Answer:
100%
Explanation:
Cell is the structural and functional unit of life. Without Cell, an organism can never be created.
The weakness of the rutherford model of the atom that bohr addressed is that
- The energy of the atom is quantized and
- The atom does not lose energy as the electon rotates about the nucleus
<h3>What is Rutherford model of the atom?</h3>
The Rutherford model of the atom proposed by Ernest Rutherford in 1911 shows that the atom is much hollow space with its mass concentrated at the center being surrounded by electrons. It is the planetary model.
<h3>What is the Bohr model of the atom?</h3>
The Bohr model of the atom proposed by Neils Bohr in 1913 suggests that
- the energy of an atom is quantized and
- that it does not lose energy as the electron rotates about the nucleus.
<h3>What was the weakness of the rutherford model of the atom that bohr addressed?</h3>

Answer:
The equation for the rate of this reaction is R = [NO] + {O2}
Explanation:
The rate-determining step of a reaction is the slowest step of a chemical reaction which determines the rate (speed) at which the overall reaction would take place.
Reaction mechanism:
The slow and fast reactions both have NO3 which is cancelled out on both sides, in order to get the overall reaction.
The rate law for this reaction would be that for the rate determining step:
R = [NO] + {O2}
Answer: The mass percent is 0.064%
Explanation:
To calculate the mass percent of solute in a given solution, we use the formula:
Mass of sugar (solute) = 32 g
Mass of solvent = 50 kg = 50000 g ( 1kg=1000g)
Putting values in above equation, we get:
Hence, the mass percent is 0.064%
