Answer. 12 km/hr and 2 m are scalar quantities.

Explanation

Scalar quantities are those quantities which only have magnitude but no direction, for example: speed, time, mass etc.

Vector quantities are the quantities which have both magnitude and direction,for example : acceleration, momentum etc.

5 m northeast and 2 m north are vector quantities telling us magnitude and direction both that is 5 m in north east direction and 2 m in north direction.  

12 km/hr and 2 m are scalar quantities telling us only speed and distance respectively without specific directions.

10. Which best explains why the total mass of the product(s) would be less than the total weight of the
Olegator [25]

Answer:

D. Gases were released to the atmosphere

Explanation:

In accordance to the law of conservation of mass, the total amount of reactants must equate the total amount of products at the end of the reaction because matter can not be lost or created. However, certain changes like gas evolution, formation of precipitate etc. indicates the occurrence of a chemical reaction.

In a chemical reaction, the total mass of the product(s) would be less than the total weight of the reactant(s) because GASES, which constituted part of the mass of the reaction, WERE RELEASED INTO THE ATMOSPHERE. However, if the mass of the gas released can be accounted for, the amount of reactants and products must balance.
