Explain why the noble gases tend not to react
harkovskaia [24]
The noble gases don't react because they have their full orbital. They have 8 valence electrons, meaning that they are happy and stable. They dont need any more electrons, which means that they dont need to bond. That makes them un- reactive.

A group of students removed the plastic insulation around a wire. They wrapped the uninsulated wire around a steel rivet 50 time
maksim [4K]

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

two kilogram of nasialo4 zeolites are used in a water filter to remove calcium. after complete ion exchange the zeolite is remov
defon

After ion exchange with zeolite in water filter to remove calcium by substitute natrium ion with calcium ion, the weight of zeolite become 1.9578 kg.

ion exchange calculation can be done by using basic stoichiometry if we know how the reaction of the ion exchange. In this case where zeolite with natrium ion will be exchanged with calcium. The reaction of exchange will be like this:

2NaSiAlO_{4} + Ca^{2+} ⇒ Ca(SiAlO_{4}) _{2} + 2Na^{+}

Calculate the molecule weight of both zeolite
Atomic weight data:
Na = 23 gram/mole

Si = 28 gram/mole

Al = 27 gram/mole

O = 16 gram/mole

Ca = 40 gram/mole

Molecule weight

NaSiAlO_{4} = 142 gram/mole

Ca(SiAlO_{4}) _{2} = 278 gram/mole

Calculate mole from 2kg of zeolite with natrium :

2000 gram/ 142 = 14.0845 mole

Based on the stoichiometry, we got the mole of zeolite with calcium:

14.0845 mole x 1/2 = 7.0423 mole

Weight of zeolite after the ion exchanged with calcium:

7.0423 mole x 278 = 1957.8 gram = 1.9578 kg
