Answer:
Which of the following pairs lists a substance that can neutralize Ca(OH)2 and the salt that would be produced from the reaction?
HCl and CaCl2
HClO and CaHClO
H2O and Ca(OH)3
H3PO4 and Ca(PO3)2
Explanation:
The given substance is Ca(OH)2 which is a base.
To neutralise a base an acid is required.
Among the given options,
HCl and H3PO4 are the acids.
The salts foremd when calcium hydroxide reacts with the respective acids are CaCl2 and Ca3(PO4)2.
But among the given options, only the forst option that is
HCl and CaCl2 shows the correct formulas.
Hence, the answer is first option.
The completed and balanced equation is:
<span>Hg(N<span>O3</span><span>)2</span>+N<span>a2</span>Cr<span>O4</span>=HgCr<span>O4</span>+2Na(N<span>O3</span>)

They are forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions.
Aluminum is an example of an element
Answer:
5.30x10²³g
Explanation:
A mole can be understood as an amount of something.
One mole of eggs are 6.022x10²³ eggs
One mole of atoms are 6.022x10²³ atoms
One mole of molecules are 6.022x10²³ molecules
And 1 mole of M&M are 6.022x10²³ M&M. As 1 M&M weighs 0.88g, 1 mole will weigh:
0.88g*6.022x10²³ =
<h3>5.30x10²³g</h3>
