Summary:

The first test our group did was H20 + CaCl2. When we did this experiment the temperature went up, it was heterogonous, exothermic, it was dissolving, and the water turned cloudy. The next test was B.B. + CaCl2 (+H2O). This experiment turned out by the Temperature rising, exothermic, no color change, dissolved, and homogonous. The 3rd test was CaCl2 + NaHCO3 + H2O. This experiment led to Temperature rising, dissolving, fizzing, hissing sound, milky look, and heterogonous. The 4th test we did was CaCl2 + NaHCO3. It turned out by rise in temperature and warm powder. The 5th test we did was B.B. + NaHCO3. The results were temperature decrease, new smell, and color change. The 6th test was B.B. + NaCHO3 + CaCl2. The results were rise in temperature, many bubbles, hissing sound, green liquid, water level rising, and it was a colloid. The test we did as a whole class was NaHCO3 + H2O. The experiments ended up as it dissolving and drop in temperature.
