Calculate the vapor pressure of an aqueous solution that contain 5g of a solute in 100g water at 25oC, know that the vapor pressure of pure water at this temperature is 23.76 mmHg and the molecular weight of the solute is 62.5 g. a) 23.4 mmHg b) 0.34 mmHg c) 22.6 mmHg d) 19.0 mmHg

introduction of a drug directly into the respiratory tract is a form of inhalation administration.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
