The option that correctly compares a pure substance to a mixture is: B. A pure substance can only be separated by chemical means, whereas some mixtures can be separated by physical means.
A pure substance can be defined as a substance that has a definite and constant (fixed) structure and they are typically made up of only a kind of particles. Thus, a pure substance is a chemical substance that has a constant (fixed) chemical composition and properties.
As a result of a pure substance being a chemical substance, it cannot be separated into its constituents by a physical separation technique or method.
Instead, a pure substance being a chemical substance can only be separated by chemical separation technique or method.
In contrast, mixtures can be separated by a physical separation technique or method.

Hello,
The answer is A. Parallel circuit.
Unlike a series circuit, these circuits allow currents to flow through multiple branches. An open circuit is an electrical current that is not valid, therefore there will be no current flow. A combination circuit, I believe, <span>is a </span>circuit<span> that is a blend of series paths and parallel paths.

It is also likely (but not certain) that the photons will be absorbed by atoms. ... Light particles( or photons) never”run out” or loose their energy, so they can go an infinite distance, or until it reaches an object, that reflects the light or obsorbs it. Ie, a planet, or a mirror.
Answer:
The process of separation or deposition of crystals from a hot saturated solution on gentle cooling of the solution is called 'crystallisation'.
