Answer:
Volume of the calcium hydroxide solution used is 0.0235 mL.
Explanation:
Moles of KHP =
According to reaction, 2 moles of KHP with 1 mole of calcium hydroxide , then 0.0330 moles of KHP will recat with ;
of calcium hydroxide
Molarity of the calcium hydroxide solution = 0.703 M
Volume of calcium hydroxide solution = V
Volume of the calcium hydroxide solution used is 0.0235 mL.
I think the best answer from the choices is option B. <span>Atmospheric chemists think that Earth’s first atmosphere contained no oxygen atoms. It was believed that the early atmosphere of the Earth was due to the volcanic activities which are not known to produce oxygen atoms. Therefore, chemists think that there were no atoms of oxygen.</span>
H2O and H3O+ are a pair. The conjugate base of an acid is the base that is formed when the acid has donated a hydrogen ion. The conjugate acid of a base is the acid that forms when base accepts a hydrogen ion.
