no need to explain just give me a number fir each box
Consider the following reaction: 2 Al + 6 HBr + 2 AlBr3 + 3 H2 When 1.61 moles of Al reacts with 4.96 moles of HBr, how many moles of H2 are formed? What is the limiting reactant? For the reactant in excess, how many moles are left over at the end of the reaction? For decimal answers, include the zero (ex. 0.99). Make sure you have the...

Congratulations! You have just been hired as a researcher by the PRUB Chemical Company Because of the large number of people eating spicy foods (and often eating them too fast), this company has asked you to develop a new antacid. They have given you some information, but the rest you must discover for yourself. Your boss has suggested that aluminum hydroxide may be effective as an antacid. This...

You will be observing a reaction in this lab. As with most reactions, this reaction occurs by the breaking of some bonds in the reactants and the formation of new bonds in the products. During the reaction, the gas that is produced will fizz away. After the reaction is complete, one of the products can be removed. Then you will determine the mass of the other product this will be your actual (or experimental) yield. You will compare this value...

All multiple parts to the same problem, thank you! :)
Solution Stoichiometry: We need to make a 0.250 M sodium carbonate solution. We will use a 100.00 mL volumetric flask. How many grams of solid sodium carbonate should we add to the flask to make the solution? Use 105.99 as the molar mass, report correct sig figs, and use g as the unit. Solution Stoichiometry: We need to make a 0.200 M calcium chloride solution. We will use a 100.00...
