rainstorming space: (what you need to know/figure out in order to give a good hypothesis). Procedure: (please write a list of steps that you will follow to figure out the answer). Conclusion: I measured _________g of Al( ) . Therefore, I used ___________ mol of Al t. That also means I used ________________________ particles of Al.
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.
Atoms in Aluminum Foil
Problem: How many atoms of Aluminum (Al) are in a piece of aluminum foil?
Hypothesis: I predict there will be_________ atoms of aluminum in a ___cm" x ____cm" piece of aluminum foil :
Brainstorming space: (what you need to know/figure out in order to give a good hypothesis).
Procedure: (please write a list of steps that you will follow to figure out the answer).
Conclusion:
I measured _________g of Al( ) . Therefore, I used ___________ mol of Al t. That also means I used ________________________ particles of Al.
Suppose:-
Thickness of aluminium foil is = 1cm
Width of aluminium foil = 2cm
Length of aluminium foil = 2cm
Volume of aluminium foil = Length× Width × Volume
Volume = 2 × 2 × 1
= 4cm3
