What statement is true about isotopes?
ipn [44]

Answer:

D. THEY HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS BUT DIFFERENT NUMBERS OF NEUTRONS.

Explanation:

Isotopy is the phenomenon that explains the various variants of an element having different number of neutrons but the same number of protons and electrons.

Isotopes are variants of a particular chemical element that possesses the same number of proton or atomic number but different mass number. The atomic number of an element is the number of protons and electrons contained by the element while the mass number is the sum total of the number of protons and neutrons in the nucleus of the elements.

Examples of isotopes are the hydrogen atom, chlorine element and so on.

Hydrogen has three isotopes which are hydrogen H, Deuterium and Tritium. Chlorine has two isotopes which are chlorine 35 and chlorine 37.

So the true options about isotopes is that they possess the same number of protons and electrons but different numbers of neutrins.

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.
