How many moles Al are required to produce 300. g Al2O3? 4Al + 302 → 2Al2O3 5.88 mole 13. 100. g Al reacts with excess O2 to produce 150. g Al2O3 according to Calculate the theoretical and percentage yield.
LABORATORY REPORT Activity 2: Twitch Contractions and Summation Name: Instructor: Date: PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases, the force of contraction: MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable 2. Independent Variable 3.
During arm extension, what type of contraction would the triceps brachii be exhibiting: concentric isotonic contraction, eccentric isotonic contraction, isometric contraction. concentric isotonic contraction 7. As muscle load is increased, which muscle fiber type is recruited first, second, and last? First is the slow oxidative fiber, then is fast oxidative glycolytic fibers, and last is fast glycolytic fibers. 8.
Question : (TCO 7) Pritchard Company manufactures a product that has a variable cost of $30 per unit. Fixed costs total $1,500,000, allocated on the basis of the number of units produced. Selling price is computed by adding a 20% markup to full cost. How much should the selling price be per unit for 300,000 units? 6.
328.0 grams o C. 439.0 grams o D. 48000 grams 4. 4. Based on the image, what can you infer about the mass of the object being measured? o A. The mass is exactly 255.0 grams.
Given: wages, salaries, and fringe benefits = $5 trillion; profits = $400 billion; interest = $300 billion; rent = $100 billion; and depreciation = $700 billion. How much is National Income? 7. Given: wages, salaries, and fringe benefits = $5.7 trillion; profits = $500 billion; interest = $250 billion; rent = $150 billion; and indirect business taxes = $400 billion. How much is National Income?
Managerial Accounting 1B (Power Time and Haltom Business Case Study) A Powertime, Inc., produces and sells electric lawn mowers for $250 each. The variable costs of each mower total $160 while total monthly fixed costs are $22,500. Current monthly sales are $100,000. The company is considering a proposal that will increase the selling price by 10%, increase total fixed costs by 10% and increase unit sales to 500 units per month. Sales units Sales Selling price: $250 100,000 400 Selling price: $250(0.1)= $275 137500 Variable cost: $160 variable cost: $160 Fixed cost: 22500 Fixed cost: 22,500(0.1)= 24750 1.
PREDICTIONS 1. Exceeding the threshold depolarization at the trigger zone ______ the likelihood of generation of action potential.Increase 2. Action potential amplitude: doesn’t change with the distance 3.

After adding $15,300 to the $15,000 in savings, the cash flow for year 2 would equal $30,300. For year 3, the depreciation expense would equal $85,000 * .15, or $12,750. The tax on the year 3 deprecation would then be $12,750 * .40, which equals $5,100. After adding $5,100 to the $15,000 in savings, the cash flow for year 3 would equal
