Question

URGENT- please do by 14th July if possible!!!

1. How do metals react with acids?

2. What are the similarities and differences in the way different metals react with water and acids?

3. Why are some metal is more reactive than others

4. Why is the reactivity of metals so important to us?

5. What the displacement reactions?

6. Why do you displacement reactions happen?

7. Why are they important to us?

8. How are displacement reactions explained as redox reactions?

Thank you!

Answer 1

Acids react with most metals to form hydrogen gas and salt. ... When an acid reacts with metal, salt and hydrogen gas are produced

Answer 2

1. Metals react with most acids as to form a salt and hydrogen gas 2.I’m not too sure I’ll find out for you though after 3.metal elements either have 1,2 or 3 electrons in their outer electron orbit meaning when they react they tend to lose electrons in order to form ionic compounds some metals give up their electrons more readily meaning that they are more reactive. 4.the reactivity of metals is important to us as learning it enables us to determine which cation will replace the other from its aqueous solution 5.displacement reactions is when a metal from the electrochemical is mixed with the ions of a metal lower in the electrochemical series. 6.Displacement reactions happen due to the difference in the reactivity of the metals. 7.I’ll find out for u again. 8.Displacement reactions are explained as redox reactions as one species is being oxidised so it is losing electrons while the other is being reduced so it is gaining electrons.
