how many "particles in solution" will form from each sucrose (C12H22O11) molecule added to water? Explain.

I don't understand where I am supposed to start... What do I need to know to do this problem?
thank you

You need to know that C12H22O11 is sucrose. It is held together by covalent bonds and doesn't ionize when placed in water. Therefore, sucrose will dissolve in water forming one particle per molecule. Something like NaCl, an ionic compound, dissolves in water forming two particles per molecule; i.e., a Na^+ and a Cl^-. MgCl2, an ionic compound, dissolves in water forming three particles per molecule MgCl2; i.e., one Mg^2+ ion and two Cl^- ions. Covalent molecules other than sugar, if they dissolve in water, dissolve as the molecule; therefore there is only one particle per molecule. I hope this helps.

Sodium sulfide does, indeed, form three particles, but your explanation is not right. Sodium sulfide is Na2S (you wrote NaS). When it dissolves it forms 2 Na^+ and 1 S^2- for three particles. (Don't confuse the number of ions with the charge. The sulfide ion is -2 charge but it's only one ion.)

Na2S ==> 2Na^+ + S^2-

For the futures question, I think that will work.

Okay thank you for the explanation. For soduim sulfide(NaS), will it form 3 particles in solution? Na+1 and S-2 so would that give you 3?

For future reference, for these problems should i first see what type of bond it creates, then if it dissolves in water to get my answer?

Well, you've come to the right place for some guidance, my friend! As for where to start, let me help you out.

To understand how many particles form from each sucrose molecule in water, we need to look at the molecular formula of sucrose, which is C12H22O11. Each molecule of sucrose is composed of 12 carbon atoms (C), 22 hydrogen atoms (H), and 11 oxygen atoms (O).

When sucrose is dissolved in water, it undergoes a process called dissociation. This means that the sucrose molecule breaks up into its individual parts, or particles. In this case, each sucrose molecule will break up into 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

So, the total number of particles formed from each sucrose molecule added to water would be 12 carbon atoms + 22 hydrogen atoms + 11 oxygen atoms = 45 particles.

I hope that clears things up for you! If you have any more questions or if you need a good joke to lighten the mood, just let me know!

To solve this problem, you need to have a basic understanding of the concept of mole, Avogadro's number, and the idea of particles in a solution.

1. Mole: A mole is a unit of measurement used in chemistry to express the amount of a substance. One mole of any substance contains 6.022 x 10^23 particles.

2. Avogadro's number: Avogadro's number (6.022 x 10^23) is a fundamental constant in chemistry that represents the number of particles (atoms, molecules, or ions) in one mole of a substance.

3. Particles in a solution: A solution is formed when a solute (substance being dissolved) is mixed with a solvent (substance doing the dissolving). When a solute is added to a solvent, the solute's particles disperse and mix uniformly with the solvent particles, resulting in a homogeneous mixture.

Now, to determine the number of particles formed from each sucrose molecule added to water, you need to consider sucrose's molecular formula (C12H22O11) and calculate how many individual particles are in one molecule.

Here's the step-by-step explanation:

1. Determine the total number of atoms in one sucrose molecule: One molecule of sucrose contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

2. Calculate the total number of atoms: Add up the number of carbon atoms, hydrogen atoms, and oxygen atoms. In this case, we have:

12 carbon atoms + 22 hydrogen atoms + 11 oxygen atoms = 45 atoms

3. Calculate the number of particles: Since each atom in a molecule is considered a particle, multiply the total number of atoms by Avogadro's number:

Number of particles = Total number of atoms in one molecule × Avogadro's number

Number of particles = 45 atoms × 6.022 x 10^23 particles/mol

4. Perform the calculation: Multiply the number of atoms by Avogadro's number to get the number of particles.

Once you have performed this calculation, you will get the answer to the question of how many particles in the solution will form from each sucrose molecule added to water.
