d-block elements or transition metals
The group 3b-12b elements are known as the transition metals. They are characterized by their ability to form colorful compounds, exhibit variable oxidation states, and have high melting and boiling points. Many transition metals are used in industrial applications and play important roles in biological systems.
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.
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
Mg or Magnesium has 2 electrons in its Valence shell. If you have the right Periodic Table it should have numbers 1A, 2A,... 3B, ect listed above each column. These numbers represent the number of Electrons in the valence shell of all the elements in that Column.
When determining the rate law for the reaction 2A 3B, factors to consider include the concentrations of reactants A and B, the order of the reaction with respect to each reactant, and any catalysts or inhibitors present that may affect the reaction rate.

No, it is not.
-9/4b -10/3b =-67/6 9/4b +10/3b = 67/6 27/12b + 40/12b = 67/6 67/12b =67/6 12b = 6 b = 6/12 b=1/2
4(3b+2)
To factorise the expression (4a + 12b), first identify the greatest common factor (GCF) of the coefficients. The GCF of 4 and 12 is 4. You can then factor out 4 from the expression: [ 4(a + 3b). ] Thus, the factorised form is (4(a + 3b)).
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
To solve the equation (-3b + 5 = 12b), first, isolate the variable (b). Add (3b) to both sides to get (5 = 15b). Then, divide both sides by (15), resulting in (b = \frac{5}{15}), which simplifies to (b = \frac{1}{3}).
4(3b - 5) < -31 + 12b12b - 20 < -31 + 12b, this is not true because -20 > - 31, so that the solution for the given inequality does not exist.
12b - 5 = 15b + 5 subtract 12b from both sides 12b - 12b - 5 = 15b - 12b + 5 - 5 = 3b + 5 subtract 5 from each side - 5 - 5 = 3b + 5 - 5 - 10 = 3b divide both sides integers by 3 - 10/3 = (3/3)b - 10/3 = b ---------------------check in original equation ( change whole numbers to fractions of common denominations ) 12(-10/3) - 15/3 = 15(-10/3) + 15/3 - 120/3 - 15/3 = - 150/3 + 15/3 - 45 = - 45 checks
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
Do you mean...? 12b + 8 4(3b + 2) ============( if you meant b12, then there is no factoring possible )
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
