As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
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:
Explanation:
Because the image of the graduated cylinder in your question was not attached when sending it in, I have attached one which I would use to explain the answer given.
In taking readings of liquids from a measuring cylinder, you must be at eye level from the apparatus, after which you are to take reading from below the meniscus (the lower curve) of the water.
From the image I attached, that would be 24ml.
Please apply the following to your image. I hope this was helpful.
<h2>Answer:</h2>
The last statement is true. which is:
Mg is less reactive than Na because Mg has to lose one more electron than Na to complete its outermost shell.
<h3>Explanation:</h3>
Mg belongs to group II and Na belongs to group I.
Group II elements are less reactive than Group I elements. This is because it is more difficult to lose two electrons compared to losing just one electron.
