Describe all evidence indications that a chemical change occurred in this experiment 1. When the vinegar was added to the baking soda‚ the reaction let out a smell and it started bubbling and gas came out. The reaction also rose‚ and changed its color 2. Evaluating Conclusions. Was the law of conservation of mass really violated in Part 1 as it

Atchara Atchara is an appetizer made from pickled green papaya. Julienned or grated green papaya are placed in airtight containers and soaked for a week in cooked vinegar and sugar mixture with onions‚ garlic‚ ginger‚ pepper corn‚ and red bell pepper. This is probably the most famous appetizer in the Philippines because every region seems to have their own version. This sweet and sour tasting appetizer is usually served with fried dishes such as fried tapa‚ longganisa‚ tocino‚ and even lechon

Observations and Chemical Changes By: Andre the Giant Higgson 02/19/14 CHE 107 E1 Intro to Chemistry 1 Objective Certain Chemicals like Bromthymol blue and Phenolphthalein can be added to other chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved

If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

write down our hypothesis for what we think the mass/volume would be and so on. On the first day‚ Friday‚ in the lab we took a graduated cylinder and filled it with 250ml of vinegar before pouring it into a beaker with an egg inside of it and covering it with saran wrap to let it sit out for two days. On Monday we drained the vinegar from the beaker‚ leaving the egg in it‚ and measured how much was not soaked into the egg. We recorded the results along with our observations. Then we rinsed off the egg

The researchers will also add vinegar and salt to the mixture of the cherries. The vinegar and salt will clarify and deepen the color of the ink as well as preserve the mixture from spoiling. The equipment that will be used by the researchers is within their financial capability and it can be completed within
