electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal).
Answer:
a) 113g Sr3(PO4)2
b) 1.5g H2
Explanation:
The number of moles of Sr used in the equation
= mass/ molar mass
=65.30/87
= 0.751mol
Since the mole ratio of Sr: Sr3(PO4)2 is 3:1
moles of Sr3(PO4)3 = 1/3*0.751
= 0.25mol
grams of Sr3(PO4)3 is = moles * molar mass
= 0.25 * 452
= 113g
b). Since mole ratio of Sr:H2 is 3:3
moles of H2 = 0.751 * 3/3 ---> 0.751 mol
grams of H2 is = moles * molar mass
= 0.751 * 2
= 1.502g
The correct answer is option C.
1-hexene is an unsaturated hydrocarbon.
2-methylheptane
, 3-ethylpentane and cyclopentane have the suffix -ane, which means they are all alkanes . Alkanes do not have any unsaturation or double bonds.
1-hexene, has the suffix -ene, which means that it is an alkene. Alkanes do have unsaturation or double bonds. As the name indicates, 1-hexene has one double bond.
CH₂=CHCH₂CH₂CH₂CH₃
