Answer:
12.875
Explanation:
Balanced equation of the reaction:
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
mole of acid = mole of base
75 × 0.150 = volume of base needed × 0.3
volume of base needed = 37.5 ml
excess OH = 0.3 × 37.5 ml / 150 ml where total volume = 75 ml + 75 ml = 150 ml
excess OH = 0.075 M
pOH = - log (OH⁻) = - log (0.075 M) = 1.125
pH + pOH = 14
pH = 14 - pOH = 14 - 1.125 = 12.875
Answer:
Explanation:
In heterogeneous mixtures, two or more ingredients (or phases, regions with uniform composition and properties) intermingle, but remain physically separate. Often it is possible to separate the original ingredients by physical means, such as filtering.
Answer:
Your body can cool itself by sweating. When sweat evaporates, it lowers your temperature
Explanation:
Im gonna go based on the content of their blood. So as the generation continues, a purebred's blood has not differentiated too much and contains 98-100% of a "pure" bloodline meaning no outsiders of where this purebred originated has mixed. A hybrid is where the original bloodline is mixed with many others, so while a purebred has 99% of the original bloodline and the hybrid has 50% and he other half belongs to an entirely different line.
