There needs to be an equal amount of powder to liquid. So if you add one tablespoon of the clay powder then you need to add 1 tablespoon of liquid (you don 't need much powder to cover your whole face). The reason I say liquid is because there are two options when mixing the clay--apple cider vinegar or water. Apple cider vinegar has many benefits and if you are looking to read more about it then click here to go to the Bragg 's brand website (I personally love this brand and I find them very reliable). Personally, I recommend using water the first time you use this mask just to be safe.
First Professor Greenberg assign a labeled unknown acid solution, then we recorded the solution’s identity and bottle code. Next, we obtained an Erlenmeyer flask for the titration. Rinse it with DI water. Next we are to dispense from the buret at least mL of the designated acid into the flask. Record the initial and final volume readings on the buret in laboratory notebook data table.
We had to go back into our notes and see what matched to what. Materials I used. Were a petri dish, scapula, liquids, burner, C-clamp, tongs, gas to start the flame, eight different types of powders, and the most importa martial was our goggles for safety. The petri dish was used to put the powder in for testing. The scapula was used for scooping up the powders.
He claimed he was working at a bar filled with customers when the crime was committed. With all of his alibies, he was still charged with a crime he didn’t commit all because they found bite marks on the little girl’s wrist that seemed to match up with him. He was later released from prison when the true murdered was caught. Is DNA a reliable forensic tool? I feel that DNA is the only reliable forensic tool because its principles are example of real science.
“I knew it was you the whole time. The set ups, the lies, were they worth it?” The suspect is Kendra Goode and she is accused of murder and I’m going to prove it. First of all, Kendra poisoned the ice cubes, so that Felix would have no external injuries. Also she has her finger prints on Felix’s cup. My team of investigators took samples of the ice cubes, the pH for tap water is 7(neutral) and for the ice water a 9(base).
The SIM tube was first inspected for black precipitate indicating sulfur reduction and cloudiness around stab line for motility. Kovacs reagent was added in the tube a red color change in the alcohol layer. Red which also indicated is was positive for indole production. Methyl Red is used to determine if an organism is capable of performing a mixed acid fermentation. Methyl Red were added to MR test tube.
If the police can hack into everybody’s computer without a warrant, it would be the same as the police being able to search peoples houses without probable cause. Its not just people who don’t agree with the ruling. A Massachusetts court found that the FBI’s evidence was invalid due to it relying on a warrant that was did not apply to the
Case: 15-012345 Frog Murder How to be a Forensic Evidence Technician We are going to be working on case 15-012345 today with Deputy Ferriter. Someone last night broke into the school and murdered a pet frog. We are going to be dusting for fingerprints, and walking you through the steps. Step 1: Find a substrate near the area that the criminal could have touched during the crime scene. Step 2: Take a brush and twirl it gently between your hands so the static electricity can move throughout the brush, after doing that, dip the brush gently into magnetic fingerprint dust.
This lab consisted of determining whether a certain liquid was an acid or base and experimenting with the pH of various substances when either acid or base was added to them. The lab was executed by using two different types of indicators as well as a titration in the end. The first indicator used was litmus paper. Through litmus paper, it is possible to decide whether a liquid is an acid or a base. By placing one slip of red litmus paper by one slip of blue litmus paper and dropping beads of the liquid on each, determining whether the liquid was a base or an acid was possible.
1.) Gather all the instruments required. Gather all the foot powder products and tools like the microscope to help determine fungal infection that causes athlete 's foot or statistic tools to keep record of the effects of the foot powder brands in an athlete 's foot infected test subject. 2.) Make the foot powder.
This determined which set of tests that had to be done. My bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests.
The fatty acids in these are then made into fatty alcohols then undergo another process to sulfonate them into crystalline salt. Sodium Laureth Sulphate is Sodium Lauryl Sulphate that has been through a process called ethoxylation. Honestly (October 2015). Stacey Rosenberg (02/11/2014) Benzoyl Peroxide Benzoyl is part of the peroxide family, it is a chemical that has an anti-inflammatory and antibacterial effect but can cause stinging, itching, burning, dehydration and peeling of the skin. It is commonly used for hair bleaching, teeth whitening and acne treatment.
Materials The materials we will be using in our experiment are Dr.Pepper, water, sweet tea. We will use the water as our baseline. The Dr.Pepper will be used as one source of caffeine. The Sweet Tea will used as another source of caffeine. We will need cups to put each drink in.
