<span>The chemical properties of elements is determined by the electron shell configurations of each element. Different electron shell configuration = different chemical properties. And the number of electrons that an element has is determined by the number of protons the element has in it's nucleus. Iron has 26 protons, so a neutral atom of iron will have 26 electrons, while nickle has 28 protons, therefore when neutral will have 28 electrons. And since they have differing numbers of electrons, their electron shells differ and therefore their chemical properties differ.</span>
Answer:
The mass of nitrogen molecule 
= 45.65 g
Explanation:
The equation for the redox reaction can be represented as follows:
We know that:
numbers of moles = mass/molar mass
For 
:
number of moles = 50g/92 g/mol
number of moles = 0.5435 mol
For 
:
number of moles = 45 g/ 32 g/mol
number of moles = 1.40625 mol
From the above equation;
number of moles of needed = 1/2 moles of = 1/2 × 1.40625 mol
= 0.703125 mol
The amount of present = 0.5435 moles which is less than the needed. As such is the limiting reagent
The number of moles of nitrogen molecule produced = 3 × ()
= 3 × 0.5435
= 1.6305 mol
The mass of nitrogen molecule = number of moles of × molar mass of
The mass of nitrogen molecule = 1.6305 mol × 28 g/mol
The mass of nitrogen molecule = 45.654 g
The mass of nitrogen molecule = 45.65 g
Answer:
Aluminium
Explanation:
Aluminium is the only atom that has 13 electron
KOH + H2SO4 —> K(+) + HSO4(-) + H2O
Or a total reaction
2 KOH + H2SO4 —> 2 K(+) + SO4(2-) + 2 H2O
Answer: Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)
