Burning aluminum creates a white flame as the metal reacts with oxygen to produce aluminum oxide. How many moles of oxygen are needed to react with
7.5 moles of aluminum in the following reaction; 4 AI + 3 02 - 2 A1,0,?*

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.

Which of the following changes will decrease the total amount of gaseous solute able to be dissolved in a liter of liquid water? (2 points) decreasing temperature decreasing pressure decreasing surface area decreasing solute concentration
