Answer:
<h3>X=-1/8=-0.125</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
x+2/4=3/8
2/4=1/2 (First, use the common factor of 2.)
x+1/2=3/8
x+1/2-1/2=3/8-1/2 (Then, subtract 1/2 from both sides.)
3/8-1/2 (Solve.)
3/8-1/2=-1/8
-1/8=-0.125
x=-1/8=-0.125
In conclusion, the final answer is x=-1/8=-0.125.
Answer:
8.1 moles
Step-by-step explanation:
Given parameters: Mass of water to be decomposed = 29.2g Unknown: Number of moles of oxygen. Solution: To solve this problem, we first write the balanced reaction equation : 2H₂O → 2H₂ + O₂ Now convert the given mass of the water to number of moles; Number of moles of water = Molar mass of water = 2(1) + 16 = 18g/mol Number of moles of water = = 16.2moles From the balanced reaction equation: 2 moles of water produced 1 mole of oxygen gas; 16.2 mole of water will produce = 8.1moles of oxygen gas
