Answer:
a, d
Explanation:
a. The pressure in the container will be 42.8 mm Hg.
d. Some of the vapor initially present will condense.
The compounds that are present in both waxes and sphingomylin are FATTY ACID AND LONG CHAIN ALCOHOL.
Waxes are diverse type of organic substances which are hydrophobic in nature and they are found in both plant and animals. Sphingomyelin is a type of sphingolipid, which are found in animal cell membranes. It is especially abundant in the membranous myelin sheath which surround some nerve cells.<span />
Answer:
Explanation:
chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.
You are given
130 grams of H20 and 18 grams of H2. You are required to get the theoretical
yield of H2O. Before anything else, you should know the chemical equation of
H20 and H2. The balanced chemical reaction is 2H2 + O2 -> 2H2O. The molar
mass of H2O is 18 grams per mole and the 2 grams per mole for H2.
18g H2 (1 mol
H2/2 g H2)(2 mol H2O/ 2 mol H2)(18 g H2O/1 mol H2O) = 162 g H2O
<span>Thus the <u>theoretical
yield for 18g H2 is 162g H2O.</u></span>
<span> </span>
