count the number of shirts in your closet. The second way to quantify or measure matter is to determine its mass. For example‚ you can buy bananas by the pound. The third and last way to quantify or measure matter is to determine its volume. For example‚ people by gasoline by the gallon. Chemists use a unit that is a certain number of particles. This unit is known as the mole. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles

polyatomic ions). 1. Determine the Number of valence electrons in the Lewis Structure: One of the easiest ways to start drawing a Lewis Structure is to make a list of each atom in the structure and next to each atom record how many valence electrons it has and how many it needs to fill its valence shell. In covalent bonding the valence electrons in the molecule come from the valence electrons in the atoms that formed the bond. a. The number of valence electrons in any main group atom

Introduction The number π is a mathematical constant that is the ratio of a circle’s circumference to its diameter‚ and is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century‚ though it is also sometimes written as "pi. π is an irrational number‚ which means that it cannot be expressed exactly as a ratio of any two integers (fractions such as 22/7 are commonly used to approximate π; no fraction can be its exact value); consequently‚ its decimal

Inequalities Maths Compiled By : OP Gupta [+91-9650 350 480 | +91-9718 240 480] Exercise 6.1 Question 1: Solve 24x < 100‚ when (i) x is a natural number (ii) x is an integer Answer The given inequality is 24x < 100. (i) It is evident that 1‚ 2‚ 3‚ and 4 are the only natural numbers less than . Thus‚ when x is a natural number‚ the solutions of the given inequality are 1‚ 2‚ 3‚ and 4. Hence‚ in this case‚ the solution set is {1‚ 2‚ 3‚ 4}. (ii) The integers less than are …–3

universal precautions. Suppose the spread of a direct contact disease in a stadium is modeled by the exponential equation P(t) = 10‚000/(1 + e3-t) where P(t) is the total number of people infected after t hours. (Use the estimate for e (2.718) or the graphing calculator for e in your calculations.) 1. Estimate the initial number of people infected with the disease. Show how you found your answer. Answer: A total of 474 people would be initially infected. Equation: p(0)=10‚000/(1+3^3) ~ 474

concern on the minds of the drivers. Many people die every year due to reckless or careless driving. Driving safe is not a choice it is the law‚ but the law is broken and people suffer the affects of it. Driving drunk and texting while driving is the number one killer while in a vehicle. My perspective before turning sixteen was to drive with out any worries‚ but now because of the incident with my mother I realize driving safe is the right thing to do.

I chose to analyze Beethoven’s Piano Sonata number 15. Sonata number 15 is opus/work number 28. There are 4 movements in the work‚ but I chose to analyze the first movement. Beethoven was born on December 16‚ 1770 into a family of musicians ("Classical Net - Basic Repertoire List - Beethoven" pars. 1-2). Beethoven began writing music at a young age ("Classical Net - Basic Repertoire List - Beethoven" par. 4). He composed his first original Sonata in 1797 ("Classical Net - Basic Repertoire List -

Age is just a Number What is age? Does age define who you are? As a nurse in Long term care for fifteen plus years I have learned to look past the number found in the persons chart. I have learned when I as a caregiver look past that number that represents the date the Elder was born; the Elder too tends to look beyond that number and will follow along leading to experiences one might not think Elders of LTC facilities might still accomplish.

colors‚ red and blue‚ it is impossible to color the edges of the kn without forming either a red kp or a blue kq. In short we formulate it as kn[pic]kp‚kq (read as kn arrows kp‚kq). The smallest value of such n is denoted by r(p‚q)‚known as the Ramsey number. A famous example for the two color Ramsey theorem is k6 which arrows k3‚k3. To prove k6 [pic]k3‚k3‚ let’s put 6 points on a plane and call one of them v. There are 5 edges joining v to the remaining 5 points. Let’s color them red
