What are the four Hume-Rothery rules for the solid solubility of one element in another?
If a solute differs in its atomic size by more than about 15% from the host, then it is likely to have a low solubility in that metal. The size factor is said to be unfavourable.If a solute has a large difference in electronegativity (or electropositivity) when compared with the host, then it is more likely to form a compound. Its solibility in the host would therefore be limited.A metal with a lower valency is more likely to dissolve in one which has a higher valency, than vice versa.
What should the temperature be for an alka-seltzer tablet dissolve and react?
The Temperature should be at least 40 degree Fahrenheit of higher for it to dissolve any temperature lower will take a long time to react or it will not react at all. The higher the temperature, the faster the dissolving and reacting.
Why is nitrous oxide called nitrous oxide?
Because here nitrogen has a lower valency of 1
Do gases dissolve better at a higher temperature?
More gas dissolves into the liquid.
Why aniline dissolve in alcohol but not dissolve in water?
Lower aliphatic amines are soluble in water because they can form hydrogen bonds withwater molecules. However, solubility decreases with increase in molar mass of amines due to increase in size of the hydrophobic alkyl part. So higher amines are essentially insolube in water.

Does solid dissolves more quickly in wter of higher temperature than lower temperature?
Solids dissolve in water of a higher or lower temperature depending on what the solid actually is.
An insurance policy with a higher premium most likely has?
a lower deductible

What is the role of pH in tooth decay?
PH levels indicate how acidic or basic a substance is. A pH lower than 7 is acidic and higher than 7 is basic. Since acids dissolve tooth enamel, I would say that substance with lower pHs are more likely to lead to tooth decay.
Downs and Lyons said judges did what to less attractive defendants?
If a person was deemed to have a higher level of attractiveness then they were more likely to get lower fines by Texas judges, so if people were believed to have a lower level of attractiveness they were more likely to get higher fines.

Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.

Electrons flow from areas of higher to lower voltage or from areas of lower to higher voltage?
Electronsflow from areas of lower to higher voltage, while Current flow from areas higher to lower voltage.
What does a bladderwort plant ooze to dissolve bugs?
Digestive enzymes are the oozings that bladderwort plants use to dissolve bugs. The carnivorous plants in question (Utricaria spp) employ aminopeptidase and phosphatase in higher or lower levels with higher or lower pH readings according to ecosystems and to species. For example, trap fluid pH may range from an acidic 4.1 to an alkaline 7.3, and phosphatase tends to predominate among European species.
