The food we eat is degraded, or broken down, in our bodies to provide energy for growth and function. A general overall equation for this very complex process represents the degradation of glucose (C6H12O6) to carbon dioxide (CO2) and water (H2O): C6H1206 + 602 → 6CO2 + 6H2O If 856 g of C6H1206 is consumed by a person over a certain period, what is the mass of CO2 produced?

Ethanol, C,H,O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of 2-methylheptane, C3H18, is 1.306×10³ kcal/mol. How much energy is released during the complete combustion of 482 grams of 2-methylheptane ? kcal Assuming the same efficiency, would 482 grams of ethanol provide more, less, or the same amount of energy as 482 grams of 2- methylheptane v more less the same amount

Classify each chemical reaction: Reaction 2Na(s) + Cl₂ (g) 2NaCl(s) 2Li(s) + 2HCl(aq) 2LiCl(aq) + H₂(g) H₂CO3(aq) → H₂O(l) + CO₂(g) K₂SO₂(aq) + Ba(NO³)₂(aq) → 2KNO3(aq) + -BaSO (s) Type choose one choose one choose one choose one X S >

Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+B D →> Reaction 2 gives product D. The following facts are known about the two reactions: • Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑

01 04 in the balanced equation for the complete combustion of heptane, the coefficient for carbon dioxide is: Cu + O = CO + HO W

The following unbalanced equation illustrates the overall reaction by which the body utilizes glucose to produce energy: C6H12O6(s) + O2(g) → CO2(g) + H2O(l)   What is the conversion factor that allows for the calculation of moles of carbon dioxide based on moles of glucose?

2. If 550 mL of water changes temperature from 25.0°C to 28.0°C during the complete combustion of propane, determine the mass of propane that is combusted using the information in this question? C3H8(g) + 502(g) · 3CO2(g) + 4H₂O(g) + 2050 kJ

15. Titanium (IV) chloride is reduced by magnesium to produce titanium according to the following reaction. a. TiCla(s) + 2Mg(s) → Ti(s) + 2MgCl2(s) How many grams of TiCla(s) can be reduced to Ti by 2000.0g of Mg?
