Answer:
B. They deliver oxygen to the blood.
Explanation:
The lungs, nose, and trachea are organs of the <u>respiratory</u> system. All three help circulate <u>oxygen</u> through the body's system. <em>*I might be wrong though* </em>
Molar mass FeTiO3 => 151.7102 g/mol
atomic mass Ti => 47.867 u
% ( atomic mass Ti / molar mass FeTiO3 ) x 100
= ( 47.867 / 151.7102) x 100
= 0.3155 x 100
= 31.55 % of Ti
hope this helps!
A. M x L = moles.
<span>b. CH3COOH + NaOH ==> CH3COONa + H2O </span>
<span>I...6 mmols....0.......7.5 mmoles </span>
<span>C... 0........0.51 mmols..0 </span>
<span>E...6-0.511 ....0.......7.5+0.511 </span>
<span>I stands for initial </span>
<span>C stands for change. </span>
<span>E stands for equilibrium. </span>
<span>Just divide mmoles by 1000 to convert to moles. I work in mmoles because I get tired of writing those zeros. </span>
<span>c. done as in b.</span>
Answer : The correct option is, (b) 
Explanation :
According to the Henry's law:

where,
= molar concentration of
= ?
= partial pressure of
= 1.0 atm
= Henry's law constant = 
Now put all the given values in the above formula, we get:


Therefore, the molar concentration of oxygen in water is,
