Answer: The correct is 0.5 moles.
Explanation:
11.412 x 10^23.
EXPLANATION:
5.5 oz = 155.92 g
155.92 g x (1 mol/82.2 g) = 1.8956 mol
(6.02 x 10^23) x 1.8956 = 11.412 x 10^23
Answer:
Observe odor, determine pH, determine density, determine boiling point
Explanation:
The correct procedures that would be best to use to determine whether a beaker contains only distilled water would be to observe the odor of the liquid in the beaker, determine the pH of the liquid, determine the density, and then determine the boiling point of the liquid.
<em>Water is generally odorless and has a pH of approximately 7 with a density of 1 kg/m3 and a boiling point of 100 </em>
<em>. If the liquid in the beaker ticks all these conditions, then it can be established to be only distilled water.</em>
Answer:
A NaCl: ionic (Na is metal and Cl is not metal)
B. AIC13: ionic (Al is metal and Cl is not metal)
C. C2H3N: covalent (C, H and N are nonmetals)
D. C3H60: covalent (C and H are nonmetals)
E. BaCl2: ionic (Ba is metal and Cl is not metal)
F. CaCl2: ionic (Ca is metal and Cl is nonmetal)
Explanation:
In ionic bonds, they are formed when there is a difference in electronegativity, between metals and nonmetals. In the case of covalent bonds, one or more pairs of electrons are shared between nonmetal compounds.
