Molarity = variety of moles of solute/liters the solutionnumber of mole of solute = molarity x liters of solutionPart (a): 30.00 ml that 0.100m Cacl2number of mole of CaCl2 = 0.1 x 0.03 = 3x10^-3 moles1 mole that CaCl2 contains 2 moles of chlorine, thus 3x10^-3 moles of CaCl2 consists of 6x10^-3 moles of chlorinePart (b): 10.0 ml of 0.500m bacl2number of mole of BaCl2 = 0.5 x 0.01 = 5x10^-3 moles1 mole of BaCl2 includes 2 mole of chlorine, as such 5x10^-3 moles of BaCl2 includes 10x10^-3 moles of chlorinePart (c): 4.00 ml of 1.000m naclnumber of mole of NaCl = 1 x 0.004 = 0.004 moles1 mole the NaCl contains 1 mole the chlorine, because of this 4x10^-3 moles of NaCl includes 4x10^-3 mole of chlorinePart (d): 7.50 ml the 0.500m fecl3number of moles of FeCl3 = 0.5 x 0.0075 = 3.75x10^-3 moles1 mole that FeCl3 consists of 3 moles of chlorine, because of this 3.75x10^-3 mole of FeCl3 has 0.01125 moles of chlorineBased ~ above the over calculations, the exactly answer is (d)

Brian excreted 50ml of urine. He placed the urinometer into the cylinder and read the measured specific gravity at 1.027. 5 minutes later, that realized the he had actually forgotten to take it the pee temperature. When he took the temperature in ~ 24°c, the measured certain gravity to be at 1.031. What to be brian"s urine particular density?

Is a measure of the resistance to flow. A high liquid has actually a high resistance come flow and also flows slowly. The ancients thought everything in the people was made of 4 we now know that there are 94 normally occurring and scientists have actually created one more 24 i am certain they will produce even more. Love husband flows slowly because it has a high to flowing. A have the right to be be separated by physical way because the contains an ext than one pure substance and 2 pure substances space not chemically external inspection to each other. A cannot be be separate by physical means. All issue is comprised of all aspects are with the same number of protons. If it is just a single or countless bonded together, if all of them have actually the same number of protons, that is an element. In a piece of pure steel metal, every the are joined together, that piece of iron steel is called elemental iron. A single of iron is called elemental iron. A mixture has differences from place to place. We could need a microscopic lense to watch them or they can be evident to the unaided eye. There room surfaces separating it into various phases. A mixture is the exact same everywhere. It is uniform. There are no surface separating the into different phases. If different kinds of atoms (different elements) are bonded with each other by their electrons, that is dubbed a there are physical way of to isolation the various pure substances in a mixture and also there space chemical means of to isolate the different facets in a compound. 1. Aspect 2. Link 3. Mixture 4. Heterogeneous 5. Homogeneous 6. Pure problem 7. Atoms 8. Separation 9. Viscosity 10. Resistance
