Answer: No reaction occurs
Explanation:.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
The complete ionic equation is;
The ions which are present on both the sides of the equation are are not involved in net ionic equation.
Hence, there is no net reaction.
The atomic mass of an element is the average relative mass of its atoms as compared with an atom of carbon-12 whose mass is taken as 12. In terms of percentages of different isotopes, the average atomic mass can be determined as follows: = ∑(
X
)/100. Where,
is the percentage abundance of isotope with atomic number
.
So, average atomic mass of neon = = 20.177 amu.
Answer:
<h2>The answer is 35 mL</h2>Explanation:
Density of a substance can be found by using the formula
From the question we are finding the amount of space the gas will occupy that's the volume of the gas
Making volume the subject we have
From the question
mass = 23.8 g/mL
Density = 0.68 g/mL
Substitute the values into the above formula and solve
That's
We have the final answer as
<h3>35 mL</h3>Hope this helps you
