Lucas Capobianco-Hogan 9/18/14 Chemistry Honors Density Lab Materials: Scale Graduated Cylinder Calculator Unknown Substance Procedure: Weigh the graduated cylinder with no liquid in it. Measure out a volume of 5mL of the unknown substance into the graduated cylinder. Subtract the mass of the graduated cylinder with liquid in it by the mass of the empty graduated cylinder to calculate the mass of the liquid. Find the density of the liquid by using the formula mass/volume. Measure out a volume of 7mL of the unknown substance into a graduated cylinder. Repeat steps 3 and 4. Measure out a volume of 10mL of the unknown substance into a graduated cylinder. Repeat steps 3 and 4. Conclusion:

Chemistry-Nuclear Packet Name:__________________________________ Hour:____ Page ? PAGE ?1? Chemistry A Nuclear Chemistry ? Worksheet #1 : Radioactivity Chemical reactions involve changing one substance into another substance by rearranging atoms. However, during a chemical reaction atoms of one element cannot change into atoms of another element. The reason this change cannot occur is that chemical reactions only involve an atom's electrons ? the nucleus remains unchanged.

Atomic mass mass of an atom in atomic mass units An atomic mass unit is equal to? One twelth the mass of one carbon-12 atom The average atomic mass is equal to? atomic mass on the periodic table Isotopes are atoms of the same element with a different number of ___ and so they have different ___ 1) neutron 2) masses Mole Is a counter and relates to mass.* It is similar to a dozen. *It can count the number atoms/molecules/particles. Molar Mass *is the mass of one mole of the substance. *g/mol = atomic mass of the element *molar mass of an element contains mols of atoms Avogadro's number particles/atoms/molecueles > moles *6.022x10^23 Percent Composition Mass of element/ mass of compound x 100 Tell how much an element contributes to the mass of the compound

Placing gummy bears into an unknown solution in order to differentiate between hypertonic, hypotonic, and isotonic solutions. Gummy Bear Lab Experiment West Broward High School Biology 1 Honors Submitted by: Anabel Vazquez Blk#4 October 6, 2015 Problem: Are the gummy bears hypertonic, hypotonic, or isotonic to the unknown solution? Research: Hypertonic means that the inside of the gummy bear has a lower concentration of water molecules than the solution, causing water to enter the gummy bear. Hypotonic means that the inside of the gummy bear has a higher concentration of water molecules than the solution, causing water to leave the gummy bear.
