Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic solution‚ to the acetic acid‚ which is an acidic solution‚ a neutralization reaction

brought Hitler to power.” To what extent do you agree with this statement? From 1929 to 1933‚ Hitler’s rise to power was exponential. Many factors had helped him gain power in Germany; those included Hitler’s personality and of course‚ the political and economical issues that had arise during that period of time‚ helping him gain wide support. Although‚ both factors had helped and are significant to Hitler’s success‚ circumstance‚ compared to personality‚ had helped Hitler gain power‚ to a larger extent

SESSION TEN LANGUAGE AND POWER (2): POWER BEHIND DISCOURSE Main points in this session: 1. Power behind discourse: Standard language 2. Power behind discourse: discourse types as ‘effects of power’ 3. Power and access to discourse The idea of ‘power behind discourse’ is that the whole social order of discourse is put together and held together as a hidden effect of power. Fairclough (1989) = three aspects of ‘power behind discourse’‚ i.e. of hidden effects of power: 1. Standard language

There are major differences that separate base pay from incentive pay. Some employers may choose to offer compensation as base pay only‚ while others offer base pay plus incentive pay. This is often the case for professional sales positions for example. Base pay is the rate of monetary compensation given from employer to employee not including overtime or bonuses. Incentive pay‚ (which for the scope of this paper has been designated lump sum bonuses paid annually) is a monetary gift provided to an

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base‚ depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts‚ so it won’t change your experiments at all. It goes like this: 2H2O --> H2O + H+ + OH- --> H3O+ + OH- See how the hydrogen ion was transferred? Most of the

Elements of Power (Slide 4) Power is fundamental‚ and it comes from many sources‚ such as intelligence‚ money‚ information‚ and hard work. Bertrand Russell said that power is just as fundamental a concept in social science as energy is in physics. Although people often speak of power as a bad thing‚ it is neither good nor bad by itself. Rather‚ it is the way we use power that determines whether it is harmful or beneficial. For that reason‚ aspiring leaders must be fully aware of power and its
