A catalyst is a compound that accelerates a chemical reaction without getting used up in the process.
Un catalizador es un compuesto que acelera una reacción química sin ser agotado en el proceso.
The pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution.
<h3>What is the pH?</h3>
What we call the pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution. We are aware that we can use the relation [H+] [OH-] = 1 * 10^-14 to handle the enormity of this problem.
Now, let us go about solving the problems;
1. pH = -log(1 x 10-7) = 7
2. [H+]= 1 * 10^-14/ 1 x 10^-3
pH = -log( 1 * 10^-11)
pH = 11
3. pH = -log( 1 x 10^-2)
pH = 2
4. pH = -log( 1 x 10^-10)
pH = 10
5. [H+]= 1 * 10^-14/ 1 x 10^-8
[H+]= 1 * 10^-6
pH = 6

Answer:
The easiest way to find the number of protons, neutrons, and electrons for an element is to look at the element’s atomic number on the periodic table. That number is equal to the number of protons. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element.
Explanation:
15000g Lithium can be carried around with you.
Lithium is the lightest or is considered as the least dense metal with a density of 0.534 g/cm³ which is comparable to the density of a pine wood. More the amount of density, more amount of mass that particular element has. Density is the ratio of mass to volume, or it tells how much matter is packed in a given area. Palladium is a heavy metal with 12.02 g/cm³. Therefore, it has more density or more mass than lithium so it would definitely be difficult to carry around palladium than lithium. palladium has high mass to volume ratio than lithium.
Thus, with respect to palladium, Lithium being a light metal can be carried around easily.
