Answer:
There is the same amount of matter before and after the reaction
The atoms are arranged in different compounds and molecules.
There are the same types and number of atoms before and after the reaction
Explanation:
--The same amount of matter before and after the reaction and the same types and number of atoms before and after the reaction is because of the law of conservation of mass. Matter cannot be created or destroyed.
--the reacting atoms and molecules will undergo a transformation to different molecules and compounds. Can be predicted because of the types of chemical reactions:
combination (combining 2 elements to create a new compound)
Decomposition (a compound breaking down into different parts)
Single and Double displacement (the molecules/ atoms will change who they are paired with)
Answer:
False
Explanation:
Gasses and have more space between molecules
What context are you asking it in?
The answer could be the electromagnetic interaction if you're talking about the 4 fundamental interactions, or ionic interaction, or electrostatic interaction.
1 mole -------- 22,4 L ( at STP )
0.030 moles --- ?
V = 0.030 * 22,4 / 1
V = 0.672 L
hope this helps!
