Answer:
2522g
Explanation:
8Fe + S8 —> 8FeS
From the question,
8moles of Fe required 1mole of S8.
Therefore, Xmol of Fe will require 5.65mol of S8 i.e
Xmol of Fe = 8 x 5.65 = 45.2moles
Now we need to covert 45.2moles to gram. This is illustrated below below:
Molar Mass of Fe = 55.8g/mol
Number of mole of Fe = 45.2moles
Mass of Fe =?
Mass = number of mole x molar Mass
Mass of Fe = 45.2 x 55.8
Mass of Fe = 2522g
Therefore, 2522g of Fe is needed for the reaction.
K, ca, sc is the right answer. Take a look at table S of your chemistry reference table.
Answer:
The answer to your question is: Q = 3153600 Joules
Explanation:
Data
Q = ?
m = 48 kg
T1 = 21°C
T2 = 94°C
Cp = 900 J/g°C
Formula
Q = mCpΔT
Q = (48)(900)(94 - 21) = 3153600 Joules
If mirrors did not reflect light, then we would be able to see through it.
