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.
Answer:
The molecules in liquids flow, and are able to move more than those in solids
Alpha particles can<span> only travel a few inches and beta particles around 10 feet. ... However, living tissue inside the body offers no </span>protection against<span> inhaled or ingested alpha ... Thick, dense shielding is necessary to </span>protect against<span> gamma rays. so your answer would difinetly be uranium

C is the answer
hope this helps!
