Which of the following accurately shows the correct terms for the two sides of a chemical equation, correctly placed to the left or to the right where they belong, and also shows the correct symbol that is written between them? Choose a,b,c, or d.
** I believe the answer is A.
A. reactants ---> products
B. products = reactants
C. reactants = sum
D. sum ---> reactants
The vocabulary and symbols in this question are covered in any chemistry textbook with many examples. You should look them over.
2 molecules of hydrogen +1oxygenolcule=2molcule of water.
To determine the correct answer, we need to understand the terms used in a chemical equation. In a chemical equation, the reactants are the substances that undergo a chemical reaction, and the products are the substances formed as a result of the reaction.
Now, let's examine each option:
A. reactants ---> products: This option correctly shows the reactants on the left side of the arrow and the products on the right side, which is the correct placement. The arrow, represented as "--->," indicates the direction of the reaction.
B. products = reactants: This option reverses the placement of reactants and products. The equal sign (=) is not typically used in chemical equations.
C. reactants = sum: This option incorrectly suggests that "reactants" is equal to "sum," which is not a valid term in chemical equations.
D. sum ---> reactants: This option reverses the placement of reactants and products, similar to option B. Additionally, using the word "sum" is not accurate in the context of a chemical equation.
From the analysis above, we can conclude that option A, "reactants ---> products," is the correct answer as it correctly shows the terms for the two sides of a chemical equation and the symbol (--->) between them.
