which of the following statements are true about chemical equations?
□ reactants are written on the right side of the equation; products are written on the left side.
□ reactants are written on the left side of the equation; products are written on the right side.
□ reactants are the chemicals that react together.
□ products are the chemicals that are produced at the end of a reaction.

Explanation:

Para ecuaciones químicas, los reactantes (sustancias que reaccionan) se escriben en el lado izquierdo, y los productos (sustancias formadas) en el derecho. Además, reactantes son las sustancias que reaccionan juntas, y productos son los formados al final de la reacción. La primera opción tiene los lados invertidos, así que es falsa. Las otras tres (segunda, tercera, cuarta) son verdaderas por la definición y estructura de ecuaciones químicas.

Answer:

B. Reactants are written on the left side of the equation; products are written on the right side.
C. Reactants are the chemicals that react together.
D. Products are the chemicals that are produced at the end of a reaction.
