Phosphorylation is a process in which addition of phosphoryl group is added. This process explains the presence of the PO₃⁻ in the molecules. One type of phosphorylation is that which is termed as the substrate-level phosphorylation. This is a metabolic reaction that allows or results to the formation of ATP due to the direct transfer of phosphoryl to ADP.
Hence, the answer is ATP.
Answer:
Explanation:
Look up the density of the material the object is made of in kg/m³.
Measure the volume of the object in m³.
Multiply the density by the volume.
You will then have the mass of the object in kg.
<u>Answer:</u> The mass of potassium superoxide required is 142.2 grams
<u>Explanation:</u>
The chemical equation for the reaction of potassium superoxide with water follows:

Number of moles of potassium superoxide reacted = 2 moles for given amount of heat released
To calculate the mass for given number of moles, we use the equation:

Molar mass of potassium superoxide = 71.1 g/mol
Moles of potassium superoxide = 2 moles
Putting values in above equation, we get:

Hence, the mass of potassium superoxide required is 142.2 grams
