Answer:
74.1%
Explanation:
Based on the reaction:
S₈ + 16F₂ → 8SF₄
<em>1 mole of sulfur reacts with 16 moles of F₂ to produce 8 moles of SF₄</em>
<em />
To solve this question we must find the moles of each reactant in order to find the moles of SF₄. Thus, we can find the theoretical mass produced. Percent yield is:
Percent yield = Actual yield (25.0g) / Theoretical yield * 100
<em>Moles S₈: 256.52g/mol</em>
10.0g * (1mol / 256.52g) = 0.0390 moles
<em>Moles F₂:</em>
<em>PV = nRT</em>
PV/RT = n
<em>Where P is pressure in atm, V is volume in liters, R is gas constant and T is absolute temperature (0°C = 273.15K)</em>
2.69atm*5.00L / 0.082atmL/molK*273.15K = n
0.600 moles = n
For a complete reaction of 0.600 moles F₂ are required:
0.600mol F₂ * (1mol S₈ / 8 mol F₂) = 0.075 moles S₈
As there are just 0.0390 moles, S₈ is limiting reactant.
The theoretical moles and mass of SF₄ -Molar mass: 108.07g/mol- is:
0.0390 moles S₈ * (8mol SF₄ / 1mol S₈) = 0.312 moles SF₄ * (108.07g) =
33.7g
Percent yield = 25.0g / 33.7g * 100
= 74.1%
In a reaction, molecular entity that is formed from the reactants. For example, consider this hypothetical stepwise reaction: A + B → C + D.
Mitochondria is the site of ATP synthesis in eukaryotic cell during aerobic respiration. It regulates the biochemical processes of the cell and helps in generation of co enzymes as sulphur and iron.
Explanation:
Mitochondria is a cell membrane bound organelles present in cytoplasm of eukaryotic cells.
The major roles of mitochondria in eukaryotic cell is to synthesize ATP by cellular respiration. It also regulates the metabolism or biochemical processes of the cell.
Mitochondria also aids in generating the iron and sulphur which acts as a coenzyme in several biochemical reactions.
The electron transport chain takes place in inner mitochondrial membrane.
There are 2 aerobic phases of cellular respiration those are Kreb's cycle and electron transport chain. The machinery for Kreb's Cycle is in matrix. The ETC is present as embedded in the inner membrane of matrix.
The cellular compartment of mitochondria performs following functions:
The space in intermembrane has electron transport chain and holds ATP synthase (enzyme required for
The cristae is a finger like projection which increases surface area for increase ATP synthesis.
In matrix of the mitochondria the Electron transport takes place.
In Kreb's cycle mitochondria aids in production of NADH and GTP. Also, synthesis of phospholipid takes place in mitochondria.
Answer:
there are several types of Kinetic Energy: radiant, thermal, sound, electrical and mechanical.
Explanation:
Radiant energy is energy that travels in waves Its given off by electromagnetic radiation
Thermal energy results in an object or a system having a temperature that can be measured but it has to have motion
Sound a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid
Electrical When you let go of that ball and let it fall, the potential energy converts into kinetic energy
Mechanical is the result of its motion
