Assuming that you are talking about a battery, you could use a 9V battery, 2 pencils (sharpened on both ends), a bowel, some Blu
Tack (or any other adhesive) and 2 cups. You fill the bowel with water, enough to submerge the cups, and stick the battery to the side of the bowel. You take the cups and lay them sideways in the bowel, the water should fill the cups completely, if not then add more water. Once they are filled you turn them other so that they are upside down in the bowel. Stick the 2, double end sharpened pencils to the cathode (positive) and anode (negative). Submerse the pencils in the water and quickly put the cups over the pencils, make sure that the cups are still in the water. If you have done this correctly, you should be collecting gas!
Because you filled the cups with water, and the gas is less dense, the gas will travel up to the top of the cup and will push the water out of the cup!
A sample of gas could be collected at the positive electrode by releasing a small portion of the gas near the electrode and allowing it to be drawn toward the electrode by the electrical charge. The gas can then be collected in a sealed container attached to the electrode for further analysis.

How could a sample gas be collected at the positive electrode when using electrolysis for copper?
To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
How could you separate sodium from the chlorine in the liquid salt compound?
One method to separate sodium from chlorine in a liquid salt compound like sodium chloride (table salt) is through electrolysis. When an electric current is passed through the liquid salt, the sodium ions migrate to the negative electrode (cathode) and chlorine ions migrate to the positive electrode (anode), allowing them to be collected separately.
What conclusion can you draw when an experimental sample gives both a positive starch and a positive maltose test after incubation?
The positive starch test indicates the presence of starch in the sample which could have been broken down to maltose. The positive maltose test confirms the presence of maltose. Therefore, it can be concluded that the sample initially contained starch which was subsequently broken down to maltose during incubation.
How could a sample of gas be collected at the anode during-electrolysis of copper sulfate?
A sample of gas collected at the anode during the electrolysis of copper sulfate would likely be oxygen gas (O2) due to the oxidation of water at the anode. This would be because during this process, water is split into oxygen gas and protons, with the oxygen gas being produced at the anode.
If a lavender Shield tube is collected before a light green shield tube could occur?
The lavender shield tube collects positive ions, while the light green shield tube collects negative ions. If the lavender shield tube is collected before the light green shield tube, it means that more positive ions were present in the environment than negative ions at that moment.

Could semen sample be collected during shower?
If it mixes with the water then probobly not.

Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.

I tested positive for a urine test will same sample test positive 19 days later?
Split sample drug test? It depends.If what you're asking is, "I was positive because I was doing drugs; are the drugs going to leave my sample after 19 days?" the answer is that you'll still be positive. They freeze the second part of your sample, so there's no way anything could get out of it--and the drug metabolites in the sample wouldn't leave the sample anyway.If, OTOH, you're asking "I got a false positive for grass because I was taking ibuprofen (Advil is famous for crossreacting with THC on dip-stick tests, which is one of the reasons I hate dip-stick tests); should I have the second sample tested?" go for it. If they test the second sample on GC/MS, which is the normal way for split-sample tests, it will be able to tell the difference between Advil and weed.

A sample of gas collected at the anode during the electrolysis of copper sulfate would likely be oxygen gas (O2) due to the oxidation of water at the anode. This would be because during this process, water is split into oxygen gas and protons, with the oxygen gas being produced at the anode.
Why would the endocervical component be missing?
The endocervical component may be missing in a Pap smear if the sample was not collected properly and did not include cells from the endocervix. This could result from inadequate sampling technique or the sample being taken from the wrong area of the cervix. It is important to ensure proper collection techniques to obtain a representative sample for accurate evaluation.
The male victim asked if he could go to the bathroom and urinate What should Ensign Joyner do?
If absolutely necessary, she should ensure that a urine sample is properly collected while maintaining the chain of custody.
A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9?
To test the hypothesis that the mean weight is 6.6 pounds, you could use a one-sample t-test on the sample data. The one-sample t-test will help determine if the mean weight of the sample is significantly different from 6.6 pounds based on the data collected.
Do doorsteps contain asbestos?
The materials door steps are made of do not usually contain asbestos, but they could in some cases. If you suspect asbestos is present, have a sample collected by a qualified person and analyzed by a qualified laboratory.
What is no growth in urine culture?
No growth in a urine culture means that there was no bacterial growth detected in the sample. This could indicate that there is no bacterial infection present in the urinary tract or that the sample was not collected properly. Further testing may be needed if symptoms persist.
