A reaction that involves reagent X as the limiting reagent is begun with an initial concentration of 0.732-M X. The reaction rea
katovenus [111]

Answer:

The answer to the question is 0.0122 m/s

Explanation:

The rate of a reaction is the measure of the change in concentration of a reagent within a specific time frame. Reaction rate of a substance can be calculated by finding the division of the concentration change of the substance and the time required to undergo the change in concentration.

Average reaction rate \frac{Change in the moles count of X}{Change in time} =

The initial number of moles of X = 0.732 moles and final number of moles of X  = 0 moles and the time it took to effect the change = 60s

then the rate of reaction = \frac{0.732}{60} = 0. 0122 moles per second

the rate of the reaction involving X = 0.0122 m/s

Which describes the role of oxygen in photosynthesis?
Basile [38]
Photosynthesis is the process utilized in the chloroplasts of plant cells, where carbon dioxide and water undergo a chemical process with radiant energy, usually from the sun. The resulting products are energy stored in the form of a glucose molecule, and oxygen, which is given off as a waste product.

slega [8]

Answer:

CaF2

Explanation:

Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from hydronium, which is transformed into a water. Picture is attached.
