Menthol, from oil of mint, has a characteristic odor. The compound contains only C, H, and O. If 89.6 mg of menthol burns completely in O2, and gives 252 mg of CO2 and 103 mg of H₂O, what is the empirical formula of menthol? (Enter the elements in the order: C, H, O.) Empirical formula:

d. Agt (6 pts) When an unknown hydrocarbon (Hy) is combusted and 6.309 g CO2 is produced. What is the empirical formula hol c. Na+ e. Cu²+ in excess oxygen, 3.444 g H₂O of the compound?

Use only 1 decimal point for atomic masses. Determine the yield (amount of product) of HCI(g) if 2.6 g of NCI3(g) is reacted in excess H2(g) by the following reaction: NCI3(g)+3H2(g)-->3HCI(g)+NH3(g)

When mixed, these compounds react as follows. This is balanced as written: Na2CO3(s) + 2 CH3CO2H(aq) --> CO2(g) + H₂O() +2 NaCH3CO2(aq) One of the products is the gas carbon dioxide (CO₂). Based on this reaction, for every ONE molecule of sodium carbonate (Na₂CO3) that reacts, how many molecules of GAS will form? 01 3 O N

The first step in the reaction of Alka–Seltzer with stomach acid consists of one mole of sodium bicarbonate (NaHCO3) reacting with one mole of hydrochloric acid (HCl) to produce one mole of carbonic acid (H2CO3), and one mole of sodium chloride (NaCl). Using this chemical stoichiometry, determine the number of moles of carbonic acid that can be produced from 33 mol NaHCO3 and 77 mol HCl.HCl. moles of carbonic acid :  ____________________mol   Which of the two reactants limits the number of moles of H2 CO3 that can be made? 1. HCl 2. NaHCO3   How much excess reactant remains after the reaction? excess reactant : ___________________mol

and chlorine 8) A 25.8 gram sample of aqueous hydrogen chloride decomposed into hydrogen gas of chlorine gas were collected. What is the percent yield of this reaction? 2 HCl(aq) → H,(g) + Cl,(g) Calculate the theoretical yield of chlorine from 25.8 g HCl (grams to grams) gas. 13.6 grams а. E5.0 124 b. Calculate the percent yield. 80.
