I am throwing a party which means I need to order pizza. There will be 10 people at the party (including me). I assume each person will eat 3.000 slices of pizza. The place I am ordering from has 10.00 slices per large pizza and charges $21.00 for a pizza. They also have a medium pizza with 8.00 slices and costs $20.00 a pizza. In order to feed everyone 3.000 slices, how much money would each person need to contribute (round to the nearest cent) in order for each person to spend the least amount of money? This pizza place is also magic, so you can buy fractions of a pizza (assume you are buying the exact amount of pizza you need and are charged accordingly). We are ignoring tax and ignoring that the slices will not actually be equal in size.

Don't forget the dollar sign in your answer like this: $8.76

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
