Vinegar 2. Blood 3. Sea Water 4. Battery Acid 5. Fruit Juice Non-aqueous 1.Petroleum 2. Olive Oil 3. Stainless Steel 4. Air 5. Lubricating Oil solid solid mixtures sand and clay. alloys, such as Tin and lead form an alloy called solder. blacktop, concrete solid liquid asphalt salt/sugar in waterVinaigrette Salad Dressing, whole milk, vinegar, gasoline,antifreeze

Can someone help me with some science questions?
Q. 1. How does increasing the temperature of a solvent affect the solubility of a gas? 2. Explain why the temperature of water might increase when a solution forms. 3. Explain why crushing a solute increases the rate of solution. 4.Name and describe the three types of solutions. 5. Explain why oil does not dissolve in water. 6. Describe how you might increase the solubility of a solid in a liquid. 7. Explain how a solution can be both dilute and saturated. 8. Describe three different ways in which the concentration of a solution can be reported. 9. Define and give an example of an acid and of the base. 10.List the properties of acids and bases. Which of the properties of acids would you use to safely test whether an unknown… [cont.]

A. 1.decrease 2.some solutes are exothermic on dissolving 3.more surface area 4. saturated holds all it can unsaturated can hold more supersaturated is holding more than normal at that temp 5.like dissolves like 6.smaller particles, stir, heat 7.very little will dissolve 8.molarity, molality. gm/ml 9. HCl NaOH 10.Too many to list, but use litmus paper to test 11.gas bubbles, H2 gas and MgCl2 12.base,acid,base, salt

A. There is a difference between helping you and doing your homework. Why don't you try it, and someone can check it out? BTW: no reactions available for reaction questions.

Need help with Physics and Chemistry in Science?
Q. What is the density of Solid, Liquid, Gas and what is the movement of their molecules and what is their volume and shape? And also what is suspension, colloid, and solution? what are some examples? And how can u tell the difference between them? I know its alot to ask but my finals are tommorrow and I havent learned this stuff cause I moved a while ago and I need alot of help to cover much as i can. Thanks

A. There is no specific density for "solids" or "liquids" in general. Solids are the densest of the three and have the slowest molecular movement. Liquids are not quite as dense as solids and also have faster molecular movement. Gases are the least dense of the three and have the fastest molecular movement. Basically, the greater an object's density, the slower the speed of its molecules. (ex- you heat water, water molecules gain energy and move faster then become steam which is a gas. Gas is less dense than liquid). Go on wikipedia and look up the rest. You can easily find this information online.
