You are going to clean up a hazardous waste site and some green goo is coming out of the groundwater well. You fill a 5-gallon bucket with the material and take it back to your lab to figure out what it is and if it is toxic to fish. The mass of the gallon container is 50 grams and the mass of the container with the slime is 20 kg. Compute the density, specific weight, specific volume, and specific gravity of the goo (all in SI units).

Titration of an Antacid (i.e., an anti-acid, in other words a base) Part A Procedure: 1. To a beaker of appropriate size add 190 mL of distilled water. Afterwards, using your 10 mL graduated cylinder, add 10 mL of 4 M HCl (hydrochloric acid) stock solution (CAUTION - STRONG ACID-CORROSIVE!) to the 190 mL of distilled water. Mix the solution well. Using a Rainin pipet, carefully pipet 10.000...

I really just need all the equations, please and thank you.
MATERIALS: cene nitric acid, HNO, 3.0M sodium hydroxide, NaOH 6.0 M sulfuric acid, H2SO4 zine metal DI water PROCEDURE: Make sure you record detailed observations after almost every step. You will also need to write the balanced chemical equations for almost every step. Make sure you answer any questions associated with a step 1. Weigh approximately 0.5 g of copper metal and record the weight. Place the copper in...

TrueGrid manufactures the world’s strongest permeable paver. It’s a 100% permeable, which is an alternative to concrete and asphalt. It is permeable solution that allows the water to permeate through the surface and be detained below. It’s able to handle high traffic and heavy loads, so it can go from your drive way all the way to your high traffic 18 wheeler parking lots and everything in between. TrueGrid helps prevent flooding because the biggest reason is there is no...
