During a lab experiment, two learners carried out a chemical reaction in a tightly sealed container, combining 10 grams of compound A with 15 grams of compound B. After the reaction, they noticed the formation of a new compound C and a residue D. Given that the total mass of the products was 25 grams, which weight law can the learners refer to in order to explain there was no loss of mass during the reaction, and how does this law relate to the context of the described experiment?a.
The weight law pertinent to the described experiment is Proust's Law, which states that the mass composition of a pure compound remains constant.
b.
The weight law that applies to the described experiment is the Law of Conservation of Mass, also known as Lavoisier's Law.
c.
The weight law that applies to the described experiment is Dalton's Law, which focuses on the combination of elements in specific proportions to form compounds.
d.
The weight law relevant to the described experiment is the Law of Multiple Proportions, which explains how two elements can combine in varied ratios to create different compounds.
e.
The weight law applicable to the described experiment is the Law of Definite Proportions, which asserts that a chemical compound is always made up of the same elements in fixed mass ratios.

During a practical in the Chemistry lab, the learners mixed various elements and observed the properties of the compounds that formed. They observed that the compound resulting from the reaction of sodium and chlorine creates crystals that conduct electricity when dissolved in water, while the mixture of carbon and hydrogen results in a substance that doesn’t conduct electricity and has a lower melting point. Based on these observations, what type of chemical bond is present in NaCl and CH₄, respectively?
