Suppose of hcl and of o2 are added to an empty flask. how much will be in the flask at equilibrium? a. none. b. some, but less than 155. mmol, c. 155. mmol, d. more than 155. mmol

This is an incomplete question, here is a complete question.

Hydrogen chloride and oxygen react to form water and chlorine, like this:

Use this chemical equation to answer the questions in the table below.

Suppose 155. mmol of HCl and 38.8 mmol of O₂ are added to an empty flask. How much HCl will be in the flask at equilibrium?

(1) None.

(2) Some, but less than 155. mmol,

(3) 155. mmol,

(4) More than 155. mmol,

Answer : The correct option is, (1) None

Explanation :

The given balanced chemical reaction is:

From the balanced chemical reaction, we conclude that

As, 4 mmole of HCl react with 1 mmoles of

So, 155. mmole of HCl react with mmoles of

That means, is excess reagent and is a limiting reagent. All the moles of HCl will consume.

Hence, the correct option is, None.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
