NaHCO3​ (s) is commonly called sodium bicarbonate or baking soda. When NaHCO3​ is heated abeve 110∘C, but not heated to excessively high temperatures, it has been observed that both H2​O(g) and CO2​ (g) are evolved by some chemical chanse, and that after this decomposition reaction is complete, a white solid residue remains. Among possible reactions. the two following unbalanced reactions seem the ones that are most lively to explain these facts: How can we decide which of the two possible reactions is the one that actually occurs? What is the identity of the white solid? Is it sodium carbonate or sodium oxide? You are to choose between restions (A) and (B) on the basis of your laboratory results, which will irvolve heating a weighed sample of sodium bicarbonate in a crucible and weighing the residue left in your crucible after hesting. From the mass of the solid product, you should be able to decide if the product of the reacticn is Na2​O (s) or Naa2​COO3​ (s).
Find the molar masses of the following: NaHCO3​ Na2​CO3​ Your answer should be a number plus the appropriate units. Do not use spaces and makes sure your answer has the correct number of significant figures. Atomic Masses in amu for elements: Hydrogen =1.008, Helium =4.003, Nitrogen =14.007, Carbon =12.011, Oxygen = 15.999, Neon =20.180, Sodium =22.990, Silicon =20.085, Calcium =40.08 Question 5 1 pts What kind of personal protective equipment (PPE) should be worn when working with high concentration hydrocloric acid (HCl)? For the safety data sheet visit Flinn Scientific SDS for hydrocloric acid ω′′. Nothing. HCI is safe to work with. Goggles, gloves, closed toed shoes, and clothing that covers the body. Only gloves, because you dor't haveto worry about splashing or spilling this chemical. Only gogeles because you only have to worry about splashing your eyes.
