Answer:
an atom is the smallest particle of matter
a compound is a substance that has two or more atoms and element is the opposite of compound.
molecule is........,...............hope this helps
A - Endothermic. This is because it absorbs heat rather than releases it.
B - Exothermic. It's releasing heat which in turn makes the beaker hot.
C - Endothermic. The Ammonium Chloride is absorbing the heat away from the beaker.
D - Exothermic. To produce nuclear energy, it needs to release heat.
E - Endothermic. The hydrogen and oxygen atoms are absorbing the heat given off from the electric current.
F - Exothermic. It is producing heat or releasing heat.
Exothermic is the losing, release, or production of heat. Endothermic is the exact opposite; it is the storing of heat.

Answer:
Combustion.
Explanation:
When burning a hydrocarbon (CxHy) with Oxygen the products are Carbon Dioxide and Water.
Answer:
<h2>0.38 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.38 moles</h3>
Hope this helps you
The two chemical formulas which will correctly complete the table for lithium fluoride are: A. HF, LiOH.
<h3>What is a chemical reaction?</h3>
A chemical reaction can be defined as a chemical process that involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, in order to produce a new chemical compound while new bonds are formed.
This ultimately implies that, chemical bonds between atoms of a chemical element are broken and then new bonds are formed in all chemical reactions.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction can be defined as a type of chemical reaction between an acid and a base, which typically leads to the formation of an ionic compound (salt) and water as end products as shown below:
LiOH(aq) + HF(aq) → LiF(s) + H₂O(l)
In this context, we can infer and logically deduce that the two chemical formulas which will correctly complete the table for lithium fluoride are HF and LiOH.
