1. in a chemical equation, the mass of the reactants was 15 g, the mass of the
products was 12 g, did this chemical reaction follow the law of conservation
of massa
a. yes
b. no
c. you can't tell with the given information
so what is the answer

b. No

Explanation:

The law for the conservation of pasta was drafted in 1774 by the French chemist Antoine Laurent Lavoisier. The experimental studies carried out by Lavoisier led him to conclude that in a chemical reaction, which takes place in a closed system, the sum of the masses of the reagents is equal to the sum of the masses of the products. For this reason, we can say that the question above does not show a chemical reaction that obeys this law, since the masses of reagents and products are not the same.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

the first part is ocean
