Answer:
could you explain a bit more? I will try my best to help but I need you to explain a bit more.
Most common mineral acids solutions (HCl, H2SO4, HNO3, H3PO4, etc.) are prepared in water. Infact, system is<span> acidic only in aqueous medium.

However, in few cases, it isn't advisable/viable to perform reaction is aqueous medium. This can be due to poor solubility of reactant in water. This situation arises especially, if reactant is highly non-polar in nature.
There also exist a possibility that, reactant is not stable in aqueous medium. In such event, use of water has to be avoided.
For such reaction, solid camphorsulfonic acid is added in reaction, when acid is required to initiate/catalyst the reaction.
The major advantage that camphorsulfonic acid offers is that, it is solid and hence it is easy to weight. Also, they don't required water addition for the reaction.
Democritus's idea of matter doesn't relate atoms to a measurable property, while Dalton's theory can be tested through quantitative experimentation. Hope it helped :)
Answer:
An another result of climate change is the increasing in the frequency of high intensity rainfall events,which increase the regional water damage events.If the precipitation volume decreases in summer time and increases in winter time,then it will be lower infiltration and more runoffs.
Answer:
See below.
Step-by-step explanation:
A typical heating curve for water looks like the diagram below.
It consists of five general areas.
- Warming of ice.
- Melting of ice. At 0 °C, ice and water are at equilibrium. If the water is cooling, the process is called <em>freezing</em>.
- Warming the water.
- Boiling of water. At 100 °C, water and steam are at equilibrium. If the steam is cooling, the process is called <em>condensation</em>.
- Heating the steam.
