What is the mass of 5.00 moles of KaS04?
Varvara68 [4.7K]

Answer: D

Explanation:

I assume you meant \text{K}_{2}\text{SO}_{4}.

  • The atomic mass of potassium is 39.0983 g/mol.
  • The atomic mass of sulfur is 32.065 g/mol.
  • The atomic mass of oxygen is 15.9994 g/mol.

So, the formula mass of potassium sulfate is 2(39.0983)+32.065+4(15.9994)=174.2592 g/mol.

So, 5.00 moles have a mass of (5.00)(174.2592), which is about <u>870 g</u>

Greenhouse gases released from the burning of fossil fuels are responsible for global warming.

<h3>What is the atmosphere?</h3>

The atmosphere is the region of region of the planet above its surface area where gases envelop the planet.

Based on the effect of greenhouse gases on global warming;

  • Planet A has a higher surface temperature due to the higher amount of carbon dioxide in the atmosphere since carbon dioxide is a greenhouse gas.
  • Methane is the main constituent of natural gas. Humans increase the contribute to increase in methane gas by raising cattle,
  • Pollutants come from both natural sources and human activities.
  • Sulfur Dioxide is produced by the combustion of fuels in automobiles. Once in the atmosphere, it combine with water to form acid precipitation.
  • Nitrogen and oxygen do not contribute to the greenhouse effect because they are  made up of 2 atom molecules that are bound tightly so they CANNOT vibrate to absorb energy.
  • Greenhouse gases contribute to global warming by absorbing infrared energy that reflects off Earth's surface and reemitting the energy in all directions. This keeps the infrared energy close to the Earth's surface.
  • Most of the greenhouse gases produced come from burning fossil fuels in factories, ships, cars, trains.

Therefore, pollutants such as greenhouse gases are responsible for global warming.

1. Review the information in the table below. Use the information to calculate rate of how many sandwiches are made in a 10-minu
PilotLPTM [1.2K]

Answer:

The answer to your question is given below.

Explanation:

Rate is simply defined as quantity per unit time. Mathematically it is represented as:

Rate = Quantity /time

Thus, we can obtain the rate as follow:

1. Quantity = 20 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 20/10

Rate = 2 sandwich per mins

2. Quantity = 30 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 30/10

Rate = 3 sandwich per mins

3. Quantity = 40 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 40/10

Rate = 4 sandwich per mins

4. Quantity = 50 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 50/10

Rate = 5 sandwich per mins

Thus, the complete table is given as follow:

Quantity >> Unit of measure >> Rate

10 >>>>>>> 10 min >>>>>>>>>> 1

20 >>>>>>> 10 min >>>>>>>>>> 2

30 >>>>>>> 10 min >>>>>>>>>> 3

40 >>>>>>> 10 min >>>>>>>>>> 4

50 >>>>>>> 10 min >>>>>>>>>> 5
