Answer:
Carbon = 1s2 2s2 2p2 group= 14 period = 2
Explanation:
group can be taken from the electronic configuration here it is 2s2 2p2 so it should belongs to 4A or 14
Answer:
Decomposition
Explanation:
H2CO3 Breaks down to H2O and CO2
Using the general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
(105*220)/275 = (P₂*95)/310
(105*220)*310/275 = P₂*95
(105*220*310)/(275*95) = P₂
274.11 = P₂
P₂ = 274.11 kPa
New Pressure = 274.11 kPa
2NaOH(aq) + H2SO4(aq) => Na2SO4(s) + 2H2O(l)
This is a neutralization reaction.
Answer:
20 oxygen atoms
Explanation:
Li2SO4 has 4 oxygen atoms, so if there are 5 of that compound then there will be 20 oxygen atoms.
