The correct answer is:
TRIGONAL PYRAMIDAL
Answer:
electrical power. nnnnnnn
Answer:
C) low activation energy of forward reaction
Explanation:
Activation energy for the forward reaction is the quantity of free energy which is needed for a reaction to move from the reactant phase of energy level to the transition state of energy level. The higher the rate of energy level, the slower the chemical reaction.
Activation energy is a barrier that must be overcome for a reaction to take place.
Explanation:
CaCl2 ⇄ Ca-²+2Cl-¹
1mole⇄1mole+2moles
So from above ..
1mole CaCl2 produce 1mole Ca-² & 2 moles of Cl-².
For 2.5 moles we multiply the above chemical eq. With 2.5
2.5CaCl2⇄2.5Ca-²+5Cl-¹
So from 2.5 moles of CaCl2 we get 2.5 mole calcium ion and 5 moles chloride ion…
The percent yield of reaction = 65.27%

Reaction
2Pb(s)+O₂(g)⟶2PbO(s)
mass of Lead(Pb) = 451.4 g
mol of Pb (MW=207 g/mol) :
mol of lead(II) oxide (PbO) based on mol Pb as a limiting reactant(Oxygen as an excess reactant) :
mass of PbO(MW=223 g/mol)⇒theoretical :
The percent yield :
theoretical = 486.14 g
actual = 317.3 g
