Answer:
True
Step-by-step explanation:
An ionic bond is the attraction between a cation and an anion.
If there is no cation or anion, there is no ionic bond.
Answer:
I'm not 100% sure,but I think its trigonal pyramidal
Answer:
17,932.69 g/mol is the molecular weight of the substance.
Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution = 1.04
c = concentration of solution =?
l = length of the cell = 1 cm
= molar absorptivity of this solution = 18,650 
Now put all the given values in the above formula, we get the molar absorptivity of this solution.
c = 

V = Volume of the solution in L
Molecular weight of the substance = x
V = 100 mL = 0.1 L
Mass of the substance = 100 mg = 0.1 g

x = 17,932.69 g/mol
17,932.69 g/mol is the molecular weight of the substance.
Answer:
Increase in temperature increases the average kinetic energy of the reactant molecules, hence lowering the activation energy of the reaction.
Answer:
Primer postulado:
Así Bohr asumió que el átomo de hidrógeno puede existir solo en ciertos estados discretos, los cuales son denominados estados estacionarios del átomo. En el átomo no hay emisión de radiación electromagnética mientras el electrón no cambia de órbita.
