Sorry, I don’t believe in Jesus or god etc but thnx???
The question is asking to give and states the formulas for the mercury compound and base on my research and further investigation, the answer would be HgSO, Li2S2O3 and <span>(NH4)3PO4. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications </span>
Answer:

l(orbital number) 0 1 2 3
n l Er= n + l
7f 7 3 7+3 = 10
5d 5 2 5+2 = 7
3s 3 0 3 + 0 = 3
6p 6 1 6 + 1 = 7
4f 4 3 4 + 3 = 7
6d 6 2 6 + 2 = 8
Answer:
0.20moles
Explanation:
1 mole Na contains 23 g Na
23 g Na =1 mole of Na
1 g Na= 1/23 moles of Na
4.6 g Na= 1/23×4.6= 4.6/23=0.2 moles
Therefore 0.2 moles are present in 4.6 g of Na
Answer:
n = 2 moles (1 sig-fig)
Explanation:
Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...
pressure = P(atm) = 100atm
volume =V(liters) = 50L
gas constant = R = 0.08206L·atm/mol·K
temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K
PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)
∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).
