Find the number of moles of argon in 452 g of argon

Answers

Answer 1
Answer: no. of moles = given mass/atomic mass

= 452/40

= 11.3.

Thus, there are 11.3 moles
Answer 2
Answer: nó of moles =given mass/molar mass
no of moles=452/39.9
therefore no of moles=11.3moles

What is true at STP? 1) Temperature is 295 Kelvin.
2) One mole of gas occupies a volume of one liter.
3) Pressure is 1.0 atmosphere.
4) Volume is 2.4 liters

Answers

The correct answer for the question that is being presented above is this one: "3) Pressure is 1.0 atmosphere." STP stand for standard temperature and pressure. The values of STP are 22.4 liters, 1mole, 1.00 atmospheres, and 273 kelvin. Under these conditions, all gases behave ideally or the same.

Density is an example of what type of property?Intensive

Extensive

Chemical

Biological

Answers

Density is

Mass/Volume

both these are extensive because they change with different sizes and shapes of mass.

Density is a intensive property because the change had/had already been made so it is intensive. Density would be an intensive property.

Density is an intensive property, meaning it does not change as the amount of substance changes. It only depends on the type of substance, not its quantity.

Density is an example of an intensive property. Intensive properties don't change as the amount of the substance changes. They depend only on the nature of the substance, not its quantity. Other examples of intensive properties are boiling point, color, and temperature. On the other hand, extensive properties, such as volume and mass, change when the quantity of the substance changes.

Answers

Physical change.

Explanation:

  • This is a physical change.
  • The reason for escaping pops is the water caught internal parts it's bit.
  • Inside the event that the bit is warmed to a tall satisfactory temperature, this water will modify into steam. Due to the troublesome and for the preeminent parcel nonporous shell, the steam has no put to go, coming nearly in a buildup of weight internal parts the bit.
  • Once the weight gets tall satisfactory and the temperature comes to around 180 degrees Celsius (355 degrees Fahrenheit), the pops escape from the skillet or bursts and the popcorn is turned internal parts out.

Habitat ____________ splits ecosystems into pieces and makes populations more vulnerable to disturbances or climate change.A) diversification
B) extinction
C) fragmentation
D) unification

Answers

The correct answer is (C) fragmentation.

Habitat fragmentation is discontinuities in a organism's preferred ecosystem, causing disturbance in a population and ecosystem decay. Cause of fragmentation is geological processes and human activities like deforestation.  Habitat loss, which occur through the process of habitat fragmentation, is considered a greatest to species and biodiversity.
