Answer:
Molecules in food contain chemical energy that cells use to produce Adenosine triphosphate ATP. Respiration is that the method by that cell get energy within the sort of ATP. Adenosine triphosphate captures energy obtained from the breakdown of food molecules and releases it to fuel alternative cellular processes. ATP, is that the primary carrier of energy in cells. Once energy is required by the cell, it's born-again from storage molecules into ATP.
Explanation:
Mass of the cube -1 = 8.91 g
Mass of the cube-2 = 8.88 g
Volume of the cube-1 = Volume of cube-2 = V
Density of the cube-1 = D
Density of cube-2 = D'
Density directly depends upon mass of the substance and inversely depends upon volume of the substance.
Here volume of the both cubes are same but masses are different. So, in this case densities of both cubes can be compared on the basis of masses.
This difference in densities of same material can be due following possibles:
1. May be an impurity present in the one of the cubes for which they have given different values their mass.
2. Weighing may not be working well.
3. May be an air trapped inside in one of the cubes.
its atomic weight
its atomic formula
its atomic structure
Answer: Option (b) is the correct answer.
Explanation:
Atomic weight is also known as atomic mass or molar mass of an atom.
Atomic mass means the sum of total number of protons and neutrons present in an atom.
For example, atomic mass of HCl is atomic mass of hydrogen + atomic mass of chlorine.
That is, atomic mass of HCl is 1.01 g/mol + 35.453 g/mol = 36.463 g/mol
Thus, we can conclude that molar mass of any element is always equal to its atomic weight.
To calculate the volume of 20.0 g of benzene, use the formula volume = mass/density. Given that the density of benzene is 0.879 g/mL, the volume is approximately 22.75 mL when you divide 20.0 g by 0.879 g/mL.
To find the volume of 20.0 g of benzene, we need to use the density of benzene because density is defined as mass per unit volume (density = mass/volume). The formula to calculate the volume from the mass and density is volume = mass/density.
In this case, we are given:
To calculate the volume, we divide the mass by the density:
Volume = Mass / Density = 20.0 g / 0.879 g/mL
We can now perform the calculation:
Volume = 20.0 g / 0.879 g/mL ≈ 22.75 mL
Therefore, the volume of 20.0 g of benzene is approximately 22.75 mL.

Answer: The resulting mass would be 35 grams.
Explanation: Mass cannot be destroyed, there would be no need to re-measure the mass. Therefore, if we add the masses we get 35.
