Is there a difference between a homogeneous mixture of hydrogen and oxygen in a 2:1 ratio and a sample of water vapor? Explain.
You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
friend of yours reads that the process of water freezing is exothermic. This friend tells you that this can’t be true because exothermic implies “hot,” and ice is cold. Is the process of water freezing exothermic? If so, explain this process so your friend can understand it. If not, explain why not.
Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.
The flashlight in the photo does not use batteries. Instead, you move a lever, which turns a geared mechanism and finally results in light from the bulb. What type of energy is used to move the lever? What type or types of energy are produced?
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
Name two halogens. Look up each of your choices in a dictionary, in a book such as The Handbook of Chemistry and Physics, or on the Internet, and make a list of their properties. Also list any uses of each element that are given by the source.
3. Carefully put an egg in a glass half filled with vinegar. Replace the vinegar on the second day. Place the covered glass with the vinegar and egg in a safe place for one week without disturbing it. After one week, pass a light through the egg using a flashlight. N.B. DO NOT BOIL AND EAT THE EGG. A. Results and observation. Equation: HC2H3O2 + CaCO3 calcium acetate + H20 + carbon dioxide B. Calculation: If 9.02 x 1024 particles of vinegar (HC2H3O2)HC2H3O2) is added to 16.5 moles of eggshell (CaCO3) and 6.35 moles g of calcium acetate is formed. What are the (a) theoretical yield, (b) actual yield and (c) percent yield
The mass of magnesium used in this experiment is critical to determining the moles of hydrogen gas generated. The analytical balances used in Chemistry 1A labs are very sensitive to point that touching materials with your fingers before measuring them can affect the measurements. The balances are sensitive enough to detect dirt and oils from your fingers transferred to the magnesium. Would your experimental value of R increase or decrease if the mass of magnesium measured was artificially high due the touching it with your hands? Increase Decrease

ichiometric Calculations Practice Turn off Show units and Show numerical result. Press New question, and use what you have learned to solve another stoichiometry problem. For each problem, list the units given, the units asked for, and the solution. The problems in the Gizmo are given in random order, so you may have to press Next question several times to see a new problem. Note: Each term in the equation is either a solid (s), liquid (), gas (g), or an aqueous solution (aq). If you are stuck, try ode of the following hints: If the given unit is grams (or liters or particles), convert from that unit to moles first. Then, convert to moles of the answer substance. If the answer unit is grams, liters, or particles, find the number of moles of the answer substance first. Then, convert the moles of answer substance to the desired unit. If you have a calculator, try to calculate the solution to each problem yourself before turning on the Show numerical solution checkbox.
