a) upon heating, a blue powder turned white and lost mass b) A white soil forms three different gasses when heated. The total mass of the gases is the same as that the solid.
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.
For each of the changes, decide whether two or more elements formed a compound or If a compound decomposed (to elements or other compounds). Explain your reasoning in each case.
- a) upon heating, a blue powder turned white and lost mass
- b) A white soil forms three different gasses when heated. The total mass of the gases is the same as that the solid.
