 Magnesium is a metal. As such it is not possible to determine its pH. What you can do is calculate the pH of a solution of a magnesium salt such as Mg(OH)2 or MgCl2 etc, etc. The pH will depend on the concentration of the salt, the type of salt etc.<span>

Mrrafil [7]

Answer:

B

Explanation:

We are talking about the periodic table in which elements where put under different rows and columns according to their atomic number (number of protons) in ascendant order.

In rows or periods we can find trends in some properties like atomic radius, electronegativity, etc...). So they are not similar in size. Option A is a false statement.

Also, they were organized in groups or columns according to their similar electronic configuration and chemical properties (like noble gases, halogens, etc...) This means option B is the correct statement.

What is the relationship between temperature and reaction rate?​
Alecsey [184]

Explanation:

Temperature has a direct relationship with reaction rate. The higher the temperature the faster the rate of reaction of a system.

  • For every 10°C rise in temperature above the room temperature, it has been found that reaction rates becomes double or triple.
  • When the temperature of a reacting system increases, the kinetic energy of each of the reacting particles increases.
  • The frequency of collision and effective collision also increases per unit of time.
  • Many of the reacting particles will acquire an energy greater than or equal to the activation energy of the reaction.
