How many molecules in 4.10 mol H2O?

Chemistry

1 answer:

Shtirlitz [24]3 years ago

8 0

Answer:

2,47 * $10^{24}$ (molecules)

Explanation:

Avogadro's number is a very important relationship: 1 mole = 6,02 * $10^{23}$ atoms, molecules, protons, etc.

To convert from moles to molecules, multiply the molar amount by Avogadro's number.

4,1 mol * 6,02 * $10^{23}$ ≈ 24,7 * $10^{23}$ = 2,47 * $10^{24}$ (molecules)

Therefore the third answer is correct

Which best describes the particles in a gas when the temperature rises from 23 °C to 46 °C?

mariarad [96]

I think the correct answer is b. Temperature is proportional to the average kinetic energy so when temperarure rises so will the average kinetic energy. I hope this helps. Let me know if anything is unclear.

you are given a solution of lead nitrate. use any of the solution used in this experiment to form a white precipitate of lead ch

Vesnalui [34]

We have as a reagent a salt, lead nitrate (Pb(NO3)2), and an unknown solution that gives us as a product lead chloride (PbCl2). That is, the solution must contain chlorine.

If a chlorine solution is used we will have the following reaction:

$Pb(NO_{3)2}+2Cl^-\rightarrow PbCl_2+2NO^-_3$

So, with a chlorine solution, we will have a white precipitate of lead chloride.
