Suppose a student starts with 2.4464 g of a sand mixture and separates the components into 1.3012 g of NaClNaCl , 0.5553 g of SiO2SiOX2 , and 0.4503 g of CaCO3CaCOX3 . Based on the amount of recovered, what is the percent of SiO2SiOX2 in the starting mixture?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Suppose a student starts with 2.4464 g of a sand mixture and separates the components into 1.3012 g of
, 0.5553 g of
, and 0.4503 g of
.
Based on the amount of recovered, what is the percent of
in the starting mixture?
According to the question, we had a sand mixture consisting of NaClNaCl, CaCO3CaCOX3, and SiO2SiOX2.
Mass of sand mixture = 2.4464 g
Mass of NaClNaCl = 1.3012 g
Mass of SiO2SiOX2 = 0.5553 g
Mass of CaCO3CaCOX3 = 0.4503 g.
