What is the pH of a solution

A measure of the acidity of a solution

What is the nuclear decay equation for an example of alpha decay

The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He

where 24He represents the alpha particle, which is a Helium nucleus.

What describes the behavior of an ideal gas

The ideal gas law, which is a good approximation to the behavior of many gases under many conditions, even though it has many limitations. It is a combination of Boyle's law and Charles's law and was first stated by Emile Clapeyron in 1834.

Why does increasing the temperature make a solid dissolve faster

The solvent molecules bump into the solid more often.
