- highest energy level for lithium
<u>A</u><u>N</u><u>S</u><u>W</u><u>E</u><u>R</u><u> </u><u>:</u>
- There are 2 electrons on the first energy level and 1 electron on the second. Explain that the first energy level can only have 2 electrons so the next electron in lithium is on the next (second) level. Explain that neon has 10 protons and 10 electrons.
The number of atoms in a molecule varies depending on the specific molecule formed. As a rule of thumb, a molecule must be composed of at least two atoms with no maximum amount of atoms as long as all the atoms in the molecule are bonded together somehow.
Did you ever find the answerr? if you did can I pls know ,Ty.
Answer:
144.08 g of H₂O
Explanation:
The balance chemical equation for the synthesis of water is as follow;
2 H₂ + O₂ → 2 H₂O
Step 1: <u>Find out moles of H₂O produced as;</u>
According to balance chemical equation,
1 mole of O₂ produced = 2 moles of H₂O
So,
4 moles of O₂ will produce = X moles of H₂O
Solving for X,
X = 4 mol × 2 mol / 1 mol
X = 8 moles of H₂O
Step 2: <u>Calculate Mass of H₂O as;</u>
Mass = Moles × M.Mass
Mass = 8 mol × 18.01 g/mol
Mass = 144.08 g of H₂O
