Answer:
Water
Explanation
there is a hard way and an easy way to do this either you fill it up with cold water and it takes longer to disolve or you use hot/room temp water and it disolves faster because the sault particles slowly break of from one another and then disolve with in the water
Answer:
The principle of uniformitarianism describes the fact that the geological processes used to occur in the past were in the same manner and with the same intensity that as they occur in the present on the planet Earth. Therefore, uniformity in the geological processes exhibit from the unknown and unobservable past to present scenario of Earth. The present is the key to the past is the slogan of the principle of uniformitarianism.
Answer:
Final temperature = 28.0 degrees C.
Explanation:
heat absorbed = mass * specific heat * rise in temperature.
The specific heat of water is 4.186 J /g/C so we have the equation
209 = 10 * 4.186 * x where x is the temperature increase
41.86x = 209
= 5 degrees C.
A- and H3O+ interact, causing A-'s concentration to drop and [HA] to rise. As a result, the [NaA]/[HA] ratio declines. Because of the base content, the buffer's pH will be more acidic. The concentration of the acid, HA, has increased while A- has decreased.
What is Acid?
Any material that when dissolved in water has an acidic taste, can alter the colour of some indicators (such as reddening blue litmus paper), can react with some metals (such as iron) to release hydrogen, can combine with bases to produce salts, and can accelerate some chemical reactions (acid catalysis). Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These chemicals contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they are in solution.

Converting to pascal
104/1000=0.104=P1
250/1000=0.25=P2
If 0.58=0.104
=0.25
Cross multiply
Solubility =[0.58*0.25]/0.104=1.39g/l
