Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Presidential powers are rolled back the office of the Presidency will lose credibility‚ power and respect. Public opinion regarding the president’s job performance influences presidential power; the higher the public approval‚ the more power the chief executive has to influence others within the political system‚ including Congress.

The Separation of Powers planned that the Constitution was originally only supposed to do one primary thing‚ “to prevent the majority from ruling with an iron fist.” Based on this and their experience that the framers went away from giving any kind of branch of the new government more power than they needed. Furthermore‚ the separation of powers provides a system of “shared power known as Checks and Balances.” The three branches that are created in the Constitution are Article 1 (Legislative Branch)

Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

The Separation of Powers is very important; it creates unique roles for each branch of government. There are three different branches‚ there’s the legislative branch‚ the judicial branch‚ and the executive branch. In the legislative branch‚ the laws are created‚ budgets are passed‚ and wars are declared. The judicial branch determines which laws apply to specific cases‚ reviews constitutionally of laws‚ and determines interpretations of laws. The executive branch enforces‚ or vetoes the laws that

Locke makes the argument that without a higher power or form of government man’s life and property could be in danger. A government could help secure freedoms and safety. In the state of nature many things are missing including a common law‚ no indifferent judge to determine differences‚ and a power to promote law. Men must create and agree with a form of law to make mankind peaceful with one another
