There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.
<h3>What is the mass of a substance?</h3>
The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.
To determine the energy from the 8g of carbohydrate, we have:
= 8g × 4 kcal/g (the corresponding calories of food type)
= 32 kcal
The energy from 2g of fat = 2g × 9 kcal/g
= 18 kcal
The energy from protein is calculated as:
= 140 kcal - 32 kcal - 18 kcal
= 90 kcal
The required mass of the protein in grams is:
= 22.5 grams
Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.

Answer:
D. Oxidation
Explanation:
In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.
A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).
Answer:
Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. Wikipedia
Formula: C10H16N5O13P3
Molar mass: 507.18 g/mol
IUPAC ID: [[(2R,3S,4R,5R)-5-(6-aminopurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy-hydroxyphosphoryl] phosphono hydrogen phosphate
Acidity (pKa): 6.5
Soluble in: Water
UV-vis (λmax): 259 nm
Explanation:
F. None of the above [Cl^(-) is oxidized]
<em>No Cl atoms are available</em> to be oxidized, only Cl^(-)ions
2Cl^(-) → Cl_2 + 2e^(-)
The substance that <em>loses electrons</em> is oxidized.
Remember <em>OIL</em> RIG (<em>O</em>xidation<em> I</em>s <em>L</em>oss of electrons) and
<em>LEO</em> the lion says GER (<em>L</em>oss of Electrons is <em>O</em>xidation).
