Answer:
See attachment.
Explanation:
Elements that are in the same group will definitely possess similar characteristics because they tend to have the same valence electron which determines their reactivity.
On a periodic table, elements in the same group can be found arranged on the same column in the periodic table.
Therefore the two elements that have similar characteristics are those two elements you can see on the same column in group 2. See the two elements indicated in the attachment below.
Explanation:
Molecular formula for Propene = C3H6
The isomer of propene is cyclopropane.
(Draw a triangle to show that it is cyclopropane)
Answer:
I think it is called demagnetisation.
Answer:
CO₂
Explanation:
The product of the reaction is CO₂.
In a chemical reaction, the product is the substance usually found on the right hand side of the expression.
Reaction equation is given as;
C + O₂ → CO₂
In this reaction, C and O₂ are the reactants
CO₂ is the product of the reaction.
- This reaction is called a combination reaction in which two species combines to give a product.
Answer:
That would be helium, with a melting point of 0.95 K (-272.20 °C)—although this happens only under considerable pressure (~25 atmospheres). At ordinary pressure, helium would remain liquid even if it could be chilled to absolute zero.
