Scenario Three Read the following extract: "Atmospheric ions are electrically charged particles which occur naturally in the atmosphere. They form in the upper atmospheric layers mainly because of the action of ultraviolet radiation from the sun, as well as in lower atmospheric layers as a result of radioactive radiation and cosmic rays. These cause ionisation of neutral molecules or atoms. As a result, ions are formed. These ions almost instantaneously combine to form molecules with ionic bonds." The extract mentions 'ions'. Explain what these are in tems of their electronic structure, and how this is different from an atom. The extract mentions 'lonic bonds'. Explain what these are, and how they form in terms of electron structure.

2. a) The oxidation number of an atom is typically the same as the charge of its common ion, therefore O is usually -2. Because magnesium oxide is a neutral compound, what must the oxidation number of Mg be? b) Neutral magnesium nitride that can sometimes be made as a byproduct of this reaction. What is the formula for this ionic compound?
1. Give reasons why the helium atom is smaller than the cesium atom. 2. A student got a problem wrong. They were asked, “How many grams of MgCl2 (molar mass = 95.21 g/mol) are needed to make 3.16 L of a 0.500 M MgCl2 solution?” The correct answer is 150. but the student got 1.58. What mistake did the student make? 3. To solve the following problem what is the reason you must subtract the vapor pressure of water, 24 torr, from the total pressure, 747 torr in order to solve the problem? “A 500.0-mL sample of H2 gas is collected over water at 298 K and 747 torr. What volume would the dry H2 gas occupy at STP? (Given: the vapor pressure of water at 298K is 24 torr).” By the way, the answer is .436 liters. NOTE: I am not asking you to solve this problem. I am asking the reason for subtracting the vapor pressure. If you simply solve the problem, you will get no points.
3) Show your calculations clearly. Suppose you are provided with a 36.55 g sample of potassium chlorate. a. What mass of oxygen should theoretically be released upon heating? b. What mass of potassium chloride residue should theoretically be left over after heating?
Write the correct chemical formula.
sodium fluoride and aluminum sulfate Write a balanced molecular equation, including all physical states. Write a balanced total ionic equation, including all physical states and charges for individual ions.Write a balanced net ionic equation, including all physical states and charges for individual ions.
Write balanced chemical equations for each of the following descriptions of a chemical reaction. You do not need to include the phases of the reactants or products. IMPORTANT NOTE: Before attempting to balance the equations, you must first convert the compound names into the correct chemical formulas. If you begin to struggle with that, you may wish to go back to Chapter 4 and re-work naming problems. Calcium reacts with chlorine to produce calcium chloride. (Recall that chlorine is one of the diatomic molecules that are referred to by their element's name).
When each of the following pairs of aqueous solutions is mixed, does a precipitation reaction occur? If so, write the formula and name of the precipitate. (Type your answer using the format CO2 for CO2. Type NONE in the blanks if there is no precipitation reaction.) (a) lead(II) nitrate + potassium bromideformula: name:
Ammonium perchlorate (NH, CIO) is the solid rocket fuel that was used by the U.S. Space Shuttle and is used in the Space Launch System (SLS) of Artemis rocket. It reacts with itself to produce nitrogen gas (N₂), chlorine gas (C1₂), oxygen gas (O₂), water (H₂O), and a great deal of energy. What mass of oxygen gas is produced by the reaction of 3.73 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits. 0 X

A) Enter the balanced chemical equation for the reaction of 2-bogusopropanoic acid with KOH. B) Enter the balanced equation for the ionization of 2-bogusopropanoic acid in water.
Conduct Internet research to learn how airbags work in automobiles. Take notes on your research. Then write one to two paragraphs explaining what causes airbags to inflate when a car is involved in an accident. Sodium azide (NaN3) is a substance that can be used to inflate airbags. An electrical impulse causes the sodium azide to decompose, producing elemental sodium and nitrogen gas. Write the balanced chemical equation for this reaction.
Look at the structural formula of the organic compounds below, name them and give a detailed analysis of their possible physical and chemical properties.
