1) Miles Davis, a famous Jazz musician, has sickle-cell anemia. This disease
results in an abnormality on the oxygen-carrying protein, hemoglobin
which is found on red blood
cells. As a result, red blood cells become rigid
and sickle shaped. Due to this disease, Miles has developed a number of
health problems such as brittle bones, swelling of hands and feet,
breathing problems and low iron levels in the blood. As a trumpet player,
Miles Davis had to cancel several concert dates due to broken wrists and
hips. What is the underlying cause of his injuries?

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

will have a gram-molecular weight of 352g.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
