The planet Gallifrey has two naturally occurring isotopes of chlorine. Chlorine-35 has an isotopic abundance of 45.89% and a mas

s of 34.9689 amu. Chlorine-37 has an isotopic abundance of 54.11% and a mass of 36.9659 amu.
Calculate the average atomic mass of chlorine on planet Gallifrey.

Answer:

36.05 amu

Explanation:

Given data

Isotope       Mass (m)               Abundance (ab)

³⁵Cl              34.9689 amu        45.89% (0.4589)

³⁷Cl              36.9659 amu        54.11% (0.5411)

We can calculate the average atomic mass (am) of chlorine on planet Gallifrey using the following expression.

am = ∑ mi × abi

am = 34.9689 amu × 0.4589 + 36.9659 amu × 0.5411

am = 36.05 amu

When two or more refrigerant are mixed what must be done with the mixture
german
Refrigerants are chemical mixtures composed of several substances. During the HVAC cycle, <span>refrigerants can usually exist in several states.
These substances have very dangerous and destructive effects on the environment.

Based on this, if two or mire </span><span>refrigerants are mixed together, the mixture must be recovered into a separate tank and sent to the specialized facility to destroy it. 
The destruction of the mixture should only be done by experts in specialized facilities.

Solids, liquids, and gases are the three most commonly accepted phases of matter. Explain the properties of each phase, includin
nasty-shy [4]

Answer:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another.  They have least kinetic energy.  For example : chair

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.  They have more kinetic energy than solids but less than that of gases. For example : oil

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.  They have most kinetic energy. For example : Hydrogen

If the moxie tank has an initial pressure of 50 atm in the winter what will be the pressure in summer
elena55 [62]

The pressure of the Moxie's tank in the summer will be 110.5 atm.

The correct option is C.

<h3>What is pressure law?</h3>

According to the pressure law, if the volume remains constant, for a given mass of gas, the pressure applied to the container's sidewalls is directly proportional to the gas's absolute temperature.

<h3>Briefing:</h3>

This law can be expressed mathematically as

P₁/T₁ = P₂/T₂

where

P₁ is the starting pressure.

The final pressure is P₂.

The starting temperature is T₁

The final temperature is T₂

The pressure of the gas increases as its temperature does.

As a result, since summertime temperatures are higher than wintertime temperatures, the pressure within the Moxie's tank will be higher than 50 atm throughout the summer.

The complete question is -

If the Moxie's tank has an initial pressure of 50 atm in the winter, what will be point the pressure in the summer?

A. 5.88 atm

B. 22.6 atm

C. 110.5 atm
