Number of moles = number of atoms/Avogadro's number
= (4.8x10^25)/(6.02x10^23)
=79.7 mol (3sf)
Answer:
Terms in this set (31) A reaction that involves the transfer of electrons from one molecule to another is referred to as. a redox reaction. During an oxidation reaction, the donor molecule loses an electron and becomes oxidized.

Answer:
When silver metal is reacted with the solution of lead nitrate at that time silver nitrate is formed along with lead metal.
Explanation:
The balanced equation of the given reactio is
Pb(NO3)2 + 2Ag= 2AgNO3+ Pb
In this reaction lead nitrate Pb(NO3)2 reacts with silver(Ag) to form a salt Silver nitrate(AgNO3) along with lead metal(Pb).
Based on what you have read about wind turbines and dams, how does a generator work? A loop of ______ spins in a ______ field, producing ______ current.
Answer:
Wire
Magnetic
Electric
Explanation:
The generator works on the principle of converting mechanical energy into electrical energy.
For example in a wind turbine generator, the mechanical energy is the wind that pushes the blades of the turbine directly that leads to conversion of this it's linear motion to the rotary motion required to make rotor of the generator to spin. Finally, the harder the wind pushes, the more the mechanical energy applied and consequently, the more electrical energy can be generated.
Now, all generators work because of the effect of the magnetic field moving past an electrical coil.
Thus, the movement of a magnet across a single loop of wire produces a voltage that is induced within the wire loop as a result of the magnetic field produced by the magnet.
As a voltage is induced across the wire loop, electrons begin to flow around the loop thereby generating electric current.
Answer:
Explanation:
Branches or side chains are called alkyl radicals, they are named substituting the termination -ano for -yl or -il when it is part of a hydrocarbon.
