of steel wool into the test tube and measured the temperature again. We stored the test tubes on the test tube rack to observe the next day. A chemical reaction did occur in the lab. There were a color change and an odor change that was observed on Day 2 of the lab. On Day 1‚ the liquid was clear and the smell was very strong. On Day 2 of the lab‚ most of the liquid was gone but the color was a muddy color and the smell got milder‚ it wasn’t as strong as Day 1. Not only was there a color and odor

INTRODUCTION Genetic variations are the basic tools in the hands of breeders to develop new cultivars with better traits‚ like tolerance against various environmental stresses‚ resistance against pest and diseases and improved yield and quality. In field conditions‚ a number of abiotic stresses affect the crop plants. Abiotic factors generally disturb various cellular functions along with the complex metabolic pathways (Kassem et al.‚ 2004; Lee et al.‚ 2004; Popelka et al.‚ 2004). Drought is

Heats of Reaction Lab Report Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation. NaOH(s) ( Na+(aq) + OH-(aq) ΔH = -10.6kcal/mol NaOH(s) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -23.9kcal/mol Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -13.3kcal/mol Background: Energy changes occur in all chemical reactions; energy is either absorbed or released. If energy is released in

Full adder[edit source | editbeta] Schematic symbol for a 1-bit full adder with Cin and Cout drawn on sides of block to emphasize their use in a multi-bit adder A full adder adds binary numbers and accounts for values carried in as well as out. A one-bit full adder adds three one-bit numbers‚ often written as A‚B‚ and Cin; A and B are the operands‚ and Cin is a bit carried in from the next less significant stage.[2] The full-adder is usually a component in a cascade of adders‚ which add 8‚

What is the Full Employment Rate of Unemployment? Full employment‚ or the natural rate of unemployment‚ is considered to be consistent with a level of unemployment that predominantly comprises voluntarily unemployed workers. In other words‚ those members of the labor force who really want a job have one. Leaving the nuances of who is part of the labor force for the main text‚ the rate of unemployment consistent with full employment is a major issue for economic policymakers. Small differences
