What are the steps for the use of a graduated cylinder?
First, to insure greatest accuracy, one should make sure conditions are appropriate for the use of the cylinder, meaning that most graduated cylinders are calibrated for use with water at 20 degrees Celsius. One can determine this by looking for "20° TC" or "20° TD" marked on the cylinder. "TC", or "to contain", means that the volume of liquid contained in the cylinder is what is indicated by the graduated markings. "TD", or "to deliver", means the volume of liquid indicated by the markings is what will be delivered when the liquid is dispensed. This difference exists because when liquid is dispensed from any glassware a small amount remains and "TD" takes this difference into account.Second, the liquid should be poured into the cylinder carefully down one side, tilting the cylinder to minimize splashing and the formation of bubbles.Finally, to read the liquid volume, the cylinder should be on a level surface and the liquid level read at the bottom of the meniscus at eye level.
Is heterogeneous mixtures separated by filtration?
yes... Fold a piece of filter paper in half twice and shape it into a cone. Place the filter paper in the funnel. Squirt the paper cone with water so that it stays in place in the funnel. 3) Measure 25ml of milk into a graduated cylinder. Pour the milk into the funnel. Wait a few moments for the liquid to pass through. 4) Remove the used filter paper to rinse the funnel with water. Measure out 25ml of water in a graduated cylinder and pour it into a beaker. Mix 2.5ml of flour into the beaker and stir. Repeat steps 2 to 4 using this mixture instead of milk. 5) Measure out 25ml of water in a graduated cylinder and pour it into a beaker. Mix 2.5ml of pepper into the beaker and stir. Repeat steps 2 to 4 using this mixture. this is a simple way of filtering
What are five industrial or commercial processes that uses chemical reactions?
Industrial processes are procedures involving chemical or mechanical steps to aid in the manufacture of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry.
The percentage composition of a polymer used for the non-stick surfaces of cooking utensils is 24 percent C and 76 percent F by mass Explain the steps in determining the empirical formula of the polym?
C = 24/12 = 2 F = 76/19 = 4 so the composition is C2F4 which is TetraFluoroEthylene and the polymer would be PTFE - TEFLON

What are the steps involved in planning database files?
There are five steps to planning database files. These steps are collecting information, determining objects, modeling said objects, determining every object's information, and determining the relationships the objects have with one another.

Which scale is made up entirely of half steps?
The chromatic scale is made up entirely of half steps.
Half steps between scale degrees 2 and 3 5 and 6 7 and 8?
The type of scale that has half steps between those scale degrees is a harmonic minor scale.
Describe how a graduated cylinder could be used to measure the volume of a rock with an irrregular shape the process must include at least three steps?
Step 1 . calculate the volume of the cylinder step 2 . put the rock in the cylinder and fill it with water to the top step 3. measure the amount of water step 4 subtract the volume of the water from the volume of the cylinder, and you have the volume of the rock.
What are the steps to take to hone a cylinder?
There are many steps that one has to take to hone a cylinder. One must first get a machine to spin the cylinder and then one must bore into the cylinder with a cutting device.
