Oxygen cannot be broken down into a simpler substance by using chemicals :) Hope this helps and the other answer gets removed :)
Coulomb's law mathematically is:
F = kQ₁Q₂/r²
we integrate this with respect to distance to obtain the expression for energy:
E = kQ₁Q₂/r; where k is the Coulomb's constant = 9 x 10⁹; Q are the charges, r is the seperation
Charge on proton = charge on electron = 1.6 x 10⁻¹⁹ C
E = (9 x 10⁹ x 1.6 x 10⁻¹⁹ x 1.6 x 10⁻¹⁹) / (185 x 10⁻¹²)
E = 1.24 x 10⁻¹⁸ Joules per proton/electron pair
Number of pairs in one mole = 6.02 x 10²³
Energy = 6.02 x 10²³ x 1.24 x 10⁻¹⁸
= 746.5 kJ
Answer:
3290 gm
Explanation:
6.56 pints * 473.1765 ml/pint * 1.060 g/ml = 3290 gm
An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions.
<h3>What is the difference between ionic equation and net ionic equation?</h3>
- A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.
- A molecular formula has two or more atoms bonded together, whereas a chemical formula can only refer to one atom. They are both elements, and their chemical symbols are unchanged.
- An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions. It is similar to a molecular equation in that it expresses compounds as molecules.
3FeSO4(aq) + 2K3PO4(aq) = Fe3(PO4)2(s) + 3K2SO4(aq)
ionic equation : 3Fe(2+)(aq) + 3SO4(2-)(aq)+ 6Na(+)(aq) + 2PO4 (3-) (aq) → Fe3(PO4)2(s)+ 6Na(+) + 3SO4(2-)(aq)
net ionic equation: 3Fe(2+)(aq) + 2PO4 (3-)(aq) → Fe3(PO4)2(s)
K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s)
net ionic equation for K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s).
2HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2
ionic equation : CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O()
