To write the electron configuration, you begin with the
normal electron configuration of the element and then add or deduct the number
of electrons that the charge designates. Rubidium will change from
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1
to
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 because it loses the last
electron.
Answer:
you did not give the specific heat like formula like it takes 1kj to raise 28grams of water by 10 grams
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, there are ways to save the forest of third world countries - this includes
1) Creating of forest reserves: Wide areas of land that are still forested can still be preserved and converted to forest reserves which can prevent these areas from being deforested as a result of human activities or industrialization.
2) Government policies: Government can put policies in place to prevent people from embarking on deforestation of certain lands. This is because some parts of the third world countries still rely on wood for cooking and other sources of daily activities.
3) Replanting of deforested areas: Replanting of trees can also help third world countries in saving the forest.
Answer:
302 kj heat is released by lowering the temperature
2HgO = 2Hg + O₂
n(HgO)=2n(O₂)=2m(O₂)/M(O₂)
m(HgO)=n(HgO)M(HgO)=2m(O₂)M(HgO)/M(O₂)
m(HgO)=2*250.0*216.59/32.00 = 3384.219 g ≈ 3 kg 384 g
