Answer : The correct option is, (4) 6.0 mol
Explanation :
The given balanced chemical equation is,
In this reaction, lead undergoes reduction and chromium undergoes oxidation.
Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.
Half reactions of oxidation-reduction are :
Oxidation : 
Reduction : 
From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.
Hence, the correct option is, (4) 6.0 mole
Answer:
D, Mixture
Explanation:
Mixtures can be separated physically because that's just how the world works
Answer:
kinetic energy
Explanation:
When the object is released, the gravitational potential energy is gradually converted into kinetic energy as it picks up speed.
2.5X20=50g
50g should be the right answer
Mass=volumeXdenisty.
What is likely to occur if sulfur forms an ionic bond with another element is <u>sulfur will accept electrons</u>
<u><em> explanation</em></u>
- Ionic bond is formed when a metal react with a non metal.
- Metal loses ( donate) electrons to form cation ( a positively charged ion) , while non metal accept (gain) electrons to form anion ( a negatively charged ion ).
- Sulfur is a non metal therefore it accept electrons if it form an ionic bond with a metal. sulfur accept 2 electrons to form S2- ion
