Answer:
C. An external voltage source
Explanation:
An electrolytic cell converts electrical energy from an external voltage source into chemical energy that drives a reaction.
The external voltage source is usually a battery. This energy form generated from the battery helps to drive chemical reactions.
The process involves the decomposition of an ionic compound by means of current passed into the aqueous or molten form of the compound through conductors known as electrodes.
delta g must be negative in order for the reaction to be spontaneous bb ♡
Answer:
uses of photosynthesies:
Explanation:
In photosynthesis ENERGY from light is used to convert CARBONDIOXDE and water into glucose and oxygen for 6 carbon and 6 water molecules, 1 glucosed and 6 oxygen molecules are produced.
It can be a compound or a single element. An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. There are about 117 elements, but carbon, hydrogen, nitrogen and oxygen are only a few that make up the largest portion of Earth.
I would say pure substances
In a nuclear fission reaction, a freely moving neutron is introduced to a nuclear fuel, then a neutron is absorbed by an atom's nucleus.
<h3>What is nuclear fission?</h3>
Nuclear fission is a process in which an unstable nuclei will convert into stable nuclei after releasing the energy in the form of particles.
When we introduce a freely moving neutron to the nuclear fuel of uranium-235 nuclei then this introduced neutron was absorbed by the nuclei and makes the nuclei more unstable. Then this unstable nuclei will convert into two nuclei in the addition of three neutrons.
Hence, a neutron is absorbed by an atom's nucleus.
