Answer:
10 moles
Explanation:
of moles = given mass /atomic mass = 280 g /28 g = 10 moles of Si atoms in 280g sample.
Atoms must gain or lose electrons in order to become ions if they are to form ionic bonds.
The molarity of the diluted solution : 1.1 M
<h3>Further explanation</h3>
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
Can be formulated :
M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = Molarity volume of the solution after dilution
M₁=5
V₁=0.75
V₂=3.5
The electron is a subatomic particle that has a negative charge and a negligible mass. The electron travels around out side the nucleus.
The subatomic particles that are inside the nucleus are protons and neutrons.
The answer to your question is electron.
Chemical properties are those properties that become evident when the material experiences some sort of change. Although there are numerous chemical properties, some most basic ones are <span>reactivity with other chemicals, toxicity, flammability, heat of combustion, oxidation states, chemical stability<span>, types of chemical bonds that will form and others. Unlike physical characteristics that don't change the chemical when altered, changing chemical properties will affect the chemical.</span></span>
