To have a PH of 3, it means that the substance must be acidic since a PH of less than 7 less means that the tested substance is acidic. If the PH is greater than 7 then it will be a base or the opposite of acidic. PH of a solution can be tested with litmus paper ie qualitatively to see if it is an acid or a base. Aof an example of a base is NaOH sodium hydroxide and of an acid is H2SO4 or sulfuric acid.
Answer:
9 moles of NaNO3 is obtained
Explanation:
The balanced chemical reaction equation for the reaction is;
Al(NO3)3 + 3NaCl-------> 3NaNO3 + AlCl3
Now, we have to determine the limiting reactant. The limiting reactant yields the least amount of NaNO3.
1 mole of Al(NO3)3 yields 3 moles of NaNO3
4 moles of Al(NO3)3 yields 4 * 3/1 = 12 moles of NaNO3
Also,
3 moles of NaCl yields 3 moles of NaNO3
9 moles of NaCl yields 9 * 3/3 = 9 moles of NaNO3
Hence, NaCl is the limiting reactant and 9 moles of NaNO3 is obtained.
So first we need to know what the formulas are:
Methane:
Oxygen:
Carbon Dioxide:
Water:
So then we follow the equation as specified in the question. Note that it does not need to be balanced, as the question states it wants the unbalanced equation:
→
This is the preliminary, unbalanced equation with the correct chemical formulas.
