<h3><u>Answer;</u></h3>
They are made up of elements.
<h3><u>Explanation;</u></h3>
- An atom is the smallest particle of matter that still retains the property of the element.
- Two or more atoms combine to form elements or compounds. Elements are formed by two or more similar atoms, while compounds are formed by two or more different elements.
- Atoms are made up of subatomic particles; protons, electrons and neutrons. Electrons are negatively charged, protons are positively charged while neutrons have no charge.
Missing part of the question. Please add which are the process to be classified.
Answer:
A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
Answer:
2.29 g of N2
Explanation:
We have to start with the <u>chemical reaction</u>:

The next step is to <u>balance the reaction</u>:

We can continue with the <u>mol calculation</u> using the molar mass of
(65 g/mol), so:

Now, with the<u> molar ratio</u> between
and
we can <u>calculate the moles</u> of
(2:3), so:
With the molar mass of
we can <u>calculate the grams</u>:
