<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an atom to attract the shared pair of electrons towards itself whenever a bond is formed.
This property increases as we move from left to right across a period because the number of charge on the nucleus gets increased and electrons are attracted more towards the nucleus.
This property decreases as we move from top to bottom in a group because the electrons get add up in the new shells which make them further away from the nucleus.
Thus, the correct answer is Option A.
The formula for rubidium nitride is RbNO3.
True. For example, electron domain geometry and molecular geometry of water and ammonia are different.
Answer:
Because all farms cant afford it... im not sure if this is the answer your lookin for but if it aint lmk and ill delete my answer
Explanation:
The given balanced reaction is,
![4Fe(s) + 3O_{2}(g) --->2Fe_{2}O_{3} (s)](https://tex.z-dn.net/?f=%204Fe%28s%29%20%2B%203O_%7B2%7D%28g%29%20---%3E2Fe_%7B2%7DO_%7B3%7D%20%28s%29%20)
The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.
The mole ratios of different products and reactants will be:
![\frac{Fe}{O_{2}} = \frac{4 mol Fe}{3 mol O_{2}}](https://tex.z-dn.net/?f=%20%5Cfrac%7BFe%7D%7BO_%7B2%7D%7D%20%3D%20%5Cfrac%7B4%20mol%20Fe%7D%7B3%20mol%20O_%7B2%7D%7D%20%20%20)
![\frac{Fe}{Fe_{2}O_{3}} = \frac{4 mol Fe}{2 Fe_{2}O_{3}}](https://tex.z-dn.net/?f=%20%5Cfrac%7BFe%7D%7BFe_%7B2%7DO_%7B3%7D%7D%20%3D%20%5Cfrac%7B4%20mol%20Fe%7D%7B2%20Fe_%7B2%7DO_%7B3%7D%7D%20%20%20%20)
![\frac{O_{2}}{Fe_{2}O_{3}} =\frac{3 mol O_{2}}{2molFe_{2}O_{3}}](https://tex.z-dn.net/?f=%20%5Cfrac%7BO_%7B2%7D%7D%7BFe_%7B2%7DO_%7B3%7D%7D%20%3D%5Cfrac%7B3%20mol%20O_%7B2%7D%7D%7B2molFe_%7B2%7DO_%7B3%7D%7D%20%20%20%20%20%20)
So the mole ratio comparing iron (Fe) and oxygen gas (
) is
4 : 3
