For lab 4, we combined baking soda with vinegar, according to the chemical equation NaHCO 3 + CH 3COOH ==== NaCH 3COO + CO 2 + H 2O Consider 3 experiments: (i) 2g baking soda + 5mL vinegar, (ii) 2g baking soda + 10mL vinegar and (iii) 2g baking soda + 20mL vinegar. The amount of CO 2 produced was highest for (iii) and lowest for (i). For these experiments, which of the following is true? Vinegar ran out first Baking soda ran out first They both ran out at the same time Neither ran out

Which effect of the chemical industry is a positive one? O advancements in medicine. O pollution of water O acid rain O building manufacturing

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below. Volcano # 1 Volume of gas produced (mL.) vs. Time (s) for Volcano #1 Time Volume of gas (s) produced (ml) 60 E 50 10 20 30 25 8 40 38 46 30 20 Volume of gas produced (ml) 40 50 50 60 52 of 10 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas Volume of gas produced…

You are asked to prepare a 1.000 L solution of 4.5 M you commit a user error while preparing this solution. Assumed volume Volumetric error Preparation details Added water 2.0 cm above the line, which corresponds to 8.2 mL (0.0082 L) additional solution volume C6H12O6 (glucose; molar mass = 180.16 g/mol) in a lab by dissolving 811.0 g of glucose in water. Consider the following two scenarios in whic Prepared in a beaker Prepared in a volumetric flask 1.000 L You add the glucose to a volumetric flask and then add water until it dissolves. The water bottle you are using has a worn tip, and you inadvertently add too much water such that the meniscus is above the line. The diameter of the neck of the volumetric flask is 2.29 cm. 811.0 g glucose Concentration: You decide to evaluate and compare the errors you made while preparing the solutions using the different methods. Calculate the actual concentrations of the intended 4.5 M glucose solutions prepared by each method based on their…
