Hypothesis: If the following combinations of chemicals argon cockleed together, and so they will produce loosely chemical changes. Materials: -2 metal 1g spoons -calcium chloride (CaCl) -baking soda pop (NaHCO3) -phenolphthalein -bromothymol blue -plastic dish antennas -distilled water -graduated cylinder Procedure: 1. confer combinations from the ceremonial table into baggies and mix together. 2.Record observations. Observations: Legend: Amount unless otherwise qualify: Distilled water- 5ml Calcium Chloride-1g cook soda-1g Bromothymol blue (Bb) -2 drops Phenolphtholein (P)-2 drops # Combinations of Chemicals Before After 1 Distilled water, CaCl, NaHCO -fizzy -milky-coloured -bubbles -dissolved -warm 2 Distilled water, CaCl - ambiguous -did non dissolve, CaCl settled at bottom 3 Distilled water, NaHCO -dissolved -warm, and then insentient -cloudy, then clear 4 Distilled water, CaCl, NaHCO, Bb - insentient -fizzy -slightly bubbly 5 Distilled water, CaCl, NaHCO, P -same as #6 6 Distilled water, CaCl, NaHCO, P, Bb -bubbly -very cold -milk-white -opaque 7 Distilled water, CaCl(2g), NaHCO(0.

5g), Bb -loud fizzy dissension -bubbles -fizz -white -opaque 8 Distilled water, CaCl(2g), NaHCO(0.5g), Bb, P -same as #9 9 Distilled water, CaCl(2g), NaHCO(0.5g), P -fizzy -milk-white/yellow -semi-cold -opaque 10 Distilled water, CaCl(0.5), NaHCO(2g), Bb -very cold -fizzy -bubbles -white 11 Distilled water, CaCl(0.5), NaHCO(2g), Bb, P -very cold -white -opaque -more facile than bubbles 12 Distilled water, CaCl(0.5), NaHCO(2g), P -slightly cold -very bubbly -almost clings to side of bag when squeezed -white 13 Distilled water, CaCl, Bb -light blue -dissolved 14 Distilled water, CaCl, Bb, P -slightly cloudy -yellow 15 Distilled...If you need to get a full phase of the moon essay, order it on our website: Orderessay
