The water molecule is a polar molecule which would mean that there is an uneven distribution of charges. Each molecule of water has partial positive and partial negative end. The partial positive charges is found in the H atoms while the partial negative is at the O atom. This is due to the the unequal sharing of the electrons.
Drexel’s it then u get the answer
CO2 is released by yeast during fermentation of the starches in the flour. It is considered fermentation (anaerobic respiration) as the bread is airtight and is kept in airtight environments meaning oxygen cannot take part in the reaction.<span />
Answer:
a. Sally did not take account the atoms of the compounds, because she only summed Al + O and in the oxide, we have 2 mol of Al and 3 mol of O
b. The conversion factor that Jacob did, was wrong.
Moles must be divided by moles, so they can be cancelled. The correct conversion factor is:
9.45 mol . 102 g / 1 mol = 963.9 g
Explanation:
Al₂O₃ → Aluminum oxide
We determine the molar mass:
Molar mass Al . 2 + Molar mass O . 3
27 g/mol . 2 + 16 g/mol . 3 = 102 g/mol
