You may normally expect a slow reaction if a low activation energy is required.

Answer:

Explanation:

Hello,

In this case, chlorine's percent composition is given by the shown below formula:

Whereas accounts for the number of chlorine atoms into the NaCl, for chlorine's atomic mass and for sodium chloride's molar mass, therefore, the percent composition of chlorine turns out:

Best regards.

Answer;

(4) the total number of protons and the total number of electrons in the atom

Explanation;

-Atomic number is the number of protons in the nucleus of an atom. An atom is made up of energy shells and the central nucleus. The energy shells contains electrons that are negatively charged while the nucleus contains protons (positively charged) and neutrons (neutral).

-In a neutral atom, the number of protons and electrons are equal, thus the atomic number would indicate the number of electron and protons in an atom. The sum of protons and neutrons on the other hand gives the mass number.

The layers of the Earth, from lowest to highest density, are the Continental crust, Oceanic crust, Asthenosphere, Outer core, and Inner core.

The layers of the Earth can be ordered by density from lowest to highest as follows: Continental crust, Oceanic crust, Asthenosphere, Outer core, and Inner core.

The Continental crust being the top-most layer, has the lowest density, ranging between 2.2 to 2.9 g/cm³. Below that, the Oceanic crust has a slightly greater density at about 3.0 g/cm³.

Below these crust layers is the Asthenosphere, part of the upper mantle, with a density ranging between 3.2 and 3.3 g/cm³.

The denser Outer core lies beneath with a density ranging from 9.9 to 12.2 g/cm³. At the core of the Earth, the inner core has the highest density, ranging from 12.6 to 13.0 g/cm³.
