Answer:
The molar mass of the gas is 44.19 g/mol
Explanation:
Amount of sample of gas = m = 13.5 g
Volume occupied by the gas = V = 5.10 L
Pressure of the gas = P = 149.83 KPa
1 KPa = 0.00986 atm
P = 
Assuming M g/mol to be the molar mass of the gas
Assuming the gas is behaving as an ideal gas

The molar mass of gas is 44.19 g/mol
The option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag.
<h3>What is a cell?</h3>
A cell is the basic and functional unit of life. Every living organism is made up of one or more cells.
However, a plant cell is morphologically different from an animal cell. One of the major differences is that a plant cell posseses a cell wall that protects the cell.
According to this question, Julia made a model of a cell in a clear plastic zipper bag. She used a marble for the nucleus and pinto beans for mitochondria.
Therefore, the option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag which will represent the cell wall.

1.3 sec is the answer because you take the distance and divid by the rate
Answer:
the uses of exothermic reactions are:
1) lighting of stove
2) self heating cans
3) hand warmers
4) in some case exothermic process can be used to cook food such as rice (by adding calcium oxide to water heat is evolved and it helps to cook food )
