Answer:
The second sample will produce 1563 grams of fluorine (F2)
Explanation:
The reaction will be MgF2 → Mg + F2
The stoichiometry ratio of MgF2 and F2 is 1 : 1.
That means for 1 mole of MgF2 consumed there is 1 mole of F2 produced.
The first sample produces 2.15 kg of magnesium and 3.36 kg of fluorine
The second sample produced 1 kg of magnesium and x kg of fluorine
This we can show in the following equation =
2.15kg / 3.36 kg = 1kg / x
2.15/3.36 = 0.63988
0.63988 = 1/ x
x= 1/0.63988 = 1.563 kg
1.563kg = 1563 grams
The second sample will produce 1563 grams of fluorine (F2)
Answer:
Outside air
Nose
Lungs
Bloodstream
Cell
Explanation:
We breathe in oxygen from the outside air in through our nose and it travels to our lungs. Inside our lungs, we have Avioli's that diffuse oxygen into our bloodstream and the bloodstream helps the oxygen travel into our cells.
Hope this helps :)
Answer:
Trapping-bring (the ball) under control with the feet or other part of the body on receiving it.
Heading-shoot or pass (the ball) with the head.
Dribbling-take (the ball) forward past opponents with slight touches of the feet
This is if your talking about soccer
Explanation:
Throwing-propel (something) with force through the air by a movement of the arm and hand.
Answer:
Warmer air can hold more water vapor than colder air.
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object (body).
On the other hand, humidity refers to the concentration (amount) of water vapor that is present in the air. It is high when there's a lot of water vapor in the air and low when the level of water vapor is small.
The relationship between air temperature and humidity is that warmer air can hold more water vapor than colder air because as the air cools, its molecules move closer together while the molecules move farther apart as the air become hot.
Additionally, at constant humidity, relative humidity is inversely proportional to temperature i.e as the temperature decreases, relative humidity increases.
