Explanation:
It is given that volume of is 300 mL and molarity is 0.200 M.
Volume of NaCl is 200 mL and molarity is 0.050 M.
The chemical reaction will be as follows.
for is given as .
As, molarity is number of moles present in liter of solution.
Hence, moles of (aq) will be calculated as follows.
moles of (aq) =
= 0.06 mol
=
= 0.120 M
Mole of =
= 0.010 M
Now, Q =
=
=
As, Q < hence, there will be no formation of precipitate.
Answer:
A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors.

Answer:
The balanced equation is given below:
CH4 + 2O2 → 2H2O + CO2
The coefficient of O2 and CO2 are 2 and 1 respectively.
Explanation:
CH4 + O2 → 2H2O + CO2
The above equation can be balanced as follow:
There are a total of 4 atoms of O on the right side and 2 atoms on the left. It can be balance by putting 2 in front of O2 as shown below:
CH4 + 2O2 → 2H2O + CO2
Now we can see that the equation is balanced.
Therefore, the coefficient of O2 and CO2 are 2 and 1 respectively.
