Research studies have found that the price elasticity of demand for bread is equal to -0.40 and the price elasticity of demand of butter is equal to -1.13. Holding everything else constant, if the price of bread and the price of butter each increase by 10 percent: (a) Will the revenue from sales of bread increase or decrease? (b) Will the revenue from sales of butter increase or decrease?
Use and modify some/all the reactions provided to form the indicated overall reaction according to Hess' Law. • If a reaction is not used in your Hess' Law process, include that indication by multiplying the reaction by "0" • If no modification is needed and the reaction is applied as written below, include that indication by multiplying the reaction by "1" • Use whole numbers and simple fractions (such as "2" or "1/2", not 0.5) and negative signs (such as "-2") where needed Then calculate and report the enthalpy change (in kJ) for the overall reaction in the indicated blank, including units with your written value and rounded to 1 decimal place.

(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. Phenolphthalein is a weak acid that is naturally pink. Rheology is the science that deals with the flow of fluids and the deformation of solids. 2. In the experiment on the rusting of metals, the ferricyanide’s blue coloration is an indication that no chemical reaction occurred after its use. Prussian blue is the color produced by the reaction of ferricyanide with the phenolphthalein. 3. When steel is continuously and consistently exposed to air, oxygen, and water, aluminum oxides will be formed on its surface. In the Philippines’ old coins, the metal commonly found in all of the coin denominations is nickel. 4. Galvanized steel is steel coated with tin. A polymer is a type of metal. 5. Corrosion is the same as rusting, and these terms may be used to refer to the wearing away of all metals by the…
(4d-202) A buffer solution is made by mixing H3PO4 and NaH2PO4 in water. How does this buffer system neutralize an addition of 5 mL of 0.45 M NaOH? Choose one of the options below. • The H3PO4, as a weak acid, will neutralize the added NaOH • The NaH2PO4, as a weak base, will neutralize the added NaOH • The H3PO4, as a weak base, will neutralize the added NaOH • The NaH2PO4, as a weak acid, will neutralize the added NaOH For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Cyclopropane (CH2)3 was burned to carbon dioxide and liquid water, as represented by the equation (CH2)3(g) + 9/2O2(g) = 3CO2(g) + 3H₂O(1) The heats of combustion of (CH2)3, carbon, and H₂ are, -500.0, -94.0 and -68.0 kcal mol-¹, respectively. The heat of formation of propylene, CH3CH=CH₂ is 4.9 kcal/mole. Calculate the heat of isomerization (in kcal mol-¹) of (CH₂)3 to propylene.
