I would say you are correct so b 4.6
CUSO4 is an example of A COMPOUND.
A compound is the product formed when two or more elements chemically combine together to form a new product or products, which are quite different from the reactants. The elements in the compound are usually combined together in a specific ratio. In the question given above, CUSO4 is a compound because, copper, sulphur and oxgyen had combined together chemically to form a new compound, which is CUSO4. The ratio of combination is 1:1:4, that is, one atom of copper combine with one atom of sulphur and four atoms of oxygen to form one molecule of CUSO4.
The answer my friend is dense and here is why if you compact dense food it becomes even more flat and there is more room for food.
The periodic table was arranged by Mendeleev in the increasing order of atomic numbers. The arrangement sees to it that the elements belonging to the same column has similar properties and the rows are arranged in increasing number of valence electrons. The answer here is true.
Answer:
Iron w/Zinc. Metals react in weather of any type…and it is chemists job to try to figure out how to slow that process down. Zinc is a metal that is often coated on top of steel which is called galvanizing the steel, or “Galvanized Steel.” This process will help to slow down the rust as the zinc acts as an additional barrier to the air and moisture getting to the steel/iron.
