Answer:
A free body diagram is used to calculate static and dynamic forces acting on an object. In other words, a free body diagram is the starting point to develop a mathematical model to find and calculate various forces acting on a body.
Explanation:
The volume occupied by the argon gas is, 1.44 L
Explanation :
To calculate the volume of argon gas we are using ideal gas equation:

where,
P = pressure of argon gas = 1528 torr = 2.010 atm
Conversion used : (1 atm = 760 torr)
V = volume of argon gas = ?
T = temperature of argon gas = 
R = gas constant = 0.0821 L.atm/mole.K
w = mass of argon gas = 4.24 g
M = molar mass of argon gas = 39.95 g/mole
Now put all the given values in the ideal gas equation, we get:



Therefore, the volume of occupied by argon gas is 1.44 L
Answer:
150.7815
Explanation:
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.
Answer:Carbon dioxide
Explanation:Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.
Next time you blow out a candle, think about what your breath is doing. Why do you think blowing on a candle flame makes it go out?
