Lithium and Francium, they are both in the sane group therefore share similar characteristics
The correct option is D.
An endothermic reaction is a type of reaction that absorb energy from the environment, thus, the energy level of the product is always higher than that of the reactants. During endothermic phase change, the potential energy of the system always increases while the kinetic energy of the system remains constant. The potential energy of the reaction increases because energy is been added to the system from the external environment.
3)
It has more surface area to react with
Answer:Rate of reaction can be determined in terms of concentration of reactants consumed or concentration of product formed per unit time
Explanation: For the reaction below
A ===>B
The reactant is A while the product given is B.
Reaction rate = Δ[B]/Δt = -Δ[A]/Δt
The concentration of A will decrease with time while the concentration of B will increases with time.
The negative sign in -Δ[A]/Δt is to convert the expression to positive since the change will always be negative (decreases)
Answer:
basically i not love chemistry lol
but my brother do...
Atkins Pyshical chemistry is right choice if you want to go deep
