Answer:
pH of 4
Explanation:
Upon comparing a solution with a pH value of 4 and that having a pH of 7, you will realize that it has a pH difference of 3 although the concentration of ions of hydrogen having a pH of 7 is 1000 times greater than being at a pH of 4.
Answer:
-the reactants have more energy stored because you didn't get a great amount ( if any ) of energy released after the reaction was complete.
-Mg + O2 = MgO + energy

<h2>
Answer:</h2>
CH4 + 2O2 → CO2 + 2H2O
<h2>
Explanation:</h2>
10 grams of methane reacts with 40g of oxygen in the air. This means that mass from the oxygen in the air is also present in the carbon dioxide, so the mass can appear to increase, whereas in reality it is the mass of the oxygen that has caused the increase.
This reaction obeys the law of conservation of mass. Even though it may to appear so until balanced, all reactions follow the law.
