Answer:
<h3>not reaching to the poles</h3>
Explanation:
1mile/13min * 1min/60sec * 63360in/1mil = 63360in/780sec = 81.23 in/sec
Answer:
- <em>Alkali metals react with water to produce </em><u>hydroxide and hydrogen gas</u><u>.</u>
Explanation:
That is a chemical property of <em>alkali metals</em>: they are highly reactive and <em>react </em>vigorously <em>with water</em> to produce the correspondant hydroxide and hydrogen gas.
These are some of those reactions:
- 2Li (s) + 2H₂O (l) → 2LiOH (aq) + H₂(g) ↑
- 2Na (s) + 2H₂O (l) → 2NaOH (aq) + H₂(g) ↑
- 2K (s) + 2H₂O (l) → 2KOH (aq) + H₂(g) ↑
The alkali metals are the elements of group 1 of the periodic table: Li, Na, K, Rb, Cs, and Fr. They have one valence electron which may lose easily to form an ion with charge +1.
Answer :
Part 1 : Yes, this reaction will take place.
Part 2 : No, this reaction will not take place.
Explanation:
Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.
It is represented as,

In this reaction, A is more reactive element and B is less reactive element.
Reactivity series : It is used to determine the products of the single displacement reactions. As we know that in a single displacement reaction, the most reactive metal displaces the least reactive metal.
Part A :
This reaction will takes place because iron metal is more reactive metal than copper metal. So, iron metal can displaces copper metal from its solution.
The chemical reaction will be:

Part B :
This reaction will not takes place because copper metal is less reactive metal than iron metal. So, copper metal can displaces iron metal from its solution.
The chemical reaction will be:
