Answer:its D.
Explanation:
Energy is transformed first from chemical energy to electrical energy and then from electrical energy to light and heat energy.
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.
<span>Amino acids = 171 grams/day
Glucose = 342 grams/day
Lipid = 60 grams/day
The first thing to determine is how the concentration is being expressed. Are we using mass percent (m/m), volume percent (v/v), mass/volume percent (m/v) , or molarity (M)? In this problem we're using mass/volume.
The formula is:
%(m/v) = 100 * (grams solute)/(mL of solution)
Let's abbreviate the equation to
P = 100g/v
where
P = % (m/v)
g = grams of solute
v = volume of solution in mL.
Solving for g, we get:
P = 100g/v
Pv = 100g
Pv/100 = g
Now let's calculate the answers to the questions:
Amino acids = 950 mL of 9% solution:
9*950/100 = 8550/100 = 85.5g per feeding.
Glucose = 950 mL of 18% solution:
18*950/100 = 17100/100 = 171g per feeding.
Lipid = 300 mL of 10% solution
10*300/100 = 3000/100 = 30g per feeding.
Since the patient is being feed twice a day, double all the per feeding values. Sl
Amino acids = 85.5g * 2 = 171 grams/day
Glucose = 171g * 2 = 342 grams/day
Lipid = 30g * 2 = 60 grams/day</span>
Answer:
1. Methyl propanoate.
2. Propanol.
3. 2–pentyne
Explanation:
1. The functional group in this case is ester. We name ester by naming the group after the functional group (–COO) then followed by the parent compound with the name ending with –oate.
The group after the functional is methyl i.e —CH3.
The parent compound has 3 carbon i.e propane. The functional group replaces the –e in propane with –oate.
Therefore, the name of the compound is:
Methyl propanoate.
2. In this case the functional group is
–OH i.e alcohol.
The compound has 3 carbon i.e propane. The functional group replaces the –e in propane with –ol.
Therefore, the name of the compound is:
Propanol.
3. The triple bond represents the functional group in this case i.e alkyne. We'll give the triple bond the lowest low count by counting from the left. The triple bond is at carbon 2.
The compound has 5 carbon i.e pentyne since it contains triple.
The name of the compound is:
2–pentyne
