Answer:
Explanation:
It involves the thinking of it as an electrical interaction between the positively charged part of an atom and the negatively charged part as well. Succinctly put, the interaction between the proton of an atom and the electron of an atom.
The relationship between these two sub atomic particles is one of the basis for many chemical bonding, and this is inclusive of all the bonds there exist. Hydrogen, Electrovalent and even Covalent bondings to mention but a few
cyanoacrylate
When cyanoacrylate polymerizes, the cyanoacrylate sticks together on an atomic level, and it becomes solid. Super Glue solidifies in all the microscopic crevices of an object that it moved into when it was a liquid, and it can form chemical bonds with any anions in the object.
Answer:
The answer to your question is: 70.7 %
Explanation:
Equation
Xe + 2F₂ ⇒ XeF₄
limiting reactant = Xe
Xe is the limiting reactant because the ratio is:
theoretical = 131/ 76 = 1.72 g
experimental ratio = 130/100 = 1.3 the amount of F increased.
131.3 g of Xe ------------------ 207 g of XeF₄
130 g of Xe ------------------- x
x = (130 x 207) / 131.3
x = 205 g of XeF₄
% yield = 145 / 205 x 100
% yield = 70.7
Answer: 0.53g
Explanation:
No of moles= volume ×molarity/1000
We have the volume and the molarity
Volume=4L
Molarity=1.7M
No of moles = 4×1.7/1000
No of moles= 0.0068moles
Remember also that
No of moles= mass given/molar mass
Molar mass of Al(OH)3
Al= 27
O=16
H=1
Molar mass = Al+(O+H)3
Molar mass= 27+(16+1)3
Molar mass= 27+(17)3
Molar mass = 27+51
Molar mass= 78g/mol
To get the mass
Mass given = no of moles × molar mass
Mass= 0.0068×78
Mass= 0.53g
4I₂+9O₂= 2I₄+2O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
