In a chemical change what is always formed?
A chemical change always forms one or more products which can be elements, molecules, and/or compounds.
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
What is always true of a binary compound?
A binary compound always contains two different elements. This means it will have a chemical formula consisting of two elements in fixed proportions. Binary compounds typically involve a metal and a nonmetal.
What is shales chemical symbol?
It doesn't have one. Shale is a mixture and doesn't always have the same composition. Only elements have chemical symbols
What is always true of binary compounds?
A binary compound is formed from two different chemical elements.
What always has the same chemical formula?
Elements have the same chemical formula because they are made up of only one type of atom. For example, the chemical formula for gold is always Au, regardless of its form.
Does the chemical makeup quartz ever change?
No chemical formulas ever change. If there are different elements in a compound, it ceases to remain the same compound, and becomes a new compound.The chemical formula for quartz is SiO2. That is, always was, and always will be the chemical formula for quartz.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
What always stays the same in a compound?
a compound always has the same chemical formula
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
What is the law of proportions?
A chemical compound always contains exactly the same proportion of elements by mass. ---------------------------------------------------------------------------------------------------- A law that states that a compound always contains the same elements in the same proportions. Source: e2020
What kind of substance always has properties that are hard to see?
For example very rare radioactive chemical elements.
