If 309 grams of potassium combines with 228 g chlorine gas, how many grams of the single product will be formed? What are the LR
lisov135 [29]

The amount of KCl that would be formed will be 478.8 grams

<h3>Stoichiometric calculations</h3>

From the equation of the reaction, the mole ratio of K to Cl_2 is 2:1.

Mole of 309 g potassium = 309/39 = 7.92 moles

Mole of 228 g Cl2 = 228/71 = 3.21 moles

Thus, potassium is in excess while Cl2 is limiting.

Mole ratio of Cl2 and KCl = 1:2

Equivalent mole of KCl = 3.21 x 2 = 6.42 moles

Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams

. In lab we used 40 ml of 6M NaOH in making soap.<br>How many moles of NaOH was in this volume?​
Firdavs [7]

Hey there!:

Molarity of NaOH = 6 M or 6 mol/L

Volume of NaOH = 40 mL

Therefore , number of moles of NaOH:

40 mL  =( 6 mol / 1000 mL)*40=

6/ 1000 * 40 =>  0.24 moles of NaOH

Hope this helps!

On what basis can mixtures be classified as solutions suspensions or colloids
FinnZ [79.3K]

Answer:

A mixture is classified as a solution when there is an homogeneous mixture of the two or more substances involved in a given medium.

A mixture is classified as a suspension when there is a heterogeneous mixture of undissolved particles in a given medium.

A mixture is classified as a colloid (false solution) when the individual solute Particles are larger than the particles of true solution, but they are not large enough to be seen by the naked eye. The solutes can scatter light rays.
