The main contaminant we will focus on is grease or oil which is common in machines as a lubricant. The group will focus on using Sodium Bicarbonate or Baking Soda and Oyster. Both of these materials have proven to be effective stain removers with vinegar being 8% acetic acid diluted in water. The group plans on mixing the two ingredients to create a cleaning agent capable of removing grease or oil stains. It will be used for stains found in cloth. Sodium Bicarbonate is also used as a deodorant and

Over the years they start trading with animals‚ drinking alcohol‚ sleeping in beds‚ making animals enemies and killing animals. Napoleon also becomes an egomaniac and has a food taster‚ has dogs to guard him at all times‚ gun is fired on his birthday‚ etc. this just goes on to show how he is becoming more like a human. Later on the remaining pigs also took up whips‚ walked on hind legs‚ started to wear clothes and played cards.

First is the Maki sushi. Maki sushi is made with sushi rice with vinegar‚ also known as shari‚ with vegetables and a long slice of fish. To start off with‚ get a piece of nori sheet. Feel the nori sheet on both sides and you will find one side to be smooth and the other a little rougher. A Nori is a piece of dried or toasted

experiment is to see how the contaminants will affect the ground water. III. Body Paragraph #3 – Hypotheses~ a. Oil hypothesis = I hypothesize that the oil with settling on top of the water. b. Vinegar hypothesis = I hypothesize that water will not change in color‚ but it will smell like vinegar. c. Laundry detergent hypothesis = I hypothesize that the detergent will make the water smell good and change colors. I hypothesize that carbon is the best filtration technique to remove contaminants

The purpose of “manglue” is to use extracts of mango as an alternative ingredient to the vinegar ingredient of glue. The vinegar ingredient of the glue that makes the odd will be replaced with an extract from a mango‚ so that the scent of the glue will be pleasant‚ will have a touch of a different color and will be cheaper than the commercial glue.

(Although‚ we only need four eggs extras are made in the case some of them break.) The bowl is drained after 1.5 days and new vinegar is added until the eggs are covered. The vinegar is drained 1.5 days after replacing the vinegar. Each egg is rinsed in tap water. The eggs are now decalcified and the plasma membrane is exposed. Next‚ prepare our solutions of
