Answer:
the fastest would be gas, liquid would be in the middle and solid would be the slowest
Explanation:
9. all you have to do find the atomic mass of each atom in the periodic table.
Na is 23.0
O= 16.0
molecular mass of Na2O= 2x23.0 + 16.0= 62.0 g/mol
10. this is the description of an acid
<u>Answer:</u> The net acid-base reaction of the anion formed and water is written below.
<u>Explanation:</u>
Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.
The chemical equation for the ionization of NaClO follows:
Now, the anion formed which is reacts with water to form conjugate acid.
The chemical equation for the reaction of anion with water follows:
Hence, the net acid-base reaction of the anion formed and water is written above.
Answer:
Option (c) is correct.
Explanation:
The density of a substance is 0.83 g/mL.
We know that the density of water is 1 g/mL
It means the density of the substance is less that that of density of water. If the density of substance is less that water then it will float on water's surface.
Hence, the correct option is (c) "The substance will FLOAT because it's density is SMALLER than water".
The mass of an electron is:
0.00054386734 or 9.1 x <span>10^-31 kg</span><span>.
