Answer:
383.90K
Explanation:
P1 = 851mmHg
T1 = 330K
T2 = ?
P2 = 990mmHg
To solve for P2, we have to use pressure law which states that the pressure of a fixed mass of fixed is directly proportional to its temperature provided that volume remains constant
Mathematically,
P = kT, k = P/T
P1 / T1 = P2 / T2 = P3 / T3 =.......=Pn / Tn
P1 / T1 = P2 / T2
T2 = (P2 × T1) / P1
T2 = (990 × 330) / 851
T2 = 383.90K
The final temperature of the gas is 383.90K
Mercator and conic projections are different because conic projections have a cone/triangle shape and Mercator projections have a cylindrical look to them. They are both the same because they show the world. However, the world is viewed from very different perspectives. For example, a Mercator projection is from the point of view of a bird and the conic is from a view from space.
Chromium (Cr): 2, 8, 8, 6
Copper (Cu): 2, 8, 8, 11
Chromium+2 (Cr+2): 2, 8, 8, 4 (if the ion retains a positive charge then the amount of electrons will decrease)
Copper+2 (Cu+2): 2, 8, 8, 9
Manganese+2 (Mn+2): 2, 8, 8, 5
