Answer the Question according to the Color bromothymol ( blue, green or yellow)
Is it Blue, Green, or Yellow

1.What effect does carbon dioxide have on tap water ---pH -7.2 Yellow

2.pH after exhaled air is blown through a straw into

water for 5 min. pH=5.1

3.pH after a snail has lived in water for three days pH=5.8

4.pH with 2mL of bleach added to the water pH=9.4

5.pH with instant coffee added to the water pH=5.0

6.pH after an aquatic plant is grown in water for three days in bright sunlight---pH=7.7

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
