It mean it consisted of 1 g of lead and 0.077 g of O2.
divide these numbers by molar mas.
1/82=0.012 Pb /0.004 = 3
0.077/16= 0.004 O /0.004 =1
Pb3O
Answer:
373.88 torr
Explanation:
P1 = 350 torr
T1 = 20°C = (20 + 273.15)K = 293.15K
P2 = ?
T2 = 40°C = (40 + 273.15)K = 313.15K
From pressure law,
Pressure of a given mass of gas is directly proportional to its temperature.
P = KT
K = P / T
P1 / T1 = P2 / T2
Solve for P2
P2 = (P1 * T2) / T1
P2 = (350 * 313.15) / 293.15
P2 = 109602.5 / 293.15
P2 = 373.878 torr
P2 = 373.88 torr
The new pressure of the gas would be 373.88 torr.
The correct answer to your question would be B) Loess, or <span>Aeolian deposits , reasoning to your question is because, loess is a german word but in english means loss or loose. So given that clay and small particles that are not combined together are loose particles. moves freely. Hope this helps you out.

Answer:
1. The correct option is;
c. maintains charge balance in the cell
2. The correct option is;
c. +3.272 V
Explanation:
The aqueous solution in a galvanic cell is the electrolyte which is a ionic solution containing that permits the transfer of ions between the separated compartment of the galvanic cell such that the overall system is electrically neutral
Therefore, the aqueous solution maintains the charge balance in the cell
2. Here we have;
B₂ + 2e⁻ → 2B⁻ Ecell = 0.662 V
A⁺ + 1e⁻ → A Ecell = -1.305 V
Hence for the overall reaction, we have;
2A + B₂ → 2AB gives;
(0.662) - 2×(-1.305) = +3.272 V.
