3. A fireproof safe is made of two thin metal boxes, one inside the other, with equal spacing between each pair of adjacent surfaces. Calculate the volume BETWEEN the two boxes given the following dimensions. Include units. Place this answer in the lab report #1 under Smaller box = 0.100 m x 0.120 m x 0.240 m Larger box = 0.134 m x 0.154 m x 0.274 m

Make a graph of the average mass vs. year. Make sure axes are labeled. Please please answer super fast please answer as fast as possible

How will each of the following experimental errors influence the results of your calculated densities you reported? State whether the error will tend to make your density results too large, too small or unchanged. Explain why this would occur by identifying which measurements would be affected (high or low) and how this would affect the calculated density. Use the followingIn method 2, the metal cylinder you used had a number of air bubbles on its when immersed in the water

Use the volume measured for the 90-drop data and calculate the volume (mL) for each drop of water. Set up a dimensional analysis.    30 drops = 1.5 mL  60 drops= 2.8 mL 90 drops = 4.4mL

Gm= 8.50g. Cp= 3.30 g. Mm= 7.10g 2Gc+ 1Mm+4Cp=1Sm 2. a. Is there a relationship between the mass of one s’more and the masses of the reactants used to make it? What is the relationship? b. What law have you studied in this course that might define this relationship? c. Write out the three mass to unit conversion factors. (Note: one is given above)

Please answer this question as fast as you can please and tahnk you. I will afterwards write an wonderful review on solving the question. Thank you. You determined experimentally the density of a solution in triplicate. Considering the results what is the %RSD of  results? Answer your question with the correct number of significant figures. Please enter answer as a % not in decimal form. Trial 1: 1.014 g/mL Trial 2: 0.914 g/mL Trial 3: 1.190 g/mL

Even though cement and bread are not substances, they can help you to understand these concepts: Whatever you do to volume affects mass the same way. Whatever you do to mass affects volume the same way. If you have half as much of a material, you would expect the volume of the material to also be half as much. If you have twice as much of the material, you would expect its volume to also be twice as much. Substances, which you know are always the same throughout, will follow this rule. This relationship between mass and volume will stay the same for any substance, no matter how much of that substance you can sample and measure in the classroom. Why is this principle about the relationship between mass and volume always true of substances, but not always true of mixtures?

ERROR ANALYSIS A student solving the problem based on the scenario below made an error and the answer is incorrect for percent by mass. Identify the error and solve the problem to determine the correct answer. Calculate the percent by mass of vinegar in a lab grade bottle when the mass of the vinegar in the bottle is 150.0 g and the mass of water in the bottle is 449.35 g. percentby mass = _Massofsolute Kl00 Massofsdlution pereent bymass = 150.0g Xl00 449.359 = 33.38% vinegar percent by mass

TRITT Part 3: Convert units of time. In chemistry, time is usually reported in units of seconds (s), minutes (min), and hours (hr). Use the conversion factors to change from one unit of time to another unit of time. Seconds → Minutes Seconds Hours Minutes →→→ Hours 10. Convert 35 minutes to hours 11. Convert 240 seconds to minutes 12. Convert 2.33 minutes to seconds 13. Convert 1.80 hours to seconds 60 s = 1 min 3600 s = 1 hr 60 min 1 hr LIVEWORKSHEETS
