In the diagram, the black line represents the concentration of a reactant and the green line represents the concentration of a product.

which statement best describes the reaction rate?

a. the product maintains an constant concentration in the first half of the reaction.

b. at the end of the reaction, both product and reactants are of a constant concentration.

c. the reactants maintain an constant concentration in the first half of the reaction.

d. at the end of the reaction, both product and reactants are of an equal concentration.

i think its a. correct if i am wrong. i need this answered asap.

The correct answer is :

B. At the end of the reaction, both product and reactants are of a constant concentration.

Explanation:

As you can see from the graph,

The concentration of reactant continously decreases with time

And the concentration of product continously increases with time.

But as the time proceeds , at the end of the reaction the concentrations of both reactant and product remains constant.

so the correct answer is :

B. At the end of the reaction, both product and reactants are of a constant concentration.

B. At the end of the reaction, both product and reactants are of a CONSTANT concentration.

Explanation:

Hope this helps!!

the correct answer is boyle

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
