Oduvanchick [21]3 years ago
4 0

Answer:

6 atoms total; 4 H^+ atoms, 2 O^2- atoms

Explanation:

2(H2O)

2 * 2H atoms = 4 H atoms

2 * 1 O atom = 2 O atoms

4+2 = 6 total

000 atm of dry nitrogen, placed in a container having a pinhole opening in its side, leaks from the container 3.55 times faster
Ivanshal [37]
We will assume that the question is discussing 1.000 atm of N₂ initially. The question is discussing diffusion rates of two gases and asks us to identify the species. We can use Graham's Law to attempt this problem with the following formula:

Rate₁/Rate₂ = sqrt(M₂/M₁)

We are told that the N₂ is 3.55 times as fast as the unknown species, so rate 1 = 3.55 and rate 2 = 1. We know the molecular weight of N₂ as 28 g/mol. Now we can use the equation above to solve for the molecular weight of the unknown, M₂:

3.55/1 = sqrt(M2/28)
(3.55)² = M₂/28
M₂ = 28 (3.55)₂
M₂ = 353 g/mol

The unknown compound has a molecular mass of roughly 353 g/mol and this is very close to the molecular mass of UF₆ which is 352.02 g/mol. Therefore, it is likely that the unknown gas is UF₆.

How do silica levels differ between the North Atlantic and North Pacific oceans
frez [133]

Answer:

The highest biogenic silica accumulation rates in this area are observed in the South Atlantic, with values as large as 53 cm. kyr−1 during the last 18,000 yr. Further, extensive biogenic silica accumulation has been recorded in the deep-sea sediments of the Bering Sea, Sea of Okhotsk, and Subarctic North Pacific.
