A. There is no movement
Hope this helps
Answer:
Random samples
Explanation:
It needs to be random so that there isn't bias that would skew the consistency
Answer:
3H₂SO₄ + 2Al₂(SO₄)₃ → Al₂(SO₄)₃ + 3H₂
Explanation:
3H₂SO₄ + 2Al₂(SO₄)₃ → Al₂(SO₄)₃ + 3H₂
In this type of reaction, one substance is replacing another:
A + BC → AC + B
In a single displacement reaction, atoms replace one another based on the activity series. Elements that are higher in the activity series. Also, if the element that is to replace the other in a compound is more reactive the reaction will occur. If it is less reactive, there will be no reation.
In the first equation, fluorine is more reactive than bromine. Therefore, bromine cannot replace bromine.
In the second equation, the displacement is between hydrogen and aluminium. Hydrogen is lower in the activity series, this implies that aluminum will replace it.
Answer: #1 The poppy seeds represent the protons, electrons and neutrons
#2 The fiberfill represents the nucleus #3 Protons and neutrons are in the nucleus #4 Electrons are the particles that are surrounding the nucleus #5 Because they are representing different things and they are their own entity
