Answer:
81% Yield
Explanation:
2CO + O₂ => 2CO₂
Excess 3.70g O₂ => 8.25g CO₂ (actural yield)
(3.70g O₂)/(32g O₂/mol O₂)
= 0.1156 mol O₂ => 2(0.1156) mol CO₂
= 10.175g (Theoretical Yield)
%Yield = (Actual Yield / Theoretical Yield)100%
= (8.25g/10.175g)100% = 81% Yield
Sodium Phosphide has a formula of Na3P . In order to bond ionically the charges must be equal and opposite. It will take one -3 phosphide ion to balance three +1 sodium ions forming a magnesium phosphide molecule of Na3P
The combined-gas law relates which temperature, pressure and volume.
Temperature=T
Pressure=P
Volume=V
<span>(P₁*V₁) / T₁=(P₂*V₂) / T₂
D. Temperature, pressuere and volume.</span>
This is a decomposition reaction, where ammonium nitrate is heated and decomposed to gaseous water and dinitrogen oxide.
Formulas for reactants and products with states are as follows;
ammonium nitrate - NH₄NO₃ (s)
water - H₂O (g)
dinitrogen oxide - N₂O (g)
balanced reactions when the masses of both sides of the equation must be balanced
Balanced chemical equation
NH₄NO₃(s) ---> 2H₂O(g) + N₂O(g)
Answer:
It is the way of cleaning of impurities present in metals
