Problem: Article: Your body uses the oxygen you inhale to react with the proteins, fatty acids, and carbohydrates you ingest. One of the results of this reaction is the carbon dioxide you exhale. In contrast, plants and some forms of bacteria take carbon dioxide from the air and, with energy supplied from sunlight, make simple sugars (which are carbohydrates). Life on Earth is based on the element carbon. To burn something requires a spark, a fuel source, and an atmosphere to burn it in. The oxygen in our atmosphere readily reacts with other substances; put it with burning carbon, and you get carbon dioxide. Calcium oxide (CaO), also known as quicklime, can be produced by burning limestone, which contains calcium carbonate (CaCO3). The CO2 is driven off, leaving the calcium oxide. (For this reason, it is also called burnt lime.) The carbon and oxygen that make up CO2 are found in a number of chemicals and minerals classified as carbonates or, when hydrogen is also present, bicarbonates. Reactions with other chemicals can release CO2 into the air or mix it with water to form carbonic acid (H2CO3). Some of the possible reactions include the following:  Hydrochloric acid and calcium carbonate. Hydrochloric acid (HCl) is the acid found in the human stomach. Calcium carbonate (CaCO3) is found in limestone, chalk, eggshells, pearls, and coral, as well as some antacids. When the two chemicals are mixed, calcium chloride and carbonic acid are formed, and the carbonic acid breaks down into water and carbon dioxide. Vinegar and baking soda. Vinegar is a solution of acetic acid (C2H4O2), while baking soda is sodium bicarbonate (NaHCO3). Mixing them produces water, sodium acetate, and CO2, usually in a foamy reaction. Methane and water vapor. This reaction is performed industrially to extract hydrogen by using steam at high temperatures. The methane (CH4) reacts with the water vapor (H2O) to produce hydrogen (H2) and carbon monoxide (CO), a deadly gas. The carbon monoxide is then mixed with water vapor at lower temperatures to produce more hydrogen and turn the carbon monoxide into safer carbon dioxide.  Yeast and sugar. When yeast is added to sugar in solution, as in the instructions in Part One, it forces the sugar to break down and give off CO2. The reaction also produces ethanol (C2H5OH), the form of alcohol found in alcoholic beverages. This reaction is called fermentation.
Summary: Exhale. Burn something with carbon in it. Mix carbon-containing chemicals.

Problem: Article: Don't share with anyone else, as you can spread radioactive particles to them. In fact, it's best to designate a separate bathroom for yourself during this time, if at all possible. Don't share hand towels in the kitchen, either. Even being near a person can transfer radiation from you to them, so you must avoid contact as much as possible. Sleep in a bedroom by yourself, and don't let anyone else use the bed even when you're not in it. While you're still a source of radiation, stay at least 3 feet (0.91 m) away from other people at all times. They should only come closer for very short periods, such as a minute or two if it's absolutely necessary. Staying 6 feet (1.8 m) or farther away is even better, particularly with children and pregnant women.  It's best to be in a different house away from children and pregnant women if at all possible. In fact, avoiding contact with pregnant women for 20 days is best, while you shouldn't get closer than 6 feet (1.8 m) to a child in the first 3 days. Limit car rides with other people. If you need a driver, sit in the back seat in the opposite corner from the driver. Staying in a hotel puts others, such as the cleaning staff, at risk since they do not know they are handling radioactive material. They will also wash the linens with the other guest linens, potentially putting other guests at risk, too. If you need to separate yourself, have other household members stay in a hotel instead.
Summary: Keep a towel, hand towel, and washcloth for your use only. Sleep by yourself. Maintain distance from other people. Avoid staying in a hotel.

Problem: Article: Start by writing your improper fraction. Then, divide the numerator by the denominator — in other words, just do the division problem that the fraction is already set up for. Don't forget to include the remainder.  Let's follow along with an example. Let's say that we need to turn the fraction 7/5 into a mixed number. We'll start by dividing 7 by 5, like this: 7/5 → 7 ÷ 5 = 1 R2 The whole number part of your mixed number (the big number to the left of your fraction) is the whole number answer of your division problem. In other words, just write the answer of the division problem without the remainder. In our example, since our answer is 1 R2, we would leave off the remainder and just write 1. Now, we need to find the fraction part of the mixed number. Put the remainder from your division problem in the numerator and use the same denominator from your original improper fraction. Put this fraction next to your whole number and you have your mixed number!  In our example, our remainder is 2. Putting this over our original denominator (5), we get 2/5. We put this next to our whole number answer (1) to get our final mixed number, like this:  1 2/5. Mixed numbers look good on paper and are easy to read, but they're not always the best choice. For example, if we're multiplying a fraction and a mixed number, our work will be a lot easier if we convert the mixed number back into an improper fraction. To do this, just multiply the whole number by the denominator and add it to the numerator.  If we wanted to convert our example answer (1 2/5) back to an improper fraction, we would do it like this:  1 × 5 = 5 → (2 + 5)/5 = 7/5
Summary:
Divide the numerator by the denominator. Write the whole number answer. Make a fraction from the remainder and the original denominator. To get back to an improper fractions, add the whole number to the numerator.
