The Answer is Noble gases.
It's consequential to note that helium has only two electrons so it does not have the equal electron dot structure as the other noble gases. Electron dot structure displays the number of valence electrons (electrons in the highest energy level) for an atom.
Answer:
L2 add a for NAL add a 2 then for the first NA2 put a 4 and then the second NA2 put a 2 and it should be good
Explanation:
Answer:
2molH2O:1molO2
=2molH2÷1molO2
=1molO2
=1molO2÷2molH2O
Explanation:
I have tried My out most ☺️
1) State the equation that represents the chemical reaction
P2O5 + 3H2O → 2H3PO4
2) State the molar ratios: 1 mol P2O5 : 3 mol H2O : 2 mol H3PO4
3) Use the proportions 3molH2O / 2 mol H3PO4
0.729 mol H3PO4 * [ 3 mol H2O / 2 mol H3PO4] = 1.094 mol H2O
Answer: 1.094 mol of water
