You need to use the ideal gas equation:
P is pressure (in atm or bar)
V is volume (in L)
n is the number of moles (in mol)
R is an experimentally determined ratio of about 0.82
T is the temperature (in Kelvin)
Note:
For all gases, you need to convert Celsius or Fahrenheit to Kelvin.Get V alone.
Plug in the values you have.
you get:
A fun fact: the gas used to fill up a balloon is Helium.
The appropriate answer is b. the lake effect. Buffalo is located on the north eastern shore of the Lake Erie. The high snowfall in this area is due to the fact that cold air masses will move across the expanse of the warmer lake water during the winter months. This warms the layer closest to the water causing it to pick up moisture from the lake. Once the moisture rises through the air mass it will freeze and form snow.
Answer:
The temperature to the nearest 0.5°C is 98.5°C
Answer:
12.5 moles
Explanation:
Given parameters:
Number of moles of FeS = 12.5moles
Unknown:
Number of moles of sulfur needed = ?
Solution:
We have to solve from the known to the unknown using a balanced chemical equation at first.
The balanced chemical equation for this reaction is:
Fe + S → FeS
The reaction is made possible when iron is heated in the presence of sulfur.
we see that;
1 mole of sulfur produced 1 mole of FeS
x mole of sulfur will produce 12.5moles of iron sulfide;
Therefore, 12.5 moles of sulfur will produce that given amount of iron sulfide.
