The household substances that will turn blue litmus paper red are: A) bleach and D) Vinegar. This is because bleach contains acidic solutions; and vinegar contains a percentage of organic acids for example, acetic acid.
This is a short answer but because they have the same amount of protons and electrons but different amount of neutron
Answer:
He developed the concept of concentric electron energy levels
Explanation:
Before Bohr's model, Rutherford's model was proposed. This model explains most of the properties of the atom but failed to explain the stability of the atom.
As per Rutherford's model, electrons revolve around the nucleus in the orbit.
But revolving electron in their orbit around nucleus would give up energy and so gradually move towards the nucleus and therefore, eventually collapse.
Bohr's proposed that the electrons around the nucleus move orbit of fixed energy called "stationary states". Electrons in these stationary states do not radiate energy.
Therefore, proposal of concentric electron energy levels refine the atomic models.
Answer:
Explanation:
1 moles Gallium to grams = 69.723 grams
2 moles Gallium to grams = 139.446 grams
3 moles Gallium to grams = 209.169 grams
4 moles Gallium to grams = 278.892 grams
5 moles Gallium to grams = 348.615 grams
6 moles Gallium to grams = 418.338 grams
7 moles Gallium to grams = 488.061 grams
8 moles Gallium to grams = 557.784 grams
9 moles Gallium to grams = 627.507 grams
10 moles Gallium to grams = 697.23 grams
I want to say Neutrons.
Hope this helps!
