Answer: The correct answer is option(A).

Explanation:

Litmus paper is used to test whether given solution is acidic or basic(alkaline).

There are two types of litmus paper:

1) Blue Litmus paper: The color of this litmus paper is blue, when treated with acid it turns red and when treated with base it remains blue.

2) Red Litmus paper:The color of this litmus paper is red, when treated with acid it remains red and when treated with base it turns blue.

Since, the substance in beaker did not change the color of blue litmus paper which means that it is a base.

When water is electrolyzed, it splits into hydrogen and oxygen.
Westkost [7]

The mass of water is equal to the combined mass of hydrogen and oxygen.

<h3>What is Mass?</h3>

This is defined as the quantity of matter in a physical body. The electrolysis reaction of water can be seen below:

2 H₂O ---> 2 H₂ + O₂

We can deduce that 36 grams of H₂O dissociated to give 4 grams of H₂ and 32 grams of O₂ which option D was chosen as the appropriate choice.

velikii [3]
If you increase the frequency, the photon will have more energy and can therefore transfer more electrons to the other side. As such, you will have an increased current.
