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.

The answer is; C
These lines that join areas of equal pressure during an air system are called isobars. The black lines in the diagram below are the isobars. They are good indicators of the strength of these systems. The innermost closed lines indicate the positions of relative maxima (high-pressure areas) and minima (low-pressure areas) in the pressure field.
To calculate the number of moles we will use Avogadro's number, which relates the number of molecules contained in a mole of any substance, the relationship between moles and molecules is as follows:
In the statement we are given the molecules with 3 significant figures, therefore the answer must also have 3 significant figures. So the answer will be: In 5.25x10^29molecules are 8.72x10^5 mol of sucrose
Answer:
C
Explanation:
The plate 'float' on top of the liquid magma. There are convection currents that circulate through the magma, and the techtonic plates are moved along with the magma.
