Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is

ADD/ADHD not Just a Kid Problem What do you know about ADD or ADHD? How can ADD/ADHD affect a student if they are not treated in time? "Attention deficit disorder (ADD) and Attention deficit hyperactivity disorder (ADHD) are condition listed as developmental disorder in the classification manual for psychiatric‚ psychological‚ and mental disorder." (Steinberg & Othmer 2) When people hear about ADD/ADHD they assume that only kids and teens have this problem‚ but there have been some cases that

Lenin’s view on the “party”: He demanded strong authority at the top‚ by which the central committee would determine the doctrine (or “party line”) and control personnel at all levels of the organization. He thought the party would strengthen itself by purges‚ expelling all but the most fundamental disagreements

These two ratios measure the proportion of funds the company has raised from creditors as opposed to owners. They indicate how much “leverage” the firm has in its capital structure. The basic trade-off a company makes in determining the “right” ratio (i.e.‚ capital structure) is between the risks inherent in taking on fixed

The Solutions of Substance Abuse Among Teens and Young Adults Teens and drug use is always a popular problem being discussed everywhere‚ and now it’s becomimg more and more serious among teenagers in the United States‚ the number of reported drug abusers has gradually increased. It is more evident that solutions are needed to help young adults with this issue. 1. Drug treatment interventions 2. Community input and 3. Family support could help solve young adult’s problem with substance abuse

work on more reliable solutions in relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve

In addition to a change in concentration‚ a change in temperature and a catalyst variable was also introduced to conclude whether or not their presence affected the overall speed of the reaction. In order to determine the effects of these variables‚ several iodine and hydrogen peroxide reactions were prepared‚ (all at varying temperatures‚ volumes‚ and concentrations)‚ and reacted until the solutions color turned from clear to dark blue.

The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester. The hydrogen peroxide is kept in a thin‚ small glass vial in the middle of the stick‚ and the second chemical phenol oxalate ester is in the main body of the light stick. Bending the light stick in the middle causes the small glass vial of hydrogen
