Answer : The balanced half-reaction in a basic solution will be,
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Rules for the balanced chemical equation in basic solution are :
First we have to write into the two half-reactions.
Now balance the main atoms in the reaction.
Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion at that side where the less number of hydrogen are present.
Now balance the charge.
- Now balance the oxygen atoms.
- Now balance the hydrogen atoms.
The balanced half-reaction in a basic solution will be,
Answer:
The formula mass of Na2S04 is 142.04 g/mol
You have to find how many moles of H2 has formed.
C+ H2O -> CO + H2
mole of carbon reacted = mass / molar mass = 34g/ 12g per mol = 2.83 mol
for every 1 mole of carbon will form 1 mole of H2
mole of hydrogen produced = 1* 2.83 = 2.83 mol
mass of hydrogen = mole * molar mass = 2.83 mol * (1*2) = 5.66g
Answer:
1–ethoxybutane
Explanation:
In naming the above compound, the following must be observed:
1. The longest chain gives the root name of the compound.
2. The shorter chain is named as substituent together with the oxygen group as alkoxy.
3. Locate the position of the alkoxy group by giving it the lowest low count.
4. Combine the above to obtain the name of the compound.
Now we shall name the compound as follow:
1. The longest chain is carbon 4 i.e butane.
2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.
3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.
4. The name of the compound is:
1–ethoxybutane.
