ANALYSIS Here is some additional information about almonds: The serving size for almonds is 1.00 servings 1.00 ounce Almonds are 48.9% by mass fat, 21.7% by mass carbohydrates, and 21.7% by mass protein On average, 1.0 gram of fat yields 9.0 Calories, 1.0 gram of carbohydrates yields 4.0 Calories and 1.0 gram of protein yields 4.0 Calories Use the measured mass of your almond, and the relationships given above to write equalities and conversion factors that can be used to solve dimensional analysis problems (refer back to steps #3 and #4 of the strategy discussed in the "Concept Connections" section). Write the equality first, in the left column. Use each equality to write 2 conversion factors in a fractional form in the right column.

1 ! QUESTION 10 The metabolism of one glucose with six oxygens to form six carbon dioxides and six waters releases 678 kcal per mole of glucose. Given this, which statement below is true? O Glucose metabolism is endothermic and the energy of the products (CO2 and H2O) are lower than the reactants (glucose and O2) O Glucose metabolism is endothermic and the energy of the products (CO2 and H₂O) are higher than the reactants (glucose and O2) O Glucose metabolism is exothermic and the energy of the products (CO2 and H2O) are higher than the reactants (glucose and O2) O Glucose metabolism is exothermic and the energy of the products (CO2 and H2O) are lower than the reactants (glucose and MacBook Pro C G Search or type URL A Q A K 2 W S #3 E D $ 4 R F do LO % 5 T 6 G Y & 7 H ☆ U * 00 8 9 O J K

Would the following reaction be endothermic or exothermic? Why? CH4 + O2 --> CO2 + H2O + Energy O Endothermic because energy is a product Endothermic because energy is a reactant O Exothermic because energy is a reactant O Exothermic because energy is a product

Both animals and plants rely on stored energy for survivalAnimals can store energy in the form of sugars from the consumption of other matter. Plants the other hand, utilize photosynthesis to produce sugar (glucose). Following storage, the sugars can then be used to provide energy for various functions within the organism. This is referred to as the burning of sugar shown in the chemical reaction below: C 6 H 12 O 6 (s)+O 2 (g) CO 2 (g)+H 2 O(g) 3. Complete the following questions based on the reaction above representing burning sugar: . Balance the chemical equation representing sugar burning (reaction above). b. What type of reaction(s) is/are being represented by the chemical reaction in part (a) ? . How would you prepare 40.00 of 0.250 M sugar solution (C 6 H 12 O 6 ) from a stock solution that is 1.25 M C 6 H 12 O 6 (aq)? ? Provide your answer in terms of of sugar stock solution and explain how you would dilute to the total volume. (HintHow many of sugar stock solution and how…

Consider these reactions: Reaction 1: H₂(g) + Cl₂ (g) 2HCl(g) AH-184.6 kJ Reaction 2: 20F2(g) O₂(g) + 2 F₂ (g) AH = -49.4 kJ Reaction 3: N₂(g) + 2O₂(g) · 2NO₂(g) AH = +66.4 kJ

heat content in the surroundings of an endothermic reaction decreases, because the energy contained in the products is lower than the reactants the reaction absorbs heat energy the energy contained in the reactants is lower then the products heat energy is destroyed during reactions

Determine Kc for the reaction 1 1 1 N₂(8) + 0₂ (8) + Br₂ (8) = NOBr(g) 2 2 based on the following information 2NO(g) = N₂(g) + 0₂ (8) NO(g) + Br₂(g) = NOBr(g) K=2.1x1030 C K = 1.4 C

Label both formulas shown in both reactions as anhydrates and hydrates.
