Answer:
1 mole FeCr2/ 1 mole FeCr2O4
Explanation:
We have to write down the equation of the reaction before we can answer the question;
2C(s) + FeCr2O4(s) -------> FeCr2(s) + 2CO2(g)
By inspection of this reaction equation, we can clearly see that the mole ratio of the reactants and products is 2:1:1:2.
Specifically, the ratio of chromites to ferrochrome is 1:1
Hence;
The mole ration required to convert chromites to ferrochrome is;
1 mole FeCr2/ 1 mole FeCr2O4
Answer:
Molar mass = 0.09 × 10⁴ g/mol
Explanation:
Given data:
Mass = 0.582 g
Volume = 21.3 mL
Temperature = 100°C
Pressure = 754 mmHg
Molar mass = ?
Solution:
(21.3 /1000 = 0.0213 L)
(100+273= 373 K)
(754/760 = 0.99 atm)
PV = nRT
n = PV/RT
n = 0.99 atm × 0.0213 L / 0.0821 atm. L. mol⁻¹. k⁻¹ × 373 K
n =0.02 mol/ 30.6
n = 6.5 × 10⁻⁴ mol
Molar mass = Mass/ number of moles
Molar mass = 0.582 g / 6.5 × 10⁻⁴ mol
Molar mass = 0.09 × 10⁴ g/mol
Answer: energy is transferred, but it can go to the products or the reactants.
Explanation: in a chemical reaction, the atoms and molecules that interact with each other are called reactants.
There is no picture so I can't say the answer please update your post with the image BECUASE all non metals are located in the same group in the periodic table
