Answer:
Explanation:
Reactions between ions in solutions tend to be fast because of they are close to each other and they are free to move around. In general the rate of reaction goes as aqueous ions > gases or liquids > solids.
CuSO₄·xH₂O → CuSO₄ + xH₂O
M(CuSO₄)=159.61 g/mol
M(H₂O)=18.02 g/mol
m(CuSO₄·xH₂O)=1.50 g
m(CuSO₄)=0.957 g
m(CuSO₄·xH₂O)/M(CuSO₄·xH₂O)=m(CuSO₄)/M(CuSO₄)
M(CuSO₄·xH₂O)=M(CuSO₄)+xM(H₂O)
m(CuSO₄·xH₂O)/{M(CuSO₄)+xM(H₂O)}=m(CuSO₄)/M(CuSO₄)
M(CuSO₄)+xM(H₂O)=m(CuSO₄·xH₂O)M(CuSO₄)/m(CuSO₄)
xM(H₂O)=m(CuSO₄·xH₂O)M(CuSO₄)/m(CuSO₄)-M(CuSO₄)
x=M(CuSO₄)/M(H₂O){m(CuSO₄·xH₂O)/m(CuSO₄)-1}
x=159.61/18.02*{1.50/0.957-1}=5.0
x=5
CuSO₄·5H₂O
Answer:
C6H12O6 + 6O2 + 38ADP + 38Pi => 6CO2 + 6H2O + 38ATP is the chemical equation for cellular respiration
Explanation:
Cellular respiration is the process by which cells breakdown glucose molecules to produce energy in the form of ATP molecules and release waste products such as carbon dioxide and water molecules. Cellular respiration involves a series of reaction pathways such as glycolysis, pyruvate oxidation, citric acid cycle and the oxidative phosphorylation pathway.
The first step of glycolysis breaks down a glucose molecule to release two pyruvate molecules.
In pyruvate oxidation, two molecules of pyruvate are oxidized to acetyl-CoA molecules.
In the citric acid cycle, the acetyl-CoA molecules are used to produce the electron carriers NADH and FADH2.
In the oxidative phosphorylation pathway, NADH and FADH2 donate their electrons to oxygen and ATP molecules are produced using the energy of electron transfer and proton-pumping.
The overall equation for cellular respiration is given as:
C6H12O6 + 6O2 + 38ADP + 38Pi => 6CO2 + 6H2O + 38ATP
Kepler did not study the speed of the planets, rather, he studied how the planets move in the solar system. He proposed three laws. As a summary, he described that the planets move around the sun in the shape of an ellipse (orbit), and the Sun being one of the foci. Then, he proposed the period for the planet to complete one revolution around the Sun.
On the other hand, Newton studied the forces acting on the planet (or any object in space) that explain how the planets move around the solar system as described by Kepler. Also, Kepler's observations only apply to planets and not the moons or satellites. Thus, Kepler only made laws from observations, while Newton based it from underlying principles that led him to mathematical equations such as the law of universal gravitation.
