Answer: The correct answer is Option A.

Explanation:

There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.

Protons carry positive charge, electrons carry negative charge and neutrons does not carry any charge.

Any neutral atom has an equal number of protons and electrons. An ion is formed when atom looses or gain electron.

If an atom gains electrons, it will have more number of electrons than protons. Thus, it will carry negative charge and form an anion.
If an atom looses electrons, it will have less number of electrons than protons. Thus, it will carry positive charge and forms a cation.

Thus, an ionized atom will always have unequal number of protons and electrons.

Hence, the correct answer is Option A.

A gas occupies a volume of 60 L at a temperature of 0.5 K. What will the volume be at 4 K?

Flauer [41]

Answer:

480 L

Explanation:

In order to solve this question, you should be familiar with gas laws. (I will attach a picture showing all of them under my answer.) In this question in particular, however, we only need Charles's Law because we're dealing with temperature and volume.

As we can see, Charles's Law is:

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

or, initial volume over initial temperature equals final volume over final temperature.

In this question, 60 L is our initial volume, and 0.5 K is our initial temperature (K being Kelvin). We are only given 4 K as our final temperature. We are asked to solve for the final volume. Let's set up the equation and solve for $V_{2}$ :

--------------------------------------------------------------------------------------------------------------

(60) / (0.5) = $V_{2}$ / (4)

↓

120 = $V_{2}$ / 4

×4 ×4

↓

$V_{2}$ = 480 L

--------------------------------------------------------------------------------------------------------------

There's our answer! Feel free to comment if you have any questions about my answer :)

How does the tendency of iron to rust depend on ph?

mojhsa [17]

The tendency of iron to rust depend on the Ph of solution

The formation of rust increases as the PH decreases. This led agent of rusting that is oxygen gets more positive as H+ ions increase which facilitate rusting. The lower the Ph level the quick the corrosion.

<h3>What is hexadecimal system?</h3>

Hexadecimal is an easy route for addressing twofold. It is vital to take note of that PCs don't utilize hexadecimal - it is utilized by people to abbreviate parallel to an all the more effectively reasonable structure. Hexadecimal Number System is generally utilized in Computer programming and Microprocessors. It is likewise useful to portray colors on pages. Every one of the three essential tones is addressed by two hexadecimal digits to make 255 potential qualities, hence bringing about in excess of 16 million potential tones. The primary benefit of utilizing Hexadecimal numbers is that it utilizes less memory to store more numbers, for instance it stores 256 numbers in two digits while decimal number stores 100 numbers in two digits. This number framework is likewise used to address Computer memory addresses.
