if a weak acid was contaminating a pond, would the fish absorb more or less of...
Calculates the dimensions for various fish pond configurations. Specifically, the program will calculate the volume for the pond in cubic feet, the surface area of the sides and bottom of the fish pond, and the area of a 2-foot wide border around the edge of the pond.Ponds come in predefined sizes and shapes. There are: - circular ponds, diameter: 5 feet - square ponds, side: 5 feet - rectangular ponds, dimensions: 4 feet by 7 feet - ovoid ponds, dimensions:...
Would you classify tartaric acid as a weak or a strong acid? Why?
Also, can you explain why it would either become more or less spontaneous please. 3. Balance the following redox reactions, adding H20 and H+ (or OH) as needed. Predict for each one whether the reaction would become more or less spontaneous at higher pH. Procedures for balancing redox reactions in acid or base can be found in Chapter 4.1 of our Wikibook (a) MnO4 (aq) + N2O(g) (6) Cr2O72- (aq) + S2032- (aq) c) H2O2 (aq) + HI (aq) —...
Which of the following vitamins would be more difficult to absorb from the digestive tract if the person had a disease that interfered with their ability to absorb fats from their diet. vitamin C or Folate?
1. A fish pond is to be dug into a lawn so that it w hold 10 kL of water (note that 1 kL 1 m3). For æsthetic reasons, the pond is to be cylindrical in shape, with vertical sides. For practical reasons, the pond cannot be more than 1 m deep and must be at least 0.3 m deep (a) (i) Write an expression for the volume V of the pond in terms of its radius r and depth...
A pregnant mother who has been eating more fish to obtain a good supply of n-3 fatty acids read a newspaper article indicating that all ocean fish are contaminated with mercury. She is concerned about the safety of her baby. Review the current advisory of the FDA (www.fda.gov and Box 9-4) regarding the consumption of fish by pregnant women. How would you advise her? Develop some practical menu suggestions to help her.
Which would be a prediction for the first hypothesis, "Aggressive fish get more food and grow faster than more passive fish"? A. If the fish are isolated and given the same to food, they should grow at the same rates. B. if the fish are isolated and given the same access to food, they should grow at different rates C. if the fish are assessed for their aggressiveness/passiveness they should all score about the same. D fish that are smaller...

Question: In the figure below, titration curves for strong acid with strong base and weak acid with strong base are shown. Compare the shapes of these curves early in the titration for three different cases: titration of a strong acid, titration of a weak acid with a lower pKa, and titration of a weak acid with a higher pKa. Discuss with the class why the titration curve for weak acids increase more rapidly early in the titration than do stronger...
please help l, will rate! thabk you!! Why does a solution of a weak acid and its conjugate base act as a better buffer than does a solution of the weak acid alone? The presence of both the acid and the base provides a significant concentration of both an acid and a base, making it harder to change the pH A solution of a weak acid alone has no base present to absorb added acid. The presence of both the...
