<h3>Answer:</h3>
3.2 moles of Oxygen
<h3>Explanation:</h3>
Acetic Acid having chemical formula C₂H₄O₂ and structural formula attached below is the second member of carboxylic family in organic compounds. It is commonly used as vinegar<em> i.e</em>. a mixture containing 5 % Acetic acid and 95 % water.
As shown in structure 1 mole of Acetic acid contains 2 moles of Carbon atoms, 4 moles of Hydrogen atoms and 2 moles of Oxygen atoms respectively. Hence, the number of moles of Oxygen atoms contained by acetic acid containing 3.2 moles of Carbon is calculated as,
2 moles of C accompany = 2 moles of O
So,
3.2 moles of C will accompany = X moles of O
Solving for X,
X = (3.2 mol C × 2 mol O) ÷ 2 mol C
X = 3.2 mol of Oxygen
Since hydrogen only has 1 electron it shares 1 with flourine to have a pair. It is single bonded.
Answer:
Scientists use the scientific method because it is evidence-based, standardized and objective in conducting experiments. The scientific method allows scientists to stick to facts and to avoid the influence of preconceived notions and personal biases in research processes, improving the credibility of research findings.
Explanation:
The atomic number of Fe= 26
The electronic configuration of Fe will be
1s2 2s2 2p6 3s2 3p6 4s2 3d6
When it loses two electrons to form ferrous ion (Fe(II)) the electrons will be loose by 4s orbital first
So the electronic configuration of Fe^+2 ion will be
1s2 2s2 2p6 3s2 3p6 3d6
Hence there are six electrons in 3d orbital of iron dipositive ion
Now the the electrons in 3d orbital will be like:
so there are four unpaired electrons
