I have to solve for the values of A and B in this equation. We were told to solve it as two equations, two unknowns using the densities and viscosities of acetone and water and I'm not sure how to approach this. The density for water was 0.995g/mL and for acetone it was 0.791 g/ml. The viscosity of water was 0.892 mpas and for acetone it was 0.295 mpas. The temperature this occurred at was 24.9 degree Celsius.

An ostwald viscometer was used to determine the time of flow of syrup at 20°C Data of water: Time of flow: 0.23 sec Density at 20°C: 0.998 g/cm3 Viscosity: 0.0101 poise Data of Syrup: Time of flow: 1.42 sec Density at 20°C: 1.153 g/cm3 1. What is the fluidity of water? 2. What is the Viscosity of syrup? 3. From the computed Viscosity of syrup, what will be its kinematic Viscosity? Show complete solution.

Which organic liquid has: Molecular weight = 79.53g/mol Density = 0.7708 g/ml Viscosity = 1.39 mPa.s index of refraction = 1.420

Imagine you have 3 beakers of water. The water temperature in beaker 1 is 0°C, in beaker 2 is 24°C and in beaker 3 is 45°C. If you place same amount of potassium permanganate crystals into these 3 beakers, predict what would happen to the crystals in these three beakers. Compare the predicted relative diffusion rate in these beakers, explain why.

TRUE OR FALSE When cohesion is greater than adhesion, a concave appearance of the liquid in a tube is evident. if water has no ability to form hydrogen bonds, it would be gas at room temperature. The attractive interaction between an ion and the induced dipole is called ion-induced dipole force. A polar molecule placed near an atom causes distortion of the electron cloud of the atom resulting to a dipole. Polarizability prevents gases containing non polar molecules to condense. Hydrogen bond is stronger than covalent bond.

Choose the correct statement and best answer that explains the difference in viscosity.

Chemistry 5. You melt the substance and de-coloration occurs. Unfortunately, you weren’t paying attention and miss the melting point. Should you start over or re-melt it? Or both are options ‘okay’? 6. When measuring the melting point of a substance, it suddenly disappears. What has happened? Can you still measure the melting point? If so, how? 7. We should not re-use a sample in a capillary tube for melting point measurement. Why not? 8. It takes significant amount of time for the melting point apparatus to cool down before next measurement if your new sample has a lower melting point than your previous one. What can you do to reduce this time in between measurements when many samples of different melting points are used?

[ Select] Which has lower boiling point? [ Select] Which has higher surface tension? [Select] Which has higher viscosity? ✓ [Select] hexanol hexane

which of the following would have the highest viscosity at a temperature and pressure where all are liquid? Rn, He or Ne?

1. Look up the viscosities of the three test liquids in a text book or on the Internet. How is Time (s) for Brass Bead to Reach Test Tube Bottom (Table 8.1) related to viscosity? As viscosity increases the time it takes for the bead to fall through the liquid increases. ) The time it takes for the bead to fall through the liquid is not related to viscosity. As viscosity increases the time it takes for the bead to fall through the liquid decreases.

Select the statements that correctly describe the term viscosity. This quantity is low for substances that flow readily. This quantity is high for molasses and glycerol. Viscosity can be defined as a substance's ability to resist flow. The viscosity of each substance is a constant value that will never char about us careers privacy policy terms of use contact us help P00 4 F5

Dynamic equilibrium can be defined as         rate of dissolution < rate of deposition         rate of dissolution > rate of evaporation         rate of dissolution > rate of deposition         rate of bubbling > rate of dissolving         rate of evaporating = rate of condensing

The time for water to flow through an Ostwald pipet at 20°C was 298.8 seconds. The density of water at 20°C is 0.9982 and the density of a sample of olive oil is 0.910 g/cm3. The viscosity of water at 20°C is 1.002 cp and the viscosity of the olive oil is 84 cp. How long will it take for the olive oil to flow through the same pipet at 20°C?

At room temperature, what is the viscosity of drinking water, water with a 10% salt solution, and water with a 1% salt solution?..
