Answer: (D) environmental chemistry
Explanation:
Answer:
34 gram of FeO produced 8 gram of oxygen.
Explanation:
Given data:
Mass of FeO = 34 g
Mass of oxygen = ?
Solution;
Chemical equation:
2FeO → 2Fe + O₂
Number of moles of FeO:
Number of moles = mass/ molar mass
Number of moles = 34 g /71.8 g/mol
Number of moles = 0.5 mol
Now we will compare the moles of FeO with oxygen:
FeO : O₂
2 : 1
0.5 : 1/2 × 0.5 = 0.25
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.25 mol × 32 g/mol
Mass = 8 g
So 34 gram of FeO produced 8 gram of oxygen.
4I+5O2=I4O10? which would be a synthesis reaction
The lungs control your body's pH balance by releasing carbon dioxide. Carbon dioxide is a slightly acidic compound. ... Your brain constantly monitors this in order to maintain the proper pH balance in your body. The kidneys help the lungs maintain acid-base balance by excreting acids or bases into the blood.
