Which statement Ilustrates the difference between a chemical reaction and a nuclear reaction?
pishuonlain [190]

Answer:

A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.

Explanation:

  • In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
  • Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
  • The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.

Each orbit surrounding an atom is allowed _____. only 2 electrons only 8 electrons an unlimited number of electrons a limited nu
PIT_PIT [208]

Each orbit surrounding an atom is allowed A LIMITED NUMBER OF ELECTRONS.

The number of orbit that an atom has is determined by its atomic number, the higher the atomic number the higher the number of orbit in the atom and each orbit has different energy level. Each orbit can only take fixed number of electron. The first shell can only take two electrons while the subsequent shells can only take eight electrons. When an orbit has taken the highest number of electron possible, the remaining electrons are moved to the next shell.

A solution of ammonia has a pH of 11.8. What is the concentration of OH– ions in the solution
lesya692 [45]

~~~~~\text{pH} + \text{pOH} = 14\\\\\implies \text{pOH} = 14- \text{pH}\\\\\implies \text{pOH} = 14 - 11.8\\\\\implies \text{pOH} = 2.2\\\\\text{Now,}\\\\~~~~~~~\text{pOH}= -\log\left[\text{OH}^{-1}\right]\\\\\implies \left[\text{OH}^{-1} \right] = 10^{-\text{pOH}} = 10^{-2.2}~ = 0.006309~M\\\\\text{Hence the concentration of OG}^{-1}~ \text{is 0.006309~M}
