The error in the student's reasoning happened as they get confused between the beta minus decay and beta plus decay.
<h3>What is beta minus decay?</h3>
A neutron is converted into a proton in beta minus, increasing the atomic number of the atom.
- The proton is positive, while the neutron is neutral.
- The nucleus also produces an electron and an antineutrino in order to ensure charge conservation.
In the given question beta minus decay is not occur as atomic number of the daughter nuclei does not increases. Rather than this in the given decay atomic mass of the daughter nuclei is less than the parent nuclei means plus beta decay is happened there.
Hence the error is in predicting the correct particle with charge.

The atomic number shows the number of protons and the number of protons is equal to the number of electrons. Therefore there are 45 electrons present.
the balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ --> 2NH₃
stoichiometry of H₂ to NH₃ is 3:2
in gases number of moles of gas is directly proportional to volume of gases.
therefore molar ratio is equal to volume ratios.
this means volume ratio of H₂ to NH₃ is 3:2
volume of H₂ reacted - 54.1 L
if 3 L of H₂ forms - 2 L of NH₃
then 54.1 L of H₂ forms - 2/3 x 54.1 = 36.1 L of NH₃
volume of NH₃ formed is 36.1 L
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
When a block of ice is placed in a frying pan, it is first in a solid state, meaning that the particles are moving slowly and are tightly compacted together as well as vibrating. As the the temperature of the pan increases, the state of matter will go from a solid to a liquid, which will cause the thermal energy in the ice cube to increase and the particles will go from a vibrating state, to sliding state. By this time the ice will now be water. As the temperature of the pan continues to increase, the water will eventually become water vapor and turn into a gas because as the particles are heated, they will move faster causing them to expand.
