Lead (II) chloride+ potassium nitrate
PbCI2+KNO3(B)
Answer:
Protons 4 or 5 are most acidic.
Explanation:
As mentioned there are four types of hydrogen in Hexane-2,4-dione.
The numbering are shown in the figure for your better understanding.
As shown in the figure if we remove the proton from carbon number 3 (protons number 4 or 5), it will result in formation of a carbanion. This carbanion is stabilized due to presence of -I group oxygen and there is possibility of resonance (as shown).
Thus protons 4 or 5 are most acidic.
Answer:
Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂
Explanation:
There are many ways to balance a chemical equation. In this case, I will show you the algebraic method:
The first step is assign a letter to each compound:
a Fe₂O₃ + b CO → c Fe + d CO₂
Then, you must write the balance equations for each atom, thus:
<em>Fe: 2a = c</em>
<em>C: b = d</em>
<em>O: 3a + b = 2d</em>
The last step is assign a value to a letter. I, for example, will say that <em>a is 1, </em>and then find the values for the others letters, thus:
<em>Fe: 2a = c </em>if <em>a=1; c=2</em>
<em>O: 3a + b = 2d </em>if <em>a=1 → 3+b = 2d</em>
As b = d → <em>3+d = 2d; 3 = 2d - d; </em>3=d and 3=b
Thus, the balanced equation is:
Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂
I hope it helps!
