Consider the following unbalanced chemical equation. C5H12(/) + 02(g) → CO2(g) + H20(1) If 19.2 grams of pentane (C5H12) are burned in excess oxygen, how many grams of H20 will be produced? g H20
4-How many grams of water are produced when 30.6 g of hydrogen peroxide (H2O2) decomposes into oxygen gas and water?
The fuel you burn in your car's engine contains octane, C3H18. When octane is burned, the products are CO2 and H20. 2C8H18(1) + 2502(g) → 16CO2(g) + 18H20(g) Emissions testing is an important tool for protecting our environment and informs car owners if their car is emitting too much CO2 while driving. Using the balanced equation above, answer the following questions. If 10.22 g of octane (C3H18 ) and 17.35 g of oxygen are used in the reaction, what is the limiting reactant and how much CO2 is produced?
You are trying to synthesize a new compound that has potential anti-HIV activity – it could be the next drug used to treat HIV! It can be synthesized (made) from two commercially available starting molecules – call them “A” and “B”. They can be combined according to the following equation:A + 2B -> desired drug molecule. “A” has a molar mass of 85.0 g/mol, and “B” has a molar mass of 130.0 g/mol. You look these starting materials up in a chemical catalog, and here’s what you find:compound “A” costs $5000.00 per 5.0 gramscompound “B” costs $2500.00 per 1.0 gram(though you can buy either in any amount)a) You currently have $10000.00 to spend on starting materials. How many grams of each will you purchase to maximize the amount of drug molecule made? Show all work

Dichlorine monoxide, Cl,0, is sometimes used as a powerful chlorinating agent in research. It can be produced by passing chlorine gas over heated mercury(I) oxide according to this equation: HgO+Cl2 → HgCl, + Cl20 What is the percent yield, if the quantity of reactants is sufficient to produce 8.90 g of Cl,0 but only 2.10 g is obtained? Answer in standard notation to the nearest tenth of a percent
