Answer : The correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
Explanation :
Electrochemical cell : It is a type of device which is used to convert the chemical energy into electrical energy during the redox reaction.
In the electrochemical cell, there are two electrodes. The electrode on which the oxidation takes place is called the anode (or negative pole) and the electrode on which the reduction takes place is called the cathode (or positive pole). This cell is connected by the salt bridge.
In the external circuit, the electrons flow from the anode (negative pole) to cathode (positive pole) through the voltmeter.
In the inner circuit, the ions flow through the salt bridge.
Hence, the correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
Real quick, I will tell you why i think it does from a scientific point of veiw, but I dont know for sure.
The reason that the Earth goes through so much change on a regular basis is because of Gravity. What Gravity is doing is pulling objects to the Earth that it can reach (Which you probably knew) and so when it does this, it is pulling at the earths surface as well, causing constant change.
I hope this helps you!
Given :
Compared with a mole of oxygen-16, a mole of sulfur-32 contains:
A. twice as many atoms .
B. half as many atoms .
C. an equal number of atoms .
D. 8 times as many atoms .
To Find :
The correct option .
Solution :
One mole of atoms of oxygen-16 has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 
atoms of oxygen.
Same, one mole of sulfur-32 has 32 g mass , and contains same atoms of sulfur .
So , both have equal number of atoms .
Therefore , option C. is correct .
Hence , this is the required solution .
The human body<span> contains </span>many<span> salts, of which </span>sodium<span> chloride NaCl is the major one, making up around 0.4 per cent of the </span>body's<span> weight. So a 50kg</span>person<span> would contain around 200g of </span>sodium<span> chloride - around 40 teaspoons. Since we lose </span>salt<span> whenever we sweat, it has to be continually replaced. Answer: C.</span>
<span>D) Temperature is lower so the air inside the tires contracts
In cold, we all know temperature is lower, and we know, it reduces the movement of air, so it contracts
