You have a stock bottle of HCl (aq) which is 12.1M, You need 400 mL of 0.10M HCl. How much of the acid and how much water will you need?

Answers

Mols of acid needed: 0.4 liters x 0.10 mol/liter = 0.04 mol

Volumen of acid in the bottle than contaiins 0.04 mol of acid: V = #moles/M = 0.04 mol/12.1 mol/liter = 0.003306 liters = 3.306 ml

Then you need 3.3 ml of acid from the bottle and 396.7 ml of pure water to get 400 ml of acid 0,1 M

$\boxed {\boxed {\sf Physical \ change}}$

Explanation:

A chemical change, as the name suggests, must result from a change in the chemical makeup and new substances are produced. A very common example is metal rusting.

A physical change can be observed without a change in chemical composition. No new substances are produces. Ripping paper and an ice cube melting are physical changes.

A rubber band stretching is a physical change. No new substances are made and the chemical makeup remains the same.

Answer:

physical

Explanation:

this is a physical action to create a change. does not involve chemicals or elements

What is true at STP? 1) Temperature is 295 Kelvin.
2) One mole of gas occupies a volume of one liter.
3) Pressure is 1.0 atmosphere.
4) Volume is 2.4 liters

Answers

The correct answer for the question that is being presented above is this one: "3) Pressure is 1.0 atmosphere." STP stand for standard temperature and pressure. The values of STP are 22.4 liters, 1mole, 1.00 atmospheres, and 273 kelvin. Under these conditions, all gases behave ideally or the same.
