Answer:
You have to remember this memory aid, diagonals and all.
You have to keep a tight tally of the electrons you’ve used so far so you don’t go over the number of electrons in the element you’re working on.
You have to remember how many electrons fit into each subshell (s, p, d, f).
It takes a lot of time, especially when the element has more than 20 electrons.
Explanation:
K value of water is 1x 10^-14
Answer: 587.971086 ≈ 587.97
Explanation: one gram in moles of H3PO4 is 97.995181 so if you just have to multiply it by 6 to get the answer. I could be wrong.
What about understanding atoms and compounds?
Answer:
Explanation:
Since 1 mole of Fe reacted and 1 mole of Cu is produced.
Mass = molar mass × number of moles
Molar mass of Fe = 56 g/mol
Molar mass of Cu = 63.5 g/mol
Mass of Fe = 56 × 1
= 56 g
Mass of Cu = 63.5 × 1
= 63.5 g
Therefore, the statement is not correct.
