Which of the following statements about balanced chemical equations is true?

Chemistry

Answer:

The answer is all three

Explanation:

Balanced chemical equations demonstrate that the total number of atoms of each element are conserved during a chemical reaction. These equations are useful because they provide the molar ratios of the reactants and products in a chemical reaction, and they allow the theoretical masses of reactants and products to be calculated.

Answer:

The correct answer is They provide the molar ratio of reactant and products in a chemical reaction.

Explanation:

Balanced chemical equation helps us to calculate the number of moles of both reactant and product.For example

    2H2+O2=2H2O

From the above balanced equation it can be stated that 2 molecules of hydrogen(H2) reacts with 1 molecule of oxygen(O2) to form 2  molecules of water.

Los hermanos Ana Victoria y José Leonardo están patinando en el hielo, con 25 y 20 kg respectivamente de masa, si Victoria empuj
andreyandreev [35.5K]

Utiliando las leyes de Newton encontraremos que la aceleración de Ana es -1.6 m/s^2.

La segunda ley de Newton dice que:

F = m*a

Fuerza es igual a masa por aceleración.

La tercera ley de Newton dice que cuando dos objetos interactuan, cadan objeto ejerce una fuerza de <u>igual magnitud pero opuesta direccion</u> en el otro.

Ahora veamos como aplicar esto.

Sabemos que la niña empuja al niño, asumamos que con una fuerza F.

Tendremos entonces la ecuación:

F = 20kg*(2m/s^2) = 40N

Y por la tercer ley de Newton, esta misma fuerza (pero en opuesta dirección) se aplica a la niña, entonces tendremos:

-40N = 25kg*a

-40N/25kg = a = -1.6 m/s²

La aceleración con la que retrosede la niña es -1.6 m/s²
