Answers cannot complete your homework for you, sorry.
But you can follow the link, below, to learn more about pure substances vs mixtures.
The five characteristics of a mineral are: naturally occurring, inorganic, solid, definite chemical composition, and orderly internal structure/crystalline structure. Coal is organic in origin, derived from plant material, making it not inorganic as required by the mineral definition. A glass marble is manufactured by humans and lacks a naturally occurring origin, so it does not meet the criteria of being naturally occurring.

The mass listed on the periodic table for an element is a weighted average of the masses of its naturally occurring isotopes, taking into account their relative abundance. In the case of bromine, its mass is 79.9 amu because it includes the isotopes with masses slightly below and slightly above 80 amu. It is possible for an element’s average mass to not match any individual isotope due to the varying abundances of its isotopes.
A mixture is a physical combination of two or more substances that are not chemically bonded, allowing their composition to vary. This is because mixtures retain the properties of their individual components and can be easily separated through physical means, while compounds are chemically bonded in fixed ratios, resulting in consistent composition and properties.
Leaves are considered organic matter because they are made up of living or once-living organisms that contain carbon. They are composed of organic compounds such as cellulose, lignin, and chlorophyll, which are essential for the growth and function of plants. When leaves decompose, they break down into organic materials that enrich the soil and provide nutrients for new plant growth, completing the organic matter cycle.
Chemistry explain the chemical composition and structure of materials, the interaction of substances and produce new materials.

A law is a description of a naturally occurring phenomenon, whereas a theory attempts to explain a law.
raw material - gold, bauxite, diamond natural resource - trees, water, animals basically raw materials are ores found in their state i.e bauxite is found in the ground and aluminum is extracted from it natural resource are naturally occurring and don't need altering, generally have uses to human beings

Coal is not a mineral because it does not have a crystalline structure, which is a key characteristic of minerals. Instead, coal is a naturally occurring organic sedimentary rock made up of the remains of plants and animals that have undergone compaction and chemical changes over millions of years.
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
no
To be a mineral, a substance must be naturally occurring, inorganic, solid, have a definite chemical composition, and have an ordered atomic structure. Coal is organic in origin, formed from the remains of plants; therefore, it is not a mineral. A glass marble is man-made and lacks a naturally occurring origin, so it also does not meet the criteria to be considered a mineral.
it has dissolved substances in it
There is ample evidence that ebola is a naturally-occurring virus. There are many animals with antibodies to ebola and similar viruses. It is human nature to look for a conspiracy to explain such a natural force, but there is no science behind the belief that ebola is man-made.
