number 2 and 3 Only************************

Make sure to follow the following steps when solving the 5 problems below: - Write the chemical equation - Balance the chemical equation (you can find the tutorials for how to do this on the materials page) - Use the molar ratios (coefficients) to solve all 5 problems 1. The combustion of propane (C3H8) provides energy for heating homes and cooking food. How many moles of Carbon dioxide will be released if 16.3 moles of propane is used up? 2. Lithium reacts spontaneously with bromine to produce lithium bromide. If 2.5 moles of bromine gas are present at the beginning of the reaction, determine the number of moles of lithium bromide produced. 3. Sodium, which is a highly reactive shiny metal, reacts with chlorine, a toxic yellowish-green gas, to produce a safe chemical (sodium chloride) that we sprinkle on our food for taste. How many moles of the chlorine gas will be needed to produce 7.25 moles of sodium chloride? How many particles of chlorine gas would that be? 4. The exothermic reaction between liquid hydrazine (N2H2) and liquid hydrogen peroxide (H2O2) is used to fuel rockets. The products of this reaction are nitrogen gas and water. How many moles of water ore releosed when 6.2 moles of hydrozine are used up? How many molecules of woter would that be? 5. When hydrogen gas is cooled to sufficiently low temperatures, it condenses to form a liquid that can be used to power non-polluting vehicles in which its reaction with oxygen (from the air) yields an exhaust containing only water vapor (greenhouse gas that is short-lived in the atmosphere). If 136.5 moles of hydrogen are used up for a trip to cedar point, how many moles of water vapor will be released into the atmosphere? Show all of your work and post/upload it here by the end of the hour. You can use jamboard or several google drawings images, one for each
