there is two mixture homogeneous and heterogeneous mixture
ok
Answer:
63.546
Explanation:
The Average atomic mass is calculated using the formula:
sum of the product of the atomic masses and their relative abundances all divided by 100 or total abundance
Answer:
Products have a lower total Gibbs free energy in comparison with the reagents total Gibbs free energy.
Explanation:
Hello,
Exergonic chemical reactions are those that the overall Gibbs free energy is negative, it means that the products have a lower total Gibbs free energy, turning out into a spontaneous chemical reaction. Such reactions are thermodynamically possible under standard conditions and they usually release heat.
Best regards.
Actually Rb or Rubidium in zero state has the following
electron configuration:
<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>
However we can see that the ion has a 1 positive charge,
which means that it lacks 1 electron, therefore the answer from the choices is:
<span>d.
rb+: 1s22s22p63s23p64s23d104p6</span>
