Answer:

Explanation:
Hello!
In this case, for the reaction:

In such a way, via the rate proportions, that is written considering the stoichiometric coefficients, we obtain:

Whereas the reactants, CO and H2 have negative stoichiometric coefficients; therefore the rate of disappearance of hydrogen gas is related to the rate of appearance of methanol as shown below:

Which means that the rate of disappearance of hydrogen gas is negative and the rate of appearance of methanol is positive.

Continent drifts
Explanation:
The use of fossil evidences to support the correlation of land masses that are presently not together can suggests that continents do move and land masses can change position.
This was one of the earliest prove suggest by Alfred Wegener to back up his theory of continental drift.
- Since fossils are evidence of prehisotric life, a place originally together should have the same fossil contents.
- When they become separated, the fossil contents in their lithology should match.

Answer:
Moles of boron trifluoride gas that were collected = 11.6 mol
Mass of boron trifluoride gas that were collected = 787 g
Explanation:
Given that:
Temperature = 2.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (2.0 + 273.15) K = 275.15 K
V = 15.0 L
Pressure = 0.130 atm
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
Applying the equation as:
0.130 atm × 15.0 L = n ×0.0821 L atm/ K mol × 275.15 K
⇒n = 11.6 mol
<u>Thus, Moles of boron trifluoride gas that were collected = 11.6 mol
</u>
Molar mass of boron trifluoride gas = 67.82 g/mol
The formula for the calculation of moles is shown below:
Thus,
<u>Mass of boron trifluoride gas that were collected = 787 g</u>
Your answer would be 499,867,705 square kilometers
