Answer:

Mass = 24.4 g

Explanation:

Given data:

Mass of lithium nitride needed = ?

Volume of ammonia = 15.0 L

Solution:

Chemical equation:

Li₃N + 3H₂O   → NH₃ + 3LiOH

One mole = 22.414 L

We will compare the volume of lithium  nitride and ammonia.

                                NH₃             :            Li₃N

                              22.414           :              22.414

                               15.0              :               15.0  

Number of moles of lithium nitride:

PV = nRT

n = 1 atm ×15 L / 0.0821 atm.L / mol.K × 273 K

n = 15 /22.41 /mol

n =0.7

Mass of Lithium nitride:

Mass = number of moles × molar mass

Mass = 0.7 mol × 34.83 g/mol

Mass = 24.4 g

Which of the following will increase the volume of a gas?
Dmitry_Shevchenko [17]

Answer:

B. Decreasing the pressure applied to the gas molecules

Explanation:

According to Boyle's Law, the pressure of the gas is inversely proportional to the volume of the gas. So, the option B is correctly implied to it.

Other values such as Temperature, Number of molecules are inversely proportional to the volume of the gas.

Size of the gas molecules is negligible as compared to volume.

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.
