Explanation:
Sodium and potassium are in the same group on the periodic table because they both have similar number of valence electrons (1 electron) in their shells
Na = 2,8,1
K = 2,8,8,1
Carbohydrates. The digestion of carbohydrates begins in the mouth. The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide. As the food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place.
Determine the number of moles of citric acid.
n of citric acid = (30 mL)(1 L / 1000 mL)(1 mol/L)
= 0.03 mol of citric acid
It is seen in the equation that each mole of citric acid reacts with 3 moles of baking soda.
n of baking soda = (0.03 mol of citric acid)(3 mols baking soda/1 mol of citric acid)
n of baking soda = 0.09 mol of baking soda
mass of baking soda = (0.09 mol of baking soda)(84.00661 g/mol)
mass of baking soda = 7.56 g of baking soda
Answer: 7.56 g
