Answer:
a supply of electric charges which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.

From what I know personally from learning about this type of subject in the past is that children are more susceptible to the effects of toxic substances more than adults are, certain scientific data specifically indicate that children actually are for all intents and purposes more basically susceptible to toxic exposure than adults because they for the most part have proportionally definitely more intake of food contaminants, basically active developmental processes, basically multiple exposure pathways and really susceptible kind of socio-behavioral activities in a particularly major way.
Fission reactions can get out of control without neutron moderation. The correct option among all the options that are given in the question is the fourth option or option "D". The other options in this question can be discarded. I hope that this is the answer that you were looking for and it has come to your help.
Answer:
See explanation
Explanation:
9g of water contains : 9g/18 g/mol = 0.5 mole of water
1) 2 moles of hydrogen yields 2 moles of water
x moles of hydrogen yields 0.5 moles of water
x= 2 × 0.5/2 = 0.5 moles of hydrogen
Mass of hydrogen = 0.5 moles × 2 = 1 g of hydrogen
2) Number of moles of Al(OH)3 = 468 g/ 78 g/mol = 6 moles
2 moles of Al(OH)3 yields 3 moles of H2O
6 moles of Al(OH)3 yields 6 × 3/2 = 9 moles of H20
Mass of water =9 moles × 18 g/mol = 162 g of water
3) There are 13 oxygen atoms in the compound.
Mass of each oxygen atom = 16 g
Total mass of oxygen atoms = 13 × 16 = 208 g
Explanation:
Different atoms binds their outermost shell electrons with different amount of energy.
The amount of energy required to remove an electron from an atom is the ionization energy.
- Ionization energy measures the readiness of an atom to lose electrons.
- From the given problem, we can infer that in group O the ionization energy decreases down the group.
- Helium has the highest ionization energy.
- Down a group on the periodic table, ionization energy decrease because:
- atomic radii increases down the group.
- there is an increasing shielding/screening effect of inner shell electrons on the outermost shell electrons.
