Answer:
They are most likely associated with the "Promotion" marketing mix element.
Explanation:
The marketing mix is made up of 7 elements which are:
-Product
-Price
-Promotion
-Place
-Packaging
-Positioning
-People
Promotion
Promotion essentially includes all the methods,ways and means you inform your customers about your product or services and how one can market the products and make sales from them.Apple's "creative pros" and "evangelists" basically promote Apple products by their activities since they make the customers know more about what Apple products can do thereby getting support for the Apple product which serves as a form of publicity for the products and as the publicity increases it would increase the sales of Apple products.Just as advertising serves to increase sales.
Supersaturated is the correct answer
Answer: molecular formula = C12H16O8
Explanation:
NB Mm CO2= 44g/mol
Mm H2O= 18g/mol
Moles of CO2 = 36.86/44=0.84mol
0.84mole of CO2 has 0.84 mol of C
Moles of H2O = 10.06/18= 0.56mol
1mol of H20 contains 1mol of O and 2 mol H,
Hence there are 0.56mol O and (0.56×2)mol H
Hence the compound contains
C= 0.84 mol H= 1.12mol O=0.56mol
Divide through by smallest number
C= 0.83/0.56= 1.5mol
H= 1.12/0.55= 2mol
O= 0.56/0.56= 1mol
Multiply all by 2 to have whole number of moles = 3:4:2
Hence empirical formula= C3H4O2
(C3H4O2)n = 288.38
[(12×3) + 4+(16×2)]n= 288.38
72n=288.38
n= 4
:. Molecular formula=(C3H4O2)4= C12H16O8
Answer:
Alkali metals
Explanation:
The alkali metals are a group of metallic elements which are present in the first group of the periodic table. In other words, they are present in group 1 of the periodic table. These elements have one electron in their valence shell, the reason why they are placed in group 1.
They ionize by losing one electron to achieve the configuration of the nearest Noble gas or inert gas. Because they need to offset only one electron in their outermost shell, they are very chemically reactive and hence rarely occur in the free state.
Examples of elements in this group include lithium, potassium and sodium. They each have one electron only in their outermost shells.
