Answer;
= 7.59 × 10^-4 M
Explanation;
The molar concentration of [H3O+] in a cola with a pH of 3.120 can be calculated by:
[H3O+]=10−pH
[H3O+]=10−3.120
[H3O+]=7.59×10−4M
Ingestion of large amounts of phosphoric acid found in cola can upset the body's regulation of bone metabolism and reduce the absorption of calcium from the diet. For this reason, people who are at risk of developing osteoporosis are often advised not to drink much cola.
Answer:
Energy
Explanation:
Nuclear fusion is the process of combining atoms to make heavier atoms. This releases a huge amount of energy and it is what stars like our sun use to create energy.
Answer:
d) Ni < Co < Fe < Zn < Al
Explanation:
electronegativity of Aluminium 1.6
electronegativity of Zinc 1.7
electronegativity of iron 1. 83
electronegativity of Cobalt 1.88
electronegativity of Nickel 1.91
As the electronegativity of aluminium is lower as compared to other, so it will have high tendency to easily lose electron and that is why Aluminium is more reactive than the other mentioned
Use blue litmus paper. This is an indicator that can safely determine whether it is a base or an acid by changing color in response to the substance. This color indicates whether it is an acid or a base. Refer to the pH scale to see if the substance is basic or acidic.
Answer:
Electron
Explanation:
The answer would be the electron because it is constantly moving so its location cannot be accurately determined
