Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O.Suppose 61. g of hydrobromic acid is mixed with 44.1 g of sodium hydroxide. Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits. I keep getting this problem wrong because of the sig. digits, dont round till the end because if it is off by 0.1, it will be incorrect.
Combustion of hydrocarbon such as heptane produces carbon dioxide, a greenhouse gas. Greenhouse gases in the earths atmosphere can trap the suns heat, raising the average temperature of the earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. A. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid heptane into gaseous carbon dioxide and gaseous water. B. Suppose 0.260kg of heptane are burned in air at a pressure of exactly 1 atm and a temperature of 18°C. Calculate the volume of carbon dioxide that is produced in liters. Round your answer to three significant digits.
A reaction for the reduction of copper is shown below (as an unbalanced reaction - that's how I will almost always give you reactions. ALWAYS check to see if a reaction is balanced before you use it. You balanced it in the last question; make sure you have that right before you start calculating!), you are given 3.000 tonnes (3.000x103 kg) of copper oxide. You check and find that you have 404.9 kg of ammonia gas available to you. What mass (in kilograms) of copper(II) oxide will remain unreacted after all the ammonia has been consumed and the reaction stops? CuO(s) + NH3(g) → Cu(s) + H2O(g) + N2(g)
