Answer:

CH3OH, NaBr, CaCl2, Cr(NO3)3

Based on disorderliness, the ionization strength gives the entropy.

CH3OH - Does not ionize, it's a solvent

NaBr- Ionizes intwo two ions

CaCl2- Ionizes to three ions 1Ca and 2 Cl ions

Cr(NO3)3- Ionizes to four ions

Explanation:

Here is the complete question:.

Rank the following solutes in order of increasing entropy when 0.0100 moles of each dissolve in 1.00 liter of water.

CaCl2, CH3OH, Cr(NO3)3, NaBr

yarga [219]
The answer is Make sure you are working with a properly balanced chemical equation.
Convert grams of the substance given in the problem to moles.
Construct two ratios - one from the problem and one from the chemical equation and set them equal. ...
Convert moles of the substance just solved for into grams. Step 1: Convert known reactant mass to moles. ...
Step 2: Use the mole ratio to find moles of other reactant. ...
Step 3: Convert moles of other reactant to mass. Balance the equation.
Convert units of a given substance to moles.
Using the mole ratio, calculate the moles of substance yielded by the reaction.
Convert moles of wanted substance to desired units.

Solid sodium reacts violently with water producing heat, hydrogen gas and sodium hydroxide. How many molecules of hydrogen gas a
nignag [31]
Find the number of moles of sodium you have: 
<span>n = m/M where m is your 20g of sodium and M is 22.99 g/mol. </span>

<span>Look at the stoichiometry of the equation - it's 2:2 when you are producing NaOH. So if you took 1 mole of Na, it'd produce 1 mole of NaOH (as the ratio is equal). </span>

<span>That means that your moles of sodium is equal to the moles of NaOH produced. Use the molar mass of NaOH - which is 39.998 g/mol along with your calculated number of moles to get the mass (the formula rearranges to m = nM). </span>

<span>This figure is the theoretical yield - what you would get if every last mole of sodium was converted into NaOH. </span>

<span>What you get in practice is the experminetal yield, and the percentage yield is the experimental yield divided by the theoretical yield - and then multiplied by 100%.</span>
