What is the "mass per volume" percent of a household bleach product? I believe the question is asking for a calculation but I do not know how to proceed
You have standardized the NaOH solution that has a concentration of 0.05418 M. You are given a bottle of vineaga(acetic acid) with an unknown concentration.
the exhaled air contains 6.2% H2O and 15.3% O2 by volume. How many moles of H2O are expelled from the body each minute? How many moles of O2 are absorbed by the body each minute?
In coffee, how much would the boiling point (in C) of the water be raised by the addition of 0.2 g of caffeine (C8H10N4O2) to 5.0 L of water in making this so much coffee
Nylon undergoes depolymerization when heated in aqueous acid. Propose a reaction mechanism that accounts for this fact, using curved arrows to symbolize the flow of electrons.
calculate the energy, in joules and calories, lost when 75.0 g of water cools from 86.4 degrees celsius to 2.1 degrees celsius
Ammonia reacts with diatomic oxygen to form nitric oxide and watervapor. When 40.0g of ammonia and 50.0 g of oxygen are mixed and allowed to react, which is the limiting reagant? 4NH3 +5O2--> 4NO + 6H2O
what is the enthalpy change corresponding to the melting of 2.5 moles of H2O? what is the system? What is the surrounding? In what direction does the heat flow? Is the process endothermic or exothermic?
Calorimeters and heat capacity, If 2.500 g of Mg is burned in a constant volume calorimeter with a heat capacity of 1.10 kJ/degrees Celsius containing 1.500 L
the mass spectrum determined the molecular weight of mehtyl salicylate to be 125.15 g/mol. What is the molecular formula of methyl salicylate?
First determine the number of moles of rm Na^+ using the given molarity and volume. Next, use the chemical formula to determine the number of moles of rm Na_3PO_4 needed. Finally, convert moles to grams using the molecular weight of the compound.
Write the structures of the organic products that will be formed when methyl benzoate is treated with lithium aluminum hydride and the reaction mixture is worked up with aqueous acid.
