Answer:
See below.
Explanation:
1. The water here is the solvent, and the 'sugar and fruit specific chemicals' are considered the solute. That is as the solute is the component dissolved in the solvent.
2. The collision theory states that the greater the collisions, the greater the rate of reaction. When powdered sugar is placed in the water (solvent) it occupies more surface area, resulting in more collisions that speed up the rate of reaction, compared to a cube of sugar - that occupies less surface area. Therefore, the powdered sugar dissolved faster.
3. Molarity describes the number of moles of a substance per unit of volume. The standard unit of volume is liter, giving you the standard units (mol/l). Molality describes the number of moles per unit of mass, typically kilograms (mol/kg).
The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent for molality, and moles of solute dissolved in liters of solvent for molarity. Molality is generally used for concentration.
i believe the answer is, b. heat energy is continuously added at each step. As energy is added, the molecular motion/kinetic energy increases, and matter changes state. In the last state, plasma, enough energy has been added to cause the atoms to disassociate into ions.
hope this is right! :33
Answer:
about 19 or 20 g
Explanation:
To do this, is neccesary to watch a solubility curve of this compound. This is the only way that you can know how many grams are neccesary to dissolve this compound in 50 mL of water to a given temperature.
Now, if you watched the attached graph, you can see the solubility curve of many compounds in 100 g of water (or 100 mL of water). So, to know how many do you need in 50 mL, it's just the half.
So watching the curve, you can see that at 20 °C, we simply need between 35 g and 40 g. Let's just say we need 38 grams of NH4Cl to be dissolved in 100 mL of water.
So, in 50 mL, it's just the half. So, we only need 19 g or 20 g of NH4Cl at 20 °C, to dissolve this compound in water.
What is the percent yield if 4.65 g of copper is produced when 1.87 g of aluminum reacts with excess copper (II) sulfate? 2Al (s) + 3CuSO4 (aq) → Al2 (SO4)3 (aq) + 3Cu
TLC means Thin Layer Chromatography. It is a method that can best be described as "Affinity-Based" used in the separation of compounds that are in a mixture.
<h3>What is unreacted p-nitrobenzaldehyde?</h3>
Unreacted p-nitrobenzaldehyde is simply an organic aromatic compound that contains a nitro group para-substituted to an aldehyde. in this case, if it is unreacted, that means it is the same as before the chemical reation.
Note that the question is missing key information hence the general answer.
