What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they accommodate 6 neutrons and 6 electrons but each contains a difference number of protons - 6, 7, and 8 respectively. B) These are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively. Eliminate C) These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively. D) These are allotropes of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
Answer:
These are isotopes of carbon they both contain 6protons and 6electrons but each contains a diff about of neutrons 6,7 and 8 respectively

B. Peptides is not a type of carbohydrate.
What are carbohydrates?Carbohydrates are organic compounds that are an important source of energy for the human body. They are composed of carbon, hydrogen, and oxygen, and can be simple or complex in structure.
Simple carbohydrates, also known as sugars, include monosaccharides such as glucose and fructose, and disaccharides such as sucrose and lactose. Complex carbohydrates, such as starches and fibers, are made up of long chains of simple sugars. Carbohydrates play a crucial role in providing energy for physical activity and maintaining healthy brain function. A balanced diet should include a variety of carbohydrates, with a focus on complex carbohydrates for sustained energy and good health.

A mineral forms from water at the edge of a lake. Which statement best describes this mineral? The mineral formed from lava. The mineral formed through evaporation. The mineral formed when hot water cooled. The mineral crystallized from magma.
Answer:
The mineral formed through evaporation.
Explanation:
Minerals are inorganic substances that occur naturally i.e. not man-made. These minerals are formed in different ways in nature. One of those ways is through EVAPORATION.
Since water dissolves a lot of substances including the particles of these minerals, the mineral components can be found in a dissolved state in water bodies e.g lakes, oceans etc. However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out.
This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
Answer:
The mineral formed through evaporation.
