Answer:
there are 4 possible isomers
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.
Answer:
ΔH > O and ΔH > TΔS
Explanation:
When a reaction is non-spontaneous even though the standard entropy change of the reaction is large and positive the reason is the reaction is highly endothermic and dominates the term TΔS in the standard Gibbs free energy expression:
ΔG = ΔH-TΔS
Remember that for an endothermic reaction to be spontaneous ΔG < 0 and this can occur only if the term TΔS is greater than ΔH. This is not the case for quartz which requires a good quantity of energy to overcome its crystaline 3D lattice in which the oxygen are shared between 2 silicon atoms.
Bismuth = Bi
cesium = Cs
bismuth + cesium = BiCs
Answer:
Like charges repel
and opposite charges attract each other
lonic bonds are formed when ions attract
each other
Explanation:
An electrical charge can be either positive or negative. Two positive charged atom can never combine as they experience strong nuclear repulsive force Like wise two negatively charged atom can never combine as they repel each others negative electrostatic field.
An ionic bond is formed between two atoms in which one is electron deficient and other has surplus electron.
The atom with surplus electron is negatively charged and the atom with deficient electron is positively charged and thus these two oppositively charged atoms attract each other
