Wine goes bad soon after opening because the ethanol  CH3CH2OH in it reacts with oxygen gas  O2 from the air to form water  H2O and acetic acid  CH3COOH , the main ingredient of vinegar. What mass of oxygen gas is consumed by the reaction of 8.11g of ethanol?

Consider a small bird of mass 30 g. What is the minimum mass of glucose that it must consume (and burn) to fly up to a branch 10 m above the ground?

Silicon tetrachloride (SICI4 ) can be prepared by heating Si in chlorine gas: Si(s) + 2C12(g) -> SiCl2(1) In one reaction, 0.507 mole of SiCI4 is produced. What mass (grams) of molecular chlorine were used in the reaction? Choose the nearest answer. MW SICI4 = 169.9 g/mol; MW CI = 35.453 g/mol (A) 36 grams (B) 72 grams 27 grams D) 63 grams

Hw.28.   What mass of precipitate (in g) is formed when 45.5 mL of 0.300 M Li₃PO₄ reacts with 54.0 mL of 0.200 M CrCl₃ in the following chemical reaction? Li₃PO₄(aq) + CrCl₃(aq) → CrPO₄(s) + 3 LiCl(aq)

The human body burns glucose (C6H₁2O6) for energy according to this chemical reaction: C6H12O6 +60₂-6CO₂ + 6H₂O The products of the reaction are carbon dioxide (CO₂) and water (H₂O). Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500. mL of air, which is typically enriched to 4% CO₂ and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 1.00 kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO₂ is 2.0 kg/m³. 0 ☐ ☐x10 X

How many grams of water are produced in this reaction? NH4NO3(s) —> N2O(g) + 2H2O (I)

CCalculate the moles of product V. d-calculate the mass of V formed in grams. eWhich of the reactants is the limiting reagent? Given that:- (V=50.94g/mol, Ca = 40 g/mol, O = 16 g/mol).

Consider the following reactions:CoO (s) + CO (g) D CO2 (g) + Co (s) Kc(1) = 490.2 CoO (s) + 2 H2 (g) D 2 Co (s) + 2 H2O (g) Kc(2) = 4.5 x 103a. Write the overall equation for the reaction of hydrogen gas and carbon dioxide gas to produce carbon monoxide gas and steam.

Limestone is typically 50.0% (w/w) CaCO3. How many grams of CaCO3 are present in a limestone sample weighing 1.2 kg?

A new method being developed for water treatment uses chlorine dioxide, ClO2, instead of chlorine. One procedure for obtaining chlorine dioxide is to pass Cl2 (g) through a concentrated solution of sodium chlorite, NaClO2. The other product obtained is NaCl(aq). If the reaction has a yield of 97%. What mass of ClO2 is produced per liter of 2.0M NaClO2(aq) treated by this procedure?
