Chemistry Final Study Guide Matter as anything that has mass and takes up space. Significant figures refers to digits that were measured. When rounding calculated numbers‚ we pay attention to significant figures so we do not overstate the accuracy of our answers. Rules: -All nonzero digits are significant. -Zeroes between two significant figures are themselves significant. -Zeroes at the beginning of a number are never significant. -Zeroes at the end of a number are significant if a decimal

Google Glass: Wearable Technology to the Next Level Abstract Google glass is a type of wearable technology with an optical head-mounted display (OHMD). It was developed by Google with a goal of producing mass-market ubiquitous computers. It looks like a pair of eyeglasses‚ except‚ the lens of the Google glass is a user-interactive display and supports Wi-Fi and Bluetooth connectivity. It was primarily designed to take phone calls‚ send texts‚ take photos and videos and deliver search results.

Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which

Micro Electro-Mechanical Systems Micro Electro-Mechanical Systems (MEMS) is the integration of mechanical elements‚ sensors‚ actuators and electronics on a common silicon substrate using microfabrication techniques. MEMS are a hot area of research because they integrate sensing‚ analyzing and responding on the same silicon substrate hence promising realization of complete systems-on-a-chip. As MEMS are manufactured using batch fabrication techniques similar to IC technology‚ MEMS are expected

Rampal Power Plant: Myths debunked The power plant in Rampal in Khulna near Sundarbans is a major development for the country but for the protestors‚ it’s a threat to the Sundarbans environment and also for the people who live there. The commentators of Rampal are environmentalists‚ scientists‚ and experts. Firstly‚ an important fact pushed by advocates that Rampal is 14 KM far from Sundarbans which contravenes the preconditions saying projects must be outside a 25 KM radius from the outer periphery

Structure and bonding Ionic bonds are chemical bonds formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between an metal and a non-metal. The metal loses an electron or electrons form its highest energy level becoming a positively charged Ion and the non-metal gains an electron or electrons in its highest energy level‚ becoming a negatively charged Ion. Covalent bonds are strong bonds between two non-metal atoms. A covalent bond forms when two
