Mystery Mixture Lab Report

I did see occasional bubbles, which could be due to the slight chemical reaction of the two chemicals. However, it was obviously not as strong as with the salt since the salt changed

After 5 min passed the plastic container created a thin layer of ice surrounding the container.

air. This is because the water must be heated or agitated to release the gas.

The substance I would have to say was the ball formation of the pyrite and the air bubbles in the water.

On average the Alka Seltzer tablet dissolved faster in hot water in comparison to ice cold water and room temperature water. The beaker with ice cold water caused the Alka Seltzer tablet to dissolve the slowest. The three beakers containing different temperatures of water, all produced carbon dioxide bubbles; however, the beaker containing hot water produced the bubbles more rapidly.

After adding distilled water, alka-seltzer began bubbling extensively, as the two substances react and form CO2(g) and a buffer. Sodium bicarbonate also bubbled mildly, as it reacts with water to form carbonic acid, which then breaks into CO2(g).

The control variable is the amount of water mixed with the bubble solutions. With each solution they boys mixed 5 oz. of water. If they wouldn’t have used 5 oz. in both of the solutions it could affect the way the solutions form bubbles. Which is why the amount of water has to stay the same.

Just bubbles, Bubbles. Bubbles.

In the experiment we did in science class what I observed was that when the water is added to the dry ice it automatically starts to make fog and then after a few minutes it started to boil. The water started to boil and then the dry ice dissolves completely into the water. Then the only thing that you can see is the bubbles in the water.

The lower the metal is in the group the faster it will react with water. This was seen to be true for both groups one and two. In all cases the metals reacted to form Hydrogen Gas ad a solution that was alkaline. Down the group the electronegativity decreases which results in a metal element losing its valance electrons more easily and hence reacting more

Also we noticed at the top of the liquid a bluish

This happens because of the porous surface that creates a lot of bubble growth, then

The particles didn't have any type of shape at all. The particles gained much more kinetic energy, which means that they more potential energy and they were heated up even more than the previous substance. Instead of touching the bottom of the container the particles were also touching the top of the container.

Test tube 1, had 5 centimeters of distilled water and 8 centimeters of hydrogen peroxide this resulted in no bubbles present. Test tube 2, had 5 centimeters of catalase and 8 centimeters of hydrogen peroxide, 1 centimeter of bubbles were formed. Test tube 3, consisted of 7 centimeters of catalase and 8 centimeters of hydrogen peroxide, 0.5 centimeter of bubbles were formed. Although both tubes 2 and 3 reacted in bubble height, the bubbles size were different. Test tube 2’s bubbles were smaller and many more were present than test tube

Following the addition of the reagent, H2O2, many bubbles began appearing giving the appearance that the slide was fizzing, shown in Figure 6. The formation of the bubbles was due to the presence of catalase in the organism, which converts the H2O2 into water and oxygen gas, which is the indication of a positive result (Leboffe & Pierce, 2015).
