Answer: The author used the word "conversely" because the first statement he made is in CONTRAST to the second statement he made.
Explanation:
Matter is made up of atoms or molecules that are in constant motion. The motion of these tiny particles ( molecules) gives the object energy. The movement of these molecules depends on the state of matter which includes
--> GASEOUS STATE: Here, the particles are completely free to move and are always in motion.
--> LIQUID STATE: particles in this state slide by one another and are always in motion.
--> SOLID STATE: particles in this state are held tightly together but are always in motion.
Also, the molecules in motion are greatly affected by temperature changes. Increase in temperature will cause the particles in the liquid to move faster. Such is seen when soup is heated, the molecules travel faster than before. But the OPPOSITE is seen in an ice cube. This is because the ice cube is in solid state and of a lower temperature.
It’s is 130 that is the answer!!!!
A) Anode - hydrogen gas
Cathode-oxygen gas
B) Hydrogen gas - The gas burns with a pop sound
Oxygen gas - The gas rekindles a glowing splint
C) The volume of gas produced at the cathode is 23
<h3>What is electrolysis?</h3>
Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The electrolysis of water produces two volumes of hydrogen at the anode and one volume of oxygen at the cathode.
The hydrogen gas burns with a pop sound. It is easily identified by this test. Also, oxygen is known to rekindle a glowing splint and this is a commonly used test for oxygen gas.
Since the ratio of hydrogen produced at the anode to oxygen produced at the cathode is 2:1 by volume; then when 23 of oxygen is produced at the cathode, 46 of hydrogen is produced at the anode.

Answer : The correct option is, (D)
Explanation :
Balanced reaction : Balanced reactions are those reactions when the number of different atoms of the element present in the reactant sides is equal to the product sides.
The given unbalanced reaction is,
The balanced chemical reaction is,
Therefore, 1, 1, 2, 1 are the coefficients that would correctly balance this equation.
