For an arrangement of electrons to be nonpolar in a molecule they need to have equal electron charges.
Answer:
Protons and Electrons
Explanation:
Protons are positively charged particles in an atom and electrons are negatively charged. These charges cancel out to make a neutral atom. For example, Carbon has 6 protons (+6) and 6 electrons (-6). 6 - 6 is 0, making it neutral.
0.841 micrograms is the answer.
If you have any questions, let me know.
The balanced equation for the reaction is as follows;
Li₂O + H₂O ---> 2LiOH
Stoichiometry of Li₂O to H₂O is 1:1
Mass of Li₂O reacted - 18.9 g
Number of Li₂O moles reacted - 18.9 g / 30 g/mol = 0.63 mol
An equivalent amount of moles of water have reacted - 0.63 mol
mass of water required - 0.63 mol x 18 g/mol = 11.34 g
A mass of 11.34 g of water is required
