pH of the Sr(OH)₂ solution : 12.6
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
Sr (OH) ₂ solution is a base with valence 2, so we determine the pOH from the OH ion concentration - which is expressed by pOH = - log [OH -]. After that we determine the pH value from the relationship:
[H⁺] [OH⁻] = Kw=10⁻¹⁴
pH + pOH = 14
Sr(OH)₂⇒Sr²⁺+2OH⁻
From equation [Sr(OH)₂] : [OH⁻]=1 : 2, so [OH⁻]=
Answer:
when a tire is underinflated, more of its surface area comes in contact with the road. This can cause your car to feel sluggish and slow to respond, and may decrease your fuel economy. ... Pro-Tip: Don't count on your electronic tire pressure monitoring system Explanation:
The Reactants and the Product
Answer:
Altitude is related to air pressure. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude.
Explanation:
Pretty sure it's a pressure wave
