Answer:

A variable or alteration to one part that affects an entire system

Explanation:

  • Change in literal sense means the occurrence of some alteration or difference in a given object/situation/person etc.
  • When we talk about physical and natural systems, then one can say that if a system shifts from one state to another then it has changed.
  • The shift in the state means an alteration in its physical or chemical properties that occur in such a way that it causes a difference between the original state of the system to the final state.
  • For example, if in a human body which is a natural system if the blood pressure drops then we can say that there is a change that took place.

If 42.8 mL of 0.204 M HCl solution is needed to neutralize a solution of Ca(OH)2, how many grams of Ca(OH)2 must be in the solut
Aneli [31]

Hey There!

At neutralisation moles of H⁺ from HCl  = moles of OH⁻ from Ca(OH)2  so :

0.204 * 42.8 / 1000  => 0.0087312 moles

Moles of Ca(OH)2 :

2 HCl + Ca(OH)2 = CaCl2 + 2 H2O

0.0087312 / 2 => 0.0043656 moles (  since each Ca(OH)2 ives 2 OH⁻ ions )

Therefore:

Molar mass Ca(OH)2 = 74.1 g/mol

mass = moles of Ca(OH)2 * molar mass

mass =  0.0043656 * 74.1

mass = 0.32 g of Ca(OH)2


Hope that helps!
