Answer:
Lithium does form a peroxide as well as an oxide on burning in air and I suspect the low temperature reaction with air forms a significant amount of peroxide.
Li2O is the formula for <span> lithium oxide</span>
Answer:
A Li2O
Explanation:
Li has a 1+ charge and O has a 2- charge so to balance the charges there needs to be 2 Li for every 1 O
Answer:
123 g/mol
Explanation:
Let's consider the neutralization reaction.
H₂Z(aq) + 2 NaOH(aq) → Na₂Z(aq) + 2 H₂O(ℓ)
The moles of NaOH that reacted are:
The molar ratio of H₂Z to NaOH is 1:2. The moles of H₂Z that reacted are:
The molar mass of H₂Z is:
the reaction is HF + NaOH which leads to NaF
