The correct answer is -

FALSIFIABLE:

Aloe vera gel can heal wounds by boosting cell renewal.

Drinking aloe juice can reduce the risk of lung cancer.

NON-FALSIFIABLE:

Aloe vera gel is the best natural skin moisturizer.

Aloe vera juice tastes better than carrot juice.

Explanation:

Falsifiable is the ability or chances of any hypothesis, claim or statement to be proved wrong. In such a hypothesis, it is possible to carry an experimental observation that disproves the idea in claim or question.

In the given examples

Aloe vera gel can heal wounds by boosting cell renewal.

Drinking aloe juice can reduce the risk of lung cancer.

There is no observation in the favor of the claim so there more likely to be falsifiable whereas, Aloe vera gel is the best natural skin moisturizer.

Aloe vera juice tastes better than carrot juice are more non-falsifiable as these are based on personal choice or experimental observation.

C2H4O2 + NaC2H3O2 + H2O + CO2 list the reactants in this chemical reaction
lisabon 2012 [21]

Answer:

C₂H₄O₂ and NaC₂H₃O₂ are reactants.

Explanation:

Word equation:

Acetic acid + sodium acetate  → sodium diacetate

Chemical equation:

C₂H₄O₂ + NaC₂H₃O₂  →  C₄H₇NaO₄

This is a synthesis reaction in which simple reactants combine to form complex product.

This is also balanced chemical equation because there are equal number of atoms of all elements on both side of equation. Thus it follow 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.

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.
