2. Summarize the following description of a chemical reaction in the form of a balanced chemical equation?

= = == Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Water + Carbon Dioxide Equipment ---------

Why are spindle fibers important for mitosis? (5 points) Chromosomes use spindle fibers as pathways to daughter cells during mitosis.

Example problem: How many grams of carbon dioxide are produced when 20.0 g acetylene (C2H2) is burned?

Evaluate how the name of a muscle can distinguish its location, action, shape, and function. Select five different muscles to make this distinction.

25) Determine the oxidizing agent in the following reaction. Ni(s) + 2 AgClO4(aq) → Ni(ClO4)2(aq) + 2 Ag(s) A) Ni B) Ag C) Cl D) O E) This is not an oxidation-reduction reaction. 26) How many liters of hydrogen gas can be generated by reacting 9.25 grams of barium hydride with water at 20°C and 755 mm Hg pressure according to the chemical equation shown below? BaH2(s) + 2 H2O(l) → Ba(OH)2(aq) + 2 H2(g) A) 1.60 L B) 3.21 L C) 0.799 L D) 0.219 L 27) A gas mixture contains CO, Ar and H2. What is the total pressure of the mixture, if the mole fraction of H2 is 0.35 and the pressure of H2 is 0.58 atm? A) 2.1 atm B) 0.60 atm C) 0.49 atm D) 1.7 atm E) 0.20 atm

The purpose of this lab is to gain knowledge and understanding of the scientific principle of RER, using indirect calorimetry to measure caloric expenditure, including the caloric equivalent and to understand the concepts behind estimating oxygen consumption and caloric expenditure from heart rate, including the limitations. In addition the purpose was to learn skills of how to measure and graph the linear relationship between heart rate and VO2 and then determine the regression equation line and to estimate the caloric expenditure from VO2, heart rate, and caloric equivalent values.

The dissolving of CO2 in the reaction solution and the evaporation of water both effected the result of the analysis because they have a relation. The dissolving CO2 caused the evaporation of the water and the weight loss of CO2 was used to calculate the percent by mass of NaHCO3, so it has an effect on the graph and the way that it looks depending upon the dissolving of CO2.

Boyle’s Law was published by Irish scientist Robert Byles who discovered the law from acquaintance Richard Towneley who discovered it from family friend Henry Powers who discovered that PV=k. Charles Law was discovered by Jacques Charles who discover that V/T =k and Avogadro's Law was discovered by Amedeo Avogadro who discovered that V/n=k. Finally, Joseph Louis Gay-Lussac published in 1808 that P/T=k. And as a result, these Laws were all able to be combined into a single unified equation,

Initially, the rock salt partially dissolved in the drops of water. After several minutes, the salt was more dissolved, but had not completely dissolved. There were very fine grains of salt that were visible at the base of the water bubble that hadn’t dissolved.

The lime water turned into white opaque color, and gas bubbles and white precipitate was formed, as placed the open end of the gas delivery tube(reaction between Alka Seltzer tablet + water) into the limewater.

Notice the list of deliverables toward the end of the information. Part 1 includes deliverables 1-4.

= == CaCO3(s) + 2HCC(l) CaCl2 (aq) + H2O(l) + CO2

The next stage of my work is to carry out all the necessary calculations which includes:
