The following statements about blood are true except that .

Except for , the following statements about blood are true.

a.The viscosity is three to five times greater than water.

b The pH is slightly acidic.

c. It contains about 55% plasma.

D. It contains dissolved gases.

Except for the pH is slightly acidic, the following statements about blood are true.

Viscosity is an inherent feature of liquid compared to the inner resistance of nearby fluid films pushing through one another. All blood has a much greater viscosity than water.  Authorities regard these matters as “non-Newtonian fluids,” of which ketchup and blood are excellent illustrations.

Blood is usually slightly basic, with a typical pH scale of approximately 7.35 to 7.45. Plasma composes 55% of the whole blood volume. The albumin included in plasma restricts the blood from dropping too much water. The plasma of vertebrates also includes dissolved gases.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
