The correct answer is A. Can I get the Brainliest?
Answer:
The cathode is the electrode where the reduction takes place.
Explanation:
Cell has three components:
an electrolyte and two electrodes which is a cathode and an anode.
Electrolyte is usually solution of the water or other solvents in which the ions are dissolved.
<u>In electrolytic cell:</u>
Negatively charged electrode is the cathode where the process of reduction takes place.
Positively charged electrode is the anode where the process of oxidation takes place.
<u>In galvanic cell:</u>
Positively charged electrode is the cathode where the process of reduction takes place.
Negatively charged electrode is the anode where the process of oxidation takes place.
<u>So, the correct answer is - The cathode is the electrode where the reduction takes place.</u>
Power is defined in a mathematical expression as P = F x v where F is in N and v is in m/s. From the given equation, the v = d/t which is v = 10/ 6, then substituting the answer to the power formula W = 54 N (10/6 m/s) = 90 Watts.
The symbol of the period five element that is a member of the pnicitides family are antimony.
Explanation:
Pnictogen family
- In periodic table, column 15 elements are Pnitogen family.
- The pnictogen elements are Nitrogen-N, arsenic-As, phosphorus-P, bismuth-Bi, antimony-Sb, ununpentium-Uup.
- There are five valence electrons each member of pnictogen family. In group 15 double bonds and triple bonds are formed due to these valence electrons.
- Pnictides, binary compounds of group 15.
Antimony
- Antimony is the element found in period 5 and block p.
- A chemical element, Antimony (Sb) from Latin word stibium and 51 is its atomic number. It is in solid state.
- In ancient times, antimony compounds are used as cosmetic and medicine.
- Appeared as semi metal.
- Electronic configurations of Sb is [Kr] 4d105s25p3.
