This is one of the most interesting questions scientist ask why does this chemical reaction happen when you mix this stuff together . Why do baking soda and vinegar react with each other? This happens because of an acid base reaction and also because baking soda is a bicarbonate and vinegar is an acid and when you mix them together fiss start to show up . What does this have to do with my science fair project? This has to do with my science fair project because it shows how the volcanic

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

Baking Soda and Vinegar Rocket All the materials you will need are very simple house hold; scissors‚ balloon‚ vinegar‚ baking soda‚ rubber band‚ empty bottle‚ clear wrap‚ straight pin‚ marker‚ thin piece of wood‚ drinking straws‚ and duct tape. One of the first steps is to make the rocket fuel the key component in this rocket. I began with placing ¼ or 1/3 of vinegar in a normal size bottle‚ after that you will make the baking soda bomb. You take a piece of clear wrap and place a good amount of

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 1 The Effects of Ammonia and Vinegar on Radish Plants THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 2 Abstract INTRODUCTION OF GROUP Plants are one of the most complex organisms; how they grow is very complex and it is important to see how they grow to even how they die. We first had to propose a question and test it to see if it was profound enough to test. Our group decided to see how different chemical

possible market share‚ and to increase it further‚ it would have required additional price cut. So‚ the option with the firm was to expand its operation in the segment of specialty steel segment‚ which is typical mini mill product line. The alternative was to increase beam size capacity and directly challenge large integrated steel companies. Due to constraint of the rating of available rolling mill‚ it could make only small section beam. Manufacturing of medium and large section beams needed higher capacity

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0
