True. The d block shells are always n-1. f shells (lanthanides and actinides) are n-2 shell number.
Answer:
halides
Explanation:
This is one electron away from having a full octet of eight electrons, so these elements tend to form anions having -1 charges, known as halides: fluoride, F-; chloride, Cl-, bromide, Br-, and iodide, I-. In combination with other nonmetals, the halogens form compounds through covalent bonding.
These types of animals are referred to as D. scavengers.
Scavenger animals are adapted to feed on dead and decaying meat and usually feed on the carcasses left over by predatory animals. An example is how vultures pick off the meat from a zebra carcass that has been left over after a lion pack has finished eating from it.
<span>A)How many moles of O2 are required for the complete combustion of 2.2 g of C3H8 to form CO2 and H2O?
C3H8 + 5O2 = 3CO2 + 4H2O
2.2 g C3H8 ( 1 mol / 44.11 mol ) ( 5 mol O2 / 1 mol C3H8) = 0.25 mol O2
b)A 65.25 g sample of CuSO4•5H2O (M = 249.7) is dissolved in enough water to make 0.800 L of solution. What volume of this solution must be diluted with water to make 1.00 L of 0.100 M CuSO4?
M1V1 = M2V2
[65.25 ( 1 / 249.7 )/ 0.800 L] (V1)= 0.100 (1.00 L)
V1 = 0.31 L or 310 mL </span>
