Activity 1 You have up to 45 minutes to do this activity. 1. Read the text and correct the punctuation errors. There are 3 capital letters, 2 apostrophes, 2 commas and 3 end of sentence punctuation markers missing from the text. What a waste Why should you care about the rubbish that you produce every hour here's why. Throwing anything away is a waste of the materials and energy used to makett. If we reuse and recycle instead we will not need to use as many of the worlds natural resources. At the moment, most waste in the Uk ends up in landfill sites which are large holes in the earth where rubbish is put. Although most of these sites are well managed, people dont usually like living near them. once a site is full, it is covered over to bury the rubbish and can no longer be used. There is very little space for new landfill sites, so we need alternative solutions for our waste.

#3 A. In the left margin on page 232 of the course textbook, or on slide 65 of the Chapter 10 lecture slides, you will find the general forms of the fractional composition equations for polyprotic acids. Use these to develop the fractional composition equations for a triprotic acid system and then plot $\alpha$ vs. pH for the components of the citric acid system. B. Use equations 10-11 and 10-12, adjusting them for the appropriate K values, to calculate the pH of a solution produced by dissolving 5.00 g of Na?HC (C³ is citrate) in 0.550 L of water. C. Explain why the pH values calculated in B differ or not. Does the pH calculated using Equation 10-11 make sense based on the fractional composition plot? D. Calculate the concentrations of each of the components in the solution described in B.

Distinguish the true statements from the false statements. True False Market failure occurs when external costs are present but not when external benefits are present. Market failure occurs when either external costs or benefits are present. Market failure is when free markets provide a suboptimal amount of goods and services. Government sometimes intervenes when market failure occurs. Market failure occurs when external benefits are present but not when external costs are present. Market failure can occur only in the presence of external costs.
