Camels store the fat tristearin (C57H110O6) in their hump. As well as being a source of energy, the fat is a source of water, because of the following respiration reaction:    2 C57H110O6 (s) + 163 O2 (g) à 114 CO2 (g) + 110 H2O (l) What mass (g) of water can be made from 1.0 kg of fat?

The reaction for producing glucose in plants, called photosynthesis, is   6CO2+6H2O−→−−lightC6H12O6+6O2 6CO2+6H2O→lightC6H12O6+6O2    If a plant produces 5.81 mol C6H12O6,5.81 mol C6H12O6, how many moles of CO2CO2 are needed? moles CO2CO2:

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. In the first step, nitrogen and hydrogen react to form ammonia: N,(0) + 3 H,(9) → 2 NH,(9) ΔΗ-92. k In the second step, ammonia and oxygen react to form nitric acid and water: NH,(9) + 20,(9) → HNO3(g) + H,O(g) AH=-330. kJ Calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. Round your answer to the nearest kJ. ?

When you have an "upset stomach", most people consume a chemical known as an antacid. Antacids contain the chemical Al(OH)3 which reacts with stomach acid (HCI) in the reaction below. This reaction, between an acid and a base, is commonly called a neutralization. For your convenience, the molar mass of each substance is shown below their formulas (in purple). Use this information to make the requested calculation: (antacid) (stomach acid) Al(OH)3(s) + 3 HCI(aq) --> AICI3(aq) + 3 H20() 78.006 36.461 133.341 18.016 How many moles of stomach acid can be neutralized by 3.60 mol of antacid?

Copper (II) sulfate (CuSO4) can be used to control algae growth. Aqueous CuSO4 solutions that come in contact with the surface of galvanized (zinc-plated) steel pails undergo the following reaction: CuSO4(aq) + Zn(s) ---> Cu(s)+ ZnSO4 (aq) How many grams of zinc would react with 454 g (1 lb) of CuSO4 (159.61 g/mol) ?

Aqueous solutions of ammonia 1NH32 and bleach (active ingredient NaOCl) are sold as cleaning fluids, but bottles of both of them warn: “Never mix ammonia and bleach, as toxic gases may be produced.” One of the toxic gases that can be produced is chloroamine, NH2Cl.Another toxic gas that can be produced is nitrogen trichloride, NCl3. What is the oxidation number of N in nitrogen trichloride?

Phosphoric acid, a mild acid used among other things as a rust inhibitor, food additive, and etching agent for cavity repair by dentists, can be made from elemental phosphorus in a two step process. In the first step, phosphorus and oxygen react to form diphosphorus pentoxide: →+P4s  5O2g  2P2O5g In the second step, diphosphorus pentoxide and water react to form phosphoric acid  H3PO4 : →+P2O5g  3H2Ol  2H3PO4l Suppose the yield of the first step is  66.%  and the yield of the second step is  62.% . Calculate the mass of phosphorus required to make  2.0kg  of phosphoric acid. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

In a reaction to produce NaF, 3.50 g of HF and 1.26 of Na2SiO3 are reacted according to the following: Na2SiO3 (s) + HF (aq) →H2SiF6 (aq) + NaF (aq) + H2O (l) (a) Balance the equation.   (b) Calculate the theoretical yield of NaF.   (c) If 0.792 g of NaF is formed, calculate the percent yield.

The Apollo 13 mission astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide can remove carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. The astronauts have a 5 kg container of sodium hydroxide on the ship. The reaction to neutralize the air, remove carbon dioxide with sodium hydroxide is shown below CO2(g) + 2NaOH(s) ⟶⟶ Na2CO3(aq) + H2O(l)   The astronauts have 2 days left before they land on earth. You know that there are three astronauts, and each astronaut emits roughly 500. g of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? Calculate how much sodium hydroxide is required to remove all the carbon dioxide from the three astronauts.  Be sure to show all your work!

Because of the toxicity of mercury compounds, mercury(I) chloride is used in antibacterial salves. The mercury(I) ion Hg22+ consists of two bound Hg+ ions.How many grams of mercury(I) chloride are needed to saturate 4900 km3 of water (the volume of Lake Michigan)? (Ksp = 1.5 × 10−18) .
