Answer:
The claim is untrue.
Explanation:
Given the information from the question. We need to evaluate the claim.
According to the phase rule we have F= C-P+2
In this particular situation, the forms are completely allotropic .In order words, they are conjured through the same chemical composition. Thus constituents C= 1, P=4 for four phases and the number variables is 2. As a result, F= C-P+2 =1-4+2= -1. Therefore, the claim is untrue.
Answer:
The effects of supercritical CO2 (SC-CO2) on the microbiological, sensory (taste, odour, and colour), nutritional (vitamin C content), and physical (cloud, total acidity, pH, and °Brix) qualities of orange juice were studied. The CO2 treatment was performed in a 1 litre capacity double-walled reactor equipped with a magnetic stirring system. Freshly extracted orange juice was treated with supercritical CO2, pasteurised at 90°C, or left untreated. There were no significant differences in the sensory attributes and physical qualities between the CO2 treated juice and freshly extracted juice. The CO2 treated juice retained 88% of its vitamin C, while the pasteurised juice was notably different from the fresh juice and preserved only 57% of its vitamin C content. After 8 weeks of storage at 4°C, there was no microbial growth in the CO2 treated juice.
Answer:
from 10-14
Explanation:
the pH of potassium hydroxide is extremely high and is a strong base although the exact value depends on the concentration of the base in water.
Answer:
e/m for electron is 1/0 (as electron has negligible mass),
for proton is 1/1,
for neutron is 0/1, and for alpha particle is 2/4 or 1/2. (Note that charge unit for e is −1, for proton is +1, for neutron is 0, )
and for alpha particle is +2. The mass unit (amu) for e is almost 0, fro p is 1, for neutron is 1, and for alpha particles is 4.
Hope it helps you!
