What happens when a gas is heated in a closed metal container

Chemistry
2 answers:
postnew [5]3 years ago

When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.

Answer:

Hope this helps!!

Explanation:

Molecules of a gas move randomly. In a sealed container they exert a force when they collide with the container walls and this applies a pressure to the container. If the cylinders heat up enough, their pressure will increase and they will explode.

How many grams of sodium chloride are present in a 0.75 M solution with a volume of 500.0 milliliters?
LUCKY_DIMON [66]
The units for molarity is moles of solute per liter of solution which means if you multiply the molarity of a solution by its volume you get how many moles of solute are in the solution. (0.75Mx0.5L=0.375mol NaCl) Then you can multiply the moles of sodium chloride (0.375 mol) by its molar mass (58.45 g/mol) to get 21.92g of sodium chloride. That means there is 21.92 grams of sodium chloride in 500mL of 0.75M solution. I hope this helps. Let me know if anything is unclear.

TRUE OR FALSE :Normal cells will not divide unless the nutrients they require are already presen True False
Diano4ka-milaya [45]

Answer:

False

Explanation:

Cell division is a primary procedure by all cells. This process in the life cycle of cells ensures that new cells (daughter cells) are produced. The two major process are; meiosis and mitosis.

Normal cells would divide if the nutrients required are not present, since water is the main nutrient required. But in some cases, the division process may lead to an effect on one or both daughter cells. This effect is called mutation, thereby mutated cells may be produced.
