(b) A sample of cheap self-rising flour contains 10.0g of cream of tartar and 5.0 g of baking soda. What volume of CO2 at room temperature and pressure would be released when the reaction between the two components proceeds to completion?​

The correct answer is "false"

Zinc contains about 30 protons 

Pcl5 + 4 h2o = h3po4 + 5 hclthe ratio is 1: 5 for  pcl  and hcl, 1 mole of pcl produces 5 moles of hclmolecular weight of pcl5 is: 31 + (5 x 35.5) = 208.5above we have 75.5 / 208.5 = 0.36 moles so this will produce0.36 x 5 = 1.81 moles of hcl.
