2024年6月17日 · To find the moles of NaHCO3 in a 3.00 g sample, first calculate the molar mass of NaHCO3 (84.01 g/mol). Then, divide the mass of the sample by the molar mass to obtain the moles of NaHCO3.

Question: Baking soda is sodium bicarbonate, NaHCO3, and vinegar is primarily acetic acid, HC2H3O2. When baking soda is added to vinegar, the resulting reaction produces a tremendous amount of gas, as shown in this video. NaHCO3(s) + HC2H3O2(aq) rightarrow Complete this equation for the reaction of NaHCO3(s) with HC2H3O2(aq). Include phase symbols.

2024年11月20日 · The equivalent weight of NaHCO3 (sodium bicarbonate) is calculated by dividing the molar mass by the number of replaceable hydrogen ions (equivalents) in the compound. The molar mass of NaHCO3 is ...

To calculate the moles of NaHCO3 in the sample, first find the molar mass of NaHCO3 by adding the atomic masses of sodium (Na), hydrogen (H), carbon (C), and three oxygens (O). 6. number of moles = mass of substance / molar mass Molar mass of of NaHCO3 = Na + H + C + 3O = 23 + 1 + 12 + 48 = 84 g /mol Now no. of moles …

2024年5月21日 · The reaction between benzoic acid and NaHCO3 produces sodium benzoate, carbon dioxide, and water. The equation is: C6H5COOH + NaHCO3 -> C6H5COONa + CO2 + H2O.

2024年5月21日 · NaHCO3, more commonly called sodium bicarbonate, has a boiling point of 1,564 degrees Fahrenheit or 851 degrees Celsius. The freezing point of sodium bicarbonate is 270 degrees Fahrenheit.

A sample that may contain NaOH, Na2CO3, and NaHCO3, alone or in a compatible combination, is titrated by the two-indicator method. A 0.8040-g sample requires 14.45 mL of a 0.1050 M HCl to reach the phenolphthalein end point and an additional 26.65 mL to reach the methyl orange end point. (FW: NaOH = 40.00; Na2CO3 = 105.99; NaHCO3 = 84.01). 25.
