Potassium Hydroxide (KOH) when added to the solution would give the highest pH
Explanation:
Bases or Alkali are associated with high pH while Acidic substances are represented by lower pH value.
In the given option
HCl- is a strong acid hence would have pH less than 7
H2SO4- also an acid with a pH less than 7
KOH- base with a pH higher than 7
H20-neutral compound with pH as 7
KOH is a very strong base and dissociates in aqueous solution to give it's corresponding metallic ion and hydroxyl ions (OH-) which are characteristic property of any base.
Newton’s first law states that motion stays the same throughout unless changed such as a football being placed on the ground and not moving it stays at rest and the football being thrown stays in motion unless changed by direction.
248.72 g/mol
CuSO4 has a molar mass of 159.62. H2O has a molar mass of 18.02, which is multiplied by 5 to reflect the 5 H2O molecules.
159.62+5(18.02)=249.72 g/mol
Answer: Francesco Redis Experiment part 1 : The maggots were not observed in setup B and setup C because the jars were covered.
part 2 : He discovered that maggots appeared on the meat in the control jar, the jar left open. No maggots appeared in the jar covered with gauze.
Pasteur Experiment
part 1:In the pastures Experiment the microorganisms come from the air.
part 2:Louis Pasteur's pasteurization experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself.
Explanation:
Driving cars gives off gases that trap heat in the atmosphere
