached as obtained from quora.
The boiling point of methoxymethane is -24.8°C while that of ethanol is about 78.5°C. The reason for the high boiling point of ethanol is the presence of intermolecular hydrogen bonding leading to a stronger intermolecular interaction compared to methoxymethane molecules held together only by very weak dispersion forces.
Answer:
Explanation:
We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.
M_r: 84.01
H₂SO4 + 2NaHCO₃ ⟶ Na₂SO₄ + 2CO₂ + 2H₂O
n/mol: 6
1. Use the molar ratio of NaHCO₃ to calculate the moles of NaHCO₃.
2. Use the molar mass of NaHCO₃ to calculate the mass of NaHCO₃.
You must use of NaHCO₃.
