Answer:
[tex]2Fe +N_{2} -> 2FeN[/tex]
Explanation:
Iron is Fe, nitrogen is N. Nitrogen is diatomic, which means it occurs as a molecular pair by itself. Iron III nitride has a chemical formula of FeN because nitrogen has a charge of 3-, and iron III tells us the iron has a charge of 3+ so you just need one of each to make the charges balance and the compound neutral.
When iron reacts with nitrogen to form iron(III) nitride, the balanced chemical equation of this reaction is as follows:
2 Fe + N₂ → 2FeN
What is balanced chemical equation ?The term balanced chemical equation is defined as a chemical equation in which mass is conserved and there are equal numbers of atoms of each element on both sides of the equation.
The chemical equation must be balanced in order to obey the law of conservation of mass. When the number of different atoms of elements in the reactants side equals the number of atoms in the products side, the chemical equation is balanced.
Nitrogen is diatomic, that means it occurs as a molecular pair by itself. Iron III nitride has a chemical formula of FeN because nitrogen has a charge of 3-, and iron III tells us the iron has a charge of 3+ .
Thus, iron reacts with nitrogen to form iron(III) nitride.

How many grams of ( S ) - 1 - chloro - 4 - ethyl - 2 - methylhexane and triphenylphosphine would you need to create 4 . 1 5g of ( S ) - 1 - chloro - 4 - ethyl - 2 - methyl triphenylphosphonium assuming an 8 1 % yield for the reaction?
Answer:
Explanation:
The standard molar mass is:
For (S )-1-chloro-4-ethyl-2-methylhexane = 162.5 g/mol
For triphenylphosphine = 262 g/mol
For ( S )-1-chloro-4-ethyl-2-methyl triphenylphosphonium = 424.5 g/mol
The mass required for 81% yield = [tex]\dfrac{81}{100} \times Theoretical \ yield = 4.15 g[/tex]
Theoretical yield = [tex]\dfrac{4.15}{0.81}[/tex]
= 5.1235 g
thus, since 424.5 g yield produce from 162.5 g
∴
5.1235 g yield will produce = [tex]\dfrac{162.5}{424.5}\times 5.1235 \ g[/tex]
= 1.9613 g of alkyl halide (-chloro) required.
Also, since 424.5 g yield produce from 262 g phosphine
∴
5.1235 g yield will produce = [tex]\dfrac{262}{424.5}\times 5.1235 \ g[/tex]
= 3.1622 g of triphenylphosphine required.

Molecules in solids only vibrate in place, while the other two have moving molecules
Is this equation balanced: AgNO3 + 2 KCl -->AgCl + KNO3 Yes No
Answer:
No
Explanation:
AgNO₃ + KCl --> AgCl + KNO₃
This reaction is a precipitation reaction. AgCl is formed as a white solid due to its low solubility in water.
