Why 3B to 7B are early transition metals?
groups 3 to 7 (IUPAC -- IIIB-VIIB or IIIA-VIIA earlier systems) are called early transition metals because they form the first half of the transition series. This means, for example, that their maximum valency, expressed in their oxy-acids and salts (titanates, vanadates, chromates, and permanganates) matches their group number, that their complexes are slow to react, etc. This contrasts with the late transition metals (IUPAC groups 8 to 12) which tend to have a maximum valency of 2 or 3, and fast reacting complexes.
How is a dichotomus key used to classify organisms?
By linking organisms with common characteristics. For instance- 1a Nonliving-See2 1b Living-See3 2a Round-Ball 2b Square-Box 3a Furry-Monkey 3b Scales-Lizard Often these keys go much more in depth than this, but for an example this is accurate.
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
6b squared minus 3b divided by 3b?
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
What is the group 3b-12b elements know as?
Transition metals or d-block elements
What are the group 3b - 12b elements known as?
d-block elements or transition metals
What is 3b squared minus 3b?
3b2 - 3b = 3b(b - 1)
What does ab 2a 3b 6 equal using factoring by grouping?
so let's group and then factor ab+2a+3b+6= (ab+2a)+(3b+6)= a(b+2)+3(b+2)= (a+3)(b+2) and that is our final answer! Doctor Chuck
What is the highest common factor for 3b and 9b?
Since 3b is a factor of 9b, it is automatically the GCF.
-2b plus 7-3b equals 2?
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
How do you solve for b when a equals 3b-c?
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
What is b 3b equals 39?
If 3b = 39 thenb = 39/3b = 13.
What is 3b plus 4-4?
3b
What is 3b-8b?
3b-8b = -5
