Carbon dioxide in high levels can cause death. One method of removing carbon dioxide from the air of enclosed compartments involves this reaction: Balance mell NaOH(s) + CO₂(g) → Na₂CO3(s) + H₂O(1) What mass of sodium hydroxide is required to remove all the carbon dioxide in the air over a 24h period, if the volume of CO₂ produced is 1.25 L/min at a temperature of 22 °C and a pressure of 101.8 kPa? Please give final answer in kg.

During the experiment, can the crucible and lid be touched with bare hands? (Choose all correct answers) No. If the crucible is still hot, a student can burn his or her hand. Yes. Gloves can be slippery, making it more dangerous to wear them in lab. Yes. They are easier to transport to the balance room and bare hands do not introduce error into the experiment. No. Dirt and oils on hands can add to the mass of the crucible.

In the following sub-questions, use your book and notes to generate an argument for each model of light. Remember, on the first day of class we discussed that argumentation requires: ● a claim (which I've given), • evidence (which you should look up in the form of data or scientific principles) and reasoning that connects the evidence to the claim (which you should generate from your understanding so far).

(Handwritten answer) Calculate range of volumes representing 0.1% tolerance of a 25.00 mL volumetric pipette assuming that 25.00 mL is the dispensed volume!

All boxes please. Answer choices: analytical technique or purpose

If I add 15mL of water to 8 grams of sugar in a volumetric flask, then swirl it to dissolve the sugar. Then add more water up to the 25 mL line, what is my total volume. I have the weight of the flask before and after as well.
