Answer:
The economics in costing is explained below in complete details.
Explanation:
The economic cost is the blend and mixture of wastes of any assets that have a worth connected to them by any one person. The economic cost is practiced largely by economists as a method to examine the prudence of one sequence of performance with that of another. The economic cost varies from accounting cost because it incorporates opportunity cost.
Answer:
Kernels are placed in a pan on a stove
Explanation:
Heat transfer by conduction involves the actual movement between particles of the medium. For conduction to occur, the particles must be in contact with the heating medium or the body at a higher temperatures.
For the popcorn kernels to conduct heat using the conduction heat transfer process, the kernels are placed in contact with the heat source using the frying pan. The stove is the heat source.
When put a knife in contact with fire, it is heat transfer by conduction.
Answer:
a) Ag(NH₃)₂⁺, Cl⁻.
b) NH₃.
c) AgCl.
Explanation:
Based on LeChatelier's law, a system in chemistry can change responding to a disturbance of concentration, temperature, etc. in order to restore a new state.
In the reaction:
AgCl(s) + 2NH₃(aq) ⇌ Ag(NH₃)₂⁺(aq) + Cl⁻(aq)
When reactants are added, the system will produce more products restoring the equilibrium and vice versa. A reactant in solid state doesn't take part in the equilibrium, thus:
a) Ag(NH₃)₂⁺, Cl⁻. The addition of products will shift the equilibrium to the left
b) NH₃. The addition of reactant will shift the equilibrium to the right.
c) As AgCl is in solid phase, will not shift the equilibrium in either direction.
Ag+CuSO4
Silver is lower than copper in the electrochemical series and therefore would not displace it in any reaction.
