These alternative substances will not be as effective in your Zippo lighter and may not work at all. For best results, go with a lighter fluid specifically designed for use with Zippo lighters. Flints will become damaged or worn over time, so they need to be replaced on a regular basis. Use Zippo brand flints for best results, since these are designed specifically to be used with Zippo lighters.

One-sentence summary -- Refrain from using butane or charcoal lighter fluid. Replace the flint every 1-2 months to keep your lighter working well.


In molecular orbital theory, bond order is defined as half of the difference between the number of bonding and antibonding electrons. Bond order = [(Number of electrons in bonding molecules) - (Number of electrons in antibonding molecules)]/2. Each electron that entered a bonding molecular orbital will help stabilize the new molecule. Each electron that entered an antibonding molecular orbital will act to destabilize the new molecule. Note the new energy state as the bond order of the molecule. If the bond order is zero, the molecule cannot form. The higher bond orders indicate greater stability for the new molecule. Hydrogen atoms have one electron in the s shell, and the s shell is capable of holding two electrons. When two hydrogen atoms bond together, each completes the s shell of the other. Two bonding orbitals are formed. No electrons are forced to move to the next higher orbital, the p shell – so no antibonding orbitals are formed. The bonding order is thus (2−0)/2{\displaystyle (2-0)/2}, which equals 1. This forms the common molecule H2: hydrogen gas.

One-sentence summary -- Know the formula. Know that the higher the bond order, the more stable the molecule. Consider a simple example.


For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c. What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides. In this example, the length of side a = 5, the length of side b = 5, and the length of side c = 5. This particular example is called an equilateral triangle, because all three sides are of equal length.  But remember that the perimeter formula is the same for any kind of triangle. In this example, 5 + 5 + 5 = 15.  Therefore, P = 15. In another example, where a = 4, b = 3, and c=5, the perimeter would be: P = 3 + 4 + 5, or 12. If the sides of the triangle are measured in centimeters, then your answer should also be in centimeters.  If the sides are measured in terms of a variable like x, your answer should also be in terms of x. In this example, the side lengths are each 5cm, so the correct value for the perimeter is 15cm.

One-sentence summary -- Remember the formula for finding the perimeter of a triangle. Look at your triangle and determine the lengths of the three sides. Add the three side lengths together to find the perimeter. Remember to include the units in your final answer.


The preferred style of title page depends on the type of book you're making.. If you intend on sending your book to a publishing house, the title page should be kept relatively basic. Make a title page that offers hint of what your book is about.  Stick to the basics of work title, name, date and contact info, all written in large enough font to be read easily at arms' length. With a creative venture however, the possibilities are endless. If you're visually artistic, drawing up a doodle to go with the title adds a sense of style. A title is obviously mandatory for any title page. No matter how adventurous you're getting with the title page design, make sure to make your title big and bold. Most of your favourite books-- from the pulpy fantasy fiction to the leatherbound classics-- probably have an attractive cover to them. While the common adage tells us not to judge a book by its cover, there isn't a book out there that hasn't been helped out if it's got an attractive look to boot. A sleeve should wrap around both sides of your book. If you're measuring out a sleeve yourself, consider the area of the book's spine as well.  For making a book at home, you should laminate a paper of your choice. Draw an appealing cover onto the sleeve if you have the artistic gusto for it, and don't forget to include important details like your name and the title of the book. Keep in mind that cover sleeves are only really worthwhile if you're doing a fully DIY approach and aren't trying to send it over to a publishing house. If your book is published professionally, the publisher will look after things like cover sleeve and artwork. Publishers come across a load of submissions every day. While some publishing houses may not have set requirements for the formatting of your manuscript, it is generally understood that the best looking submissions stand the best chance of acceptance. A poorly presented draft may be overlooked completely... even if the material itself is brilliant!  Adhere to standard font and size. Times New Roman in Size 12 is usually seen as the go-to format for text. Many professional writers prefer it because it's so easy to read.  Number your pages. Page numbering cannot be overrated when you're sending a manuscript. In case the pages are dishevelled, someone on the receiving end of your literary masterpiece is going to need to know which pages fit next to which. A page heading (with author and title) doesn't hurt either. Align and indent. Microsoft Word processors will align left and properly indent your pages by default, but in case you've dabbled with the settings at all, it's a good idea to make sure this is all in order before you print. Lastly, printing your masterpiece off is simple but essential to the plan, provided you've been doing any part of the project on a computer. Making sure that your ink cartridges are sufficient is a must, as people will become quickly aware as to the cause if the font  starts getting faint by the book's end. If you lack sufficient printing equipment at home, local schools, libraries and internet cafes should be able to help you relatively inexpensively. If you're sending the manuscript somewhere professional, it may not hurt to print using a slightly off-white  type of paper; this way, you'll stand out amidst the sea of generic manuscripts. If you are making a DIY book, binding a book together may be in the cards. There are many ways to go about it; if you're interested in arts and crafts, construction paper and glue are your friends. Find cardboard to glue onto the back ends of your pages as a spine, and tape your laminated cover sleeve around the book binding. Manuscripts for novels or non-fiction works that you intend on having published should not come with anything like this. Coil-binding the pages together with a basic title page will be enough. Anything too fancy or colourful in the package will detract from the potential seriousness of your work.
