Answer:
An ion.
Explanation:
Atoms can gain or lose electrons and become ions, which are atoms that have a positive or negative charge, because they have unequal numbers of protons and electrons.
Answer:
= 2/3
Explanation:
The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain
Y = 
let's use the subscript "o" for rod A
I = 
tells us that rod B has
A = 3 A₀
L = 2 L₀
we substitute
Y = 
Y = 
y = ⅔ 
substituting the value of Y₀
Y = ⅔ Y₀
= 2/3
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
expressing adverse or disapproving comments or judgments.
