<span>after the 1940, the infention of : PASTEURIZATION permitted wines to be produced in places where climate was not ideal for wine production
after pasteurization process, all the microbes that exist within the wine are eliminated, which will prevent it from rottening. This make it possible to store wine for a long period of time even thought it's not in the harvesting climate</span>
Aldehyde is a group of organic compounds with the general form of RCHO. Oxidation of aldehyde can lead to the formation of the carboxylic acids, with the general form of RCO₂H.
With this oxidation, the typical reagents promoting the oxidation are chromic acids, chromate salts, permanganate, etc.
Answer:
In the 150 years since Darwin proposed the theory of evolution by natural selection, a mountain of evidence has accumulated ... How can you know what happened millions of years ago if no one was there to see it? Evidence and observation are the building blocks of all scientific inquiry; evolutionary science is no different
Explanation:
Answer:
Two reagents that can be used to distinguish between ethane and ethyne are Tollens' reagent and ammoniacal CuCl solution.
Answer: 1.09 kPa
Explanation:
Given that,
Original volume V1 = 3.2 L
Original pressure P1 = 2.8 kPa
New pressure P2 = ?
New volume V2 = 8.1 L
Since pressure and volume are given While temperature is constant, apply Boyle's law
P1V1 = P2V2
2.8 kPa x 3.2L = P2 x 8.1L
8.96 kPa L = P2 x 8.2L
P2 = 8.96 kPa L / 8.2L
P2 = 1.09 kPa
Thus, the pressure of the gas would be 1.09 kPa
