The amount of heat needed would be the specific heat multiplied by the mass of the substance and the temperature difference. In this case, the mass would be 75.0–g, the specific heat would be 0.449 j/g °c, and the temperature difference would be <span>1535 -25= 1510
Then the calculation would be: </span>0.449 j/g °c * 75g * 1510°c = 50,849.25J
In calorie it would be: 50849.25J / 4.184J/cal= 12,153.26 calorie
Answer:
Linoleic acid has 18 carbons in its carbon chain and 2 double bonds, and the first double bond starts at the 6th carbon from the omega end, thus, it is named omega 6.
Explanation:
Fatty acids are carboxilic acids with long chains of carbon (always in even numbers). There are two types of fatty acids: saturated fatty acid s(without double bonds) or unsaturated fatty acids (with double bonds). Unsaturated fatty acids has common names (linolenic acid, palmitic acid, etc.) and the position of the first double bond present in the molecule are indicated with the greek letter omega (counting from the omega extreme, it means the one with metyl radical) . Based 0on that, unsaturated fatty acids are also called omega x, where "x" represents the position of the first double bond. In the present case, the fatty acid that has 18 carbons and two double bonds is commonly named as linoleic acid and taken into account the position of its first double bond (carbon 6) it is also called omega 6.
Based in the information given, the data that'll be affected by the error is the value of the solvent data.
It should be noted that the data that'll be affected based on the scenario given is the value of the solvent. When the preparation is kept overnight, there'll be an overflow of the solvent.
In such a case, it'll be difficult to get the correct distance that the solvent travelled. The effect on the calculated Rr is that the <em>calculated Rr</em> will be incorrect due to the error in solvent value.
