- True or false? Mixtures always result in a chemical reaction because they consist of two or more substances and thus combine to create a new product.arrow_forwardConsider equal volumes (say 1 L) of a given substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass based on the trend for the average substance. If the mass difference between samples is relatively small (10% or less), rank the items as equivalent. Rank from greatest to least mass. To rank items as equivalent, overlap them. • View Available Hint(s) Reset Help 1 L of substance in the solid phase 1L of substance in the gas phase 1L of substance in the liquid phase Greatest mass Least massarrow_forwardThese three statements about Substances A, B, and C are true: The average kinetic energy of Substance B is higher than that of Substance A.

- In Parts 1 and 2, you noticed some patterns about what kind of substances conduct electricity when dissolved in water, and also how melting points are related. Let's test this pattern by applying it to other substances. Consider the following substances: • Potassium Chloride: KCI • Octadecanol: C18 H380 • Dimethyl Sulfoxide: C2 H6OS • Lithium Bromide: LiBr 1. Based on the patterns you saw in the previous sections, which of those substances do you think will conduct electricity when dissolved in water?

Both jars have the same volume of water. He drops the sugar cubes at the same time and then observes how much of them dissolves in two minutes. What will be the result of Sam’s experiment, and which statement should he use as his conclusion? A A greater amount of sugar dissolved in hot water because temperature is directly proportional to the solubility rate of sugar in water. B Temperature does not affect the solubility rate of the sugar cube in water because sugar dissolves equally in both cold and hot water. C A greater amount of sugar dissolved in hot water because temperature is inversely proportional to the solubility rate of sugar in water. D A smaller amount of sugar dissolved in cold water because temperature is inversely proportional to the solubility rate of sugar in water.arrow_forward

- Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. mg of the powder are put into a very thin tube and heated. The powder begins melting at 66.2 °C. The temperature continues to rise as the powder slowly melts, and the last of the powder becomes liquid at 76.0 °C. Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is put into a beaker filled with 250. mL of water. The cube collapses into a small pile of orange powder at the bottom of the beaker. When this powder is filtered out, dried and weighed, it has a total mass of 29.9 g. If the experiment is repeated with 500. mL of water, the powder that's left over has a mass of 30.0 g. Is sample A made from a pure substance or a mixture?

Calcium carbonate (CaCO3) is in fact slightly soluble in water (0.001 g/100 mL). What effect will this have on NaCl from the mixture: will the "isolated" mass be greater than, equal to, or less than that in the sample? Selected answer will be automatically saved.
