My teacher has asked me to research the amount of energy released through combustion on a natural gas stove and to show how the
Masteriza [31]

Answer:

I wouldn't be entirely sure, but I believe your teacher means the energy as in being transferred such as when you are cooking something and how it varies.  Avocado oil has a higher content of unsaturated fats. Olive oil contains a high ratio of monounsaturated fatty acids to satured fatty acids. Avocado oil has a very high smoke point, between 480°F and 520°F (270°C). The oil is a good choice for stir-fry recipes and other high-temperature cooking. It is ideal for searing meats and frying in a wok.

Olive oil’s smoke point varies depending on the processing and the grade. Light olive oil has a smoke point of 430°F, making it suitable for medium-heat frying.

Extra virgin olive oil has a low smoke point, around 220°F. It is unsuitable for high-temperature cooking or frying.

You should keep in mind that when you heat oil to its smoking point, it loses its nutrient content and becomes dangerous for consumption. It leads to the formation of toxic compounds and harmful free radicals which are carcinogenic.

Explanation:

All oils are different.  The "smoke point" of the oil is how the oil is classified.  The smoke point is the temperature at which the oil begins to smoke.  It begins to burn at this point and it can be a fire hazard.  The "flash point" is the temperature at which the oil ignites.

Your welcome

in the reaction Mg (s) + 2HCl (aq) H2 (g) + MgCl2 (aq), how many moles of hydrogen gas will e produced from 75.0 milliliters of
Anna35 [415]
This question uses mole ratios. firstly, we look at how many moles of H2 are produced for every mole of HCl: from 1 Hcl, we get half a mole of H2. therefore, however many moles of HCl are present in the 0.075 L of 1.0M HCl, half that number of H2 moles will be produced. 

n=cv
  =0.0750 x 1.0
  =0.075 mol HCl
n(H2)= 0.5 x n(HCl)
         =0.0375 moles of H2

Answer:

An experiment is a research method performed within a completely controlled environment that uses groups of individuals ( subjects), one of which the factors being tested are not spplied on, an independent factor of the hypothesys ( to be tested ), for example the resilience of a group of teenagers) and a dependant factor that is applied to check how it varyes depending on the tested factor ( for example, the most challanging experience of their generation)
