Answer:

pH = 5.00

Explanation:

The pH is an unit of concentration widely used in chemistry and quality control of aqueous solutions. It serves to find the security of a product to human or pet consumption. Is defined as:

pH = -log [H+]

That means, the pH of a solution that is [H+] = 1.00x10⁻⁵M:

The atomic mass of helium-4 is 4.0026 amu. How many of each

umka21 [38]

Answer:

Protons: 2.

Electrons: 2.

Neutrons: 2.

Explanation:

Hello,

In this case, since an atom's atomic number is equal to the number of electrons, considering the electron configurations, taking into account that helium-4 is neither positively nor negatively charged, we can infer that the number of electrons equal the number of protons, which in this case are 2, due to the fact that is atomic number is 2.

Moreover, as helium-4's atomic number is 4 as a whole number, we compute the number of neutrons by using the shown below equation:

$Neutrons=mass\ number-atomic\ number\\\\Neutrons=4-2\\\\Neutrons=2$
