(Q).
Q: What is the apparatus used for carrying out an electrolysis reaction? Read this paragraph and choose the correct option from the provided answers: An electrolytic cell is the apparatus used for carrying out an electrolysis reaction. In an electrolytic cell, electric current is applied to provide a source of electrons for driving the reaction in a nonspontaneous direction. In a voltaic cell, the reaction goes in a direction that releases electrons spontaneously. In an electrolytic cell, the input of electrons from an external source forces the reaction to go in the opposite direction. Choices: - Golgi apparatus - catalyst - an aqueous cell - an electrolytic cell A:
(A).
an electrolytic cell

Ques:Q: Microwaves are converted into what kind of energy in a microwave oven? Read this paragraph and choose the correct option from the provided answers: Electromagnetic waves may also be absorbed by matter and converted to other forms of energy. Microwaves are a familiar example. When microwaves strike food in a microwave oven, they are absorbed and converted to thermal energy, which heats the food. Choices: - solar energy - mechanical energy - light energy - thermal energy A:

Ans:thermal energy
