Answer:
Number of iodine atoms = 2 × 4 = 8
Number of oxygen atoms = 2 × 9 = 18
Explanation:
Coefficient 2 is placed in front of the product tetraiodine nonaoxide:
= 
Number of iodine atom in a single molecule tetraiodine nonaoxide = 4
Number of oxygen atoms in a single molecule tetraiodine nonaoxide = 9
Coefficient 2 is placed in front of the product tetraiodine nonaoxide:
= 
Number of iodine atoms = 2 × 4 = 8
Number of oxygen atoms = 2 × 9 = 18

Answer:Percent error= 90.9%
Explanation:
Percent error or percentage error is defined as the percentage of the difference between a measured value usually from an experiment and an exact value in comparison to the exact number.
its formula is thus
Percent error = experimental value - exact or actual value /exact value x 100
=(18.9 - 9.9 /9.9 ) x 100= 9/9.9) x 100
0.909 x 100 = 90.90 = 90.9%
Answer: a
Explanation:
Industry uses only about 18% while the others use around 70-90% of water.

Answer:
The correct answer is
[CH4][H2O]/[CO][H2]3
Option 3 is correct
Explanation:
Step 1: Data given
For the equation aA + bB ⇆ cC + dD
The equilibrium constant is [C]^c * [D]^d / [A]^a*[B]^b
Step 2: Calculate the equilibrium constant Kc
CO+3H2⇌CH4+H2O
Kc = [H2O][CH4] / [CO][H2]³
The correct answer is
[CH4][H2O]/[CO][H2]3
Option 3 is correct
