Answer:

A. Electron clouds with a total of seven electrons

Explanation:

A neutral atom of nitrogen must have a total number of 7 electrons in its cloud.

This is the required number of electrons to bring nitrogen into its state of neutrality.

  • To maintain neutrality the number of protons and electrons in an atom must be equal.
  • A charge atom called an ion have either the proton or electron greater.
  • Neutrality is attained when the number of protons and electrons are the same.

There is a mixture of three gases. We know the total pressure is 2.50 atmosphere and the pressure of the oxygen and the nitrogen
Viktor [21]

Answer:

1.14 atm and 1.139 mol

Explanation:

The <em>total pressure</em> of the container is equal to the <u>sum of the partial pressure of the three gasses</u>:

  • P = Poxygen + Pnitrogen + Pcarbon dioxide
  • 2.50 atm = 0.52 + 0.84 + Pcarbon dioxide

Now we <u>solve for the pressure of carbon dioxide</u>:

  • Pcarbon dioxide = 1.14 atm

To c<u>alculate the number of CO₂ moles </u>we use <em>PV=nRT</em>:

  • P = 1.14 atm
  • V = 25.0 L
  • n = ?
  • R = 0.082 atm·L·mol⁻¹·K⁻¹
  • T = 32 °C ⇒ 32 + 273.16 = 305.16 K

1.14 atm * 25.0 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 305.16 K

  • n = 1.139 mol

Fill in the sentences below to explore the process by which a storm becomes a hurricane. some terms may be used more than once.
Reptile [31]

Answer:

The sentences which are made by the given sentences are as :

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.

Explanation:

Here in the question it has been mentioned to form the sentences with the given one:

  • Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
  • A tropical disturbance leads to an array of clouds which are disorganized    also there are thunderstorms with no rotation or little rotation with it.
  • When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
  • 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
  • When the storm reaches a tropical storm stage it gets its name.
  • All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.

These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
