3 1) Number Properties i) Integers Numbers‚ such as -1‚ 0‚ 1‚ 2‚ and 3‚ that have no fractional part. Integers include the counting numbers (1‚ 2‚ 3‚ …)‚ their negative counterparts (-1‚ -2‚ -3‚ …)‚ and 0. ii) Whole & Natural Numbers The terms from 0‚1‚2‚3‚….. are known as Whole numbers. Natural numbers do not include 0. iii) Factors Positive integers that divide evenly into an integer. Factors are equal to or smaller than the integer in question. 12 is a factor of 12‚ as are 1‚ 2

Is Green house gases and global warming a real threat? Human beings are about to encounter the worst catastrophe apart from the bubonic plague which characterized the middle ages. This threat is the global warming. So many people are still on the debate on whether global warming is taking place and also on the potential effects it has on the environment. However‚ most scientists and researchers are in agreement that‚ global warming is already taking place and it is going to increase uncontrollably

Using Stoichiometry to Determine Gases Produced in a Reaction Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness is often alloyed with aluminum. Magnesium is also used in racing car wheels called MAG wheels. Many car-manufacturing companies will use magnesium and aluminum because of the lightness of the metal. Both of these metals are reactive with acids. The most common acid in they

removes harmful materials from exhaust gases before they are released into the environment or atmosphere. There are two types of scrubbing methods. There is wet and dry scrubbing. Both systems work in similar ways and have the same end result. That is to change a toxic chemical into something less toxic or non-toxic. Now scrubber systems rely on a chemical reaction with a sorbent (which is a material that sorbs another substance or A substance that has the property of collecting molecules of another

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

Quiz 6 Key 1. Neither N2 nor O2 are greenhouse gases because A. N2 and O2 react with one another‚ producing N2O2 when exposed to infrared radiation. B. their overall electric charge distribution does not change when they vibrate. C. infrared radiation causes their bonds to break. D. their atmospheric concentrations are not changed by human activity. Remember that greenhouse gases have a change in bond structure when interacting with infrared radiation. 2. Find the molar mass of ethanol

Life is a blessing. Life is a gift. Life indeed is a tour‚ and it is God‚ who acts as our own tour guide. Many have considered life as a gift‚ a gift from the Almighty Creator that all of us must be thankful of. Life is a gift that we should appreciate‚ respect‚ and took good care of. We should also be thankful to our parents because‚ they become the instruments of God to give us life here on earth and to let us experience different things.I still remember the quote that says‚ you have to live

2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the tendencies of a

In this essay I am going to explain why and what trespassing is and the legal and moral consequences of trespassing and what property rights are. Most importantly‚ I am going to tell you why I should respect the property rights of others. "Trespassing" is a legal term that can refer to a wide variety of offenses against a person or against property. Technically‚ a person violates the law against trespassing by knowingly going onto someone else’s land without consent. "Knowledge" may be inferred
