Answer:
8 molecules of C₂H₄Cl₂
Explanation:
Molecules of C₂H₄ = 15 molecule
Molecules of Cl₂ = 8 molecules
Molecules of C₂H₄Cl₂ =?
First of all we will write the balance chemical equation,
C₂H₄ + Cl₂ → C₂H₄Cl₂
we are given 8 molecules of Cl₂ and 15 molecules of C₂H₄, which means that 8 molecules of chlorine react with 8 molecules of C₂H₄ and will limit the reaction product. The seven molecules of C₂H₄ will remain unreactive. So , the chlorine will be the limiting reactant.
8 molecules of Cl₂ × 1 mole of C₂H₄Cl₂/ 1 mole of Cl₂
8 molecules of C₂H₄Cl₂
Answer:
Observation
-I smell onions
-My dog weighs 45 pounds
-It is 85 degrees outside today
Predictions
-My dog will bark at the vacuum cleaner
although he has never seen it before
-My mother is going to cook spaghetti for
supper next Tuesday
-It will be a long, hot summer
Explanation:
The correct answer will be C. Carbon and Oxygen because these both are non metals and non metals react colvalently (i.e share electrons) while when metals react with a non metals they react ionically (i.e lose and gain electrons)
cobalt has a larger atomic radius
