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

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

Consider these reactions: AH = -184.6 kJ Reaction 1: H₂(g) + Cl₂ (g) → 2HCl(g) 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 Use Reaction 1. Determine the mass, in grams, of chlorine gas consumed (with excess H₂) when 1,891.0 kJ of energy is released from the system. Answer: g (mass must be positive; round to nearest whole number)

Which of the following represents an endothermic reaction? O CH4 (g) + 202 (g) → CO2 (g) + 2H2O (g) + 890 kJ 2S02 (g) 25 (s) + 20, (g) + 376kJ O 2C2H6 (g) + 702 (g) → 4CO2 (g) + 6H2O(g) + 3120 kJ 2H20 (g) + 572 kJ → 2H2 (g) + O2 (g)

Consider these reactions: Reaction 1: H₂(g) + Cl₂(g) → 2HCl(g) Reaction 2: 20F₂ (g) → O₂(g) + 2 F₂ (g) Reaction 3: N₂(g) + 2O₂(g) → 2NO₂ (9) Use Reaction 1. AH = -184.6 kJ AH = -49.4 kJ AH = +66.4 kJ Determine the mass, in grams, of chlorine gas consumed (with excess H₂) when 1,861.0 kJ of energy is released from the system. Round to the nearest whole number. Answer:____ g

when a 0.55-g of olive oil is burned in a calorimeter the hear released increases the temperature of 360 g of water from 22.7 c to 36.4 c . what is the energy value for the olive oil in kcal/g?

According to the equation below, do the products have stronger or weaker bonds than the reactants? C (s) + 2H (g) → CH4 (g), ΔHrxn = -74.86 kJ/mol
