Answer: 323.61 g of
will be produced
Explanation:
The given balanced chemical reaction is :

According to stoichiometry :
2 moles of
require 1 mole of 
Thus 3.00 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product.
As 2 moles of
give = 2 moles of 
Thus 3.00 moles of
give =
of 
Mass of 
Thus 323.61 g of
will be produced from the given moles of both reactants.
Answer:
d. add another d-cell to the circuit
Explanation:
To make the electromagnet pick something, the student should add another d-cell to the circuit.
Simply, the electromagnet set up is generating very weak magnetic fields.
- To produce an electromagnet, there must be an interaction between electric fields an conductor.
- As the wire turns around in the vicinity of the electric field, it induces magnetism.
- The number of turns of wire here is pretty considerable.
- But the electric field is very weak.
- Additional d-cell in the circuit will circumvent this problem
For a neutral solution,
[H+][OH-] = 1 x 10⁻¹⁴
