Answer:
= 97.44 Liters at S.T.P
Explanation:
The reaction between Iron (iii) oxide and Carbon monoxide is given by the equation;
Fe2O3(s)+ 3CO(g) → 3CO2(g) + 2Fe(s)
From the reaction when the reactants react, 2 moles of Fe and 3 moles of CO2 are produced.
Therefore; Mole ratio of Iron : Carbon dioxide is 2:3
Thus; Moles of Carbon dioxide = (2.9/2)×3
= 4.35 moles
But; 1 mole of CO2 at s.t.p occupies 22.4 liters
Therefore;
Mass of CO2 = 22.4 × 4.35 Moles
= 97.44 L
Answer:
60 moles of NaF
Explanation:
The balanced equation for the reaction is given below:
Al(NO3)3 + 3NaF —> 3NaNO3 + AlF3
From the balanced equation above,
3 moles of NaF reacted to produce 1 mole of AlF3.
Therefore, Xmol of NaF will react to produce 20 moles of AlF3 i.e
Xmol of NaF = 3 x 20
Xmol of NaF = 60 moles
Therefore, 60 moles of NaF are required to produce 20 moles of AlF3.
There are a number of properties that both sugar and salt share. First would be that both compounds exist as solid at standard temperature and pressure. Being in a solid form, they also have crystalline structures, colorless and are odorless. Also, from research, both has certain degree of antimicrobial properties as they are being used for preservation of food products and for treating of wounds and illnesses. Another would be that both are being used as flavor enhancers in cooking. Due to their applicability, these compounds are the two of the major production industries in many countries across the globe.
You didn't give options but seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds so for example ferns and horsetails
