Answer:
I believe it's false because the atomic number is the number of protons in the nucleus of an atom.
Answer:
The hydroxide ions decrease.
Explanation:
I got it right on the quiz. This is what I saw. Read this, "Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7."
Hope this helps! Tell me if this is wrong just incase.
According to the Law of Conservation of Energy, energy is neither created nor destroyed. It is an entity that's always existing in the environment. It takes different forms of energy. Among the choices, the best answer would be letter B. Chemical energy. The chemical energy originates from the energy within the muscles that are dormant. Once used, this chemical energy is transformed into mechanical energy by the action of pushing his foot on the ground.
<span>The difference in pressure is equal to the pressure exerted by the displaced fluid.
Since the Pressure difference is equal, density of fluid is inversely proportional to the height of the column of displaced fluid => (Ď1)(h1) = (Ď2)(h2)
(13.6 g/ml)(753 - 724 mm Hg) = (0.822 g/ml)(h2)
h2 = (13.6 g/ml)(753 - 724 mm Hg) / (0.822 g/ml)
h2 = 480 mm</span>
