C.  Cu undergoes reduction.

Anna11 [10]4 years ago
4 0

Answer: C.) Cu undergoes reduction.

Explanation:

Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)

I)  Oxidation reaction : involves loss of electrons and there is an increase in oxidation state number.

Fe\rightarrow Fe^{2+}+2e^-

Fe metal has undergone oxidation, as its oxidation state is changing from 0 to +2 in FeSO_4.

ii) Reduction reaction : involves gain of electrons and there is a decrease in oxidation state number.

Cu^{2+}+2e^-\rightarrow Cu

Copper(II) ion has undergone reduction, as its oxidation state is changing from 2+ to 0. Copper ions are getting converted into copper metal.

Explain what environmental bias means. What are the categories that
rewona [7]

Answer: Environmental bias can be defined as the idea that suggests a group of people being living in the environment which is harmful for them.

Explanation:

There are three categories that make up the environmental bias there are socio-cultural choice, occupational choice, and personal choice.

The environmental bias can be related to chemistry as chemical lab is an area prone to chemical (acid, alkali) and fire so produced in reactions thus prone to accidental hazards not safe for working of people. But people like to work in chemical lab due to their personal and occupational choice.

Identify which one is the reducing agent in this reaction
Romashka-Z-Leto [24]

Answer:

Na.

Explanation:

  • The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
  • An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.
  • A reducing agent (also called a reductant or reducer) is an element (such as calcium) or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.

  • For the reaction:

<em>2Na + S → Na₂S.</em>

<em></em>

Na is oxidized to Na⁺ in (Na₂S) (loses 1 electron). "reducing agent".

S is reduced to S²⁻ in (Na₂S) (gains 2 electrons). "oxidizing agent".

Which of the following best describes a metal? Brittle, shiny, and solid Brittle, dull, and low density Malleable, shiny, and ab
yanalaym [24]

Answer : The correct option is, Malleable, shiny, and able to conduct heat or electricity.

Explanation:

Metals : Metals are the elements which can easily loose electrons and forms cations.

Properties of metals :

  • They are lustrous (shine).
  • They are malleable and ductile (flexible).
  • They conduct heat and electricity.
  • The metallic oxides are basic in nature.
  • They form cations in an aqueous solution.

Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.

Properties of non-metals :

  • They are non-lustrous.
  • They are brittle and hard in nature.
  • They do not conduct heat and electricity.
  • The non-metallic oxides are acidic in nature.
  • They form anions in an aqueous solution.

Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.
