I think the correct answer is false. Protons are not the ones responsible for an element’s chemical behavior rather it is the electrons. This is because it is the electrons that are responsible for bonding. It is what dictates certain properties like boiling point and melting point
Answer:
Hi, there your answer is A. As the frequency of a wave increases, the shorter its wavelength is.
Explanation:
When frequency increases, wavelength decreases.
Hope this Helps :)

The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic. It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.
Answer:
Hydrogen and chlorine need to be balanced. There is an equal amount of magnesium on each side.
Explanation:
The given chemical equation does not hold the law of conservation of mass because the number of atoms of hydrogen and chlorine are not balanced on each side.
Chemical equation:
Mg + HCl → MgCl₂ + H₂
Balanced chemical equation:
Mg + 2HCl → MgCl₂ + H₂
Now this equation hold the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
