Answer: C₇H₁₄ + 7O₂ → 7CO + 7H₂O
Explanation:
- For any equation to be balanced the number of (C, H, and O) atoms in the reactants side should be the same in the products side.
- The first choice is wrong because it is unbalanced equation that the reactants side has 22 O atoms and in the products side there is 14 O atoms.
- The second choice is wrong because the incomplete combustion of heptene results CO and/or CO₂ and H₂O.
- The third choice is the right answer that it has 7 atoms of C, 14 atoms of H, and 14 atoms of O in both reactants and products sides.
- The fourth choice is wrong because the combustion of heptene occurs in O₂ not in O.
When iron is heated with sulphur it reacts with it to form a compound which is non magnetic in nature unlike iron which is magnetic in nature
The reaction is
Fe + S --- > FeS
thus due to formation of compound the individual properties of elements taking part in chemical reaction disappears unlike mixtures where properties of two components remains as such.
Answer:
0.5 moles of Pb(OH)₂ are produced.
Explanation:
The reaction is:
If we have 1.0 liter of 1.0 M of sodium hydroxide and lead (II) nitrate, the number of moles are:
Now, we need to find the limiting reactant knowing that 2 moles of sodium hydroxide react with 1 mol of lead (II) nitrate:
Since we have 1 mol of sodium hydroxide and we need 2 moles to react with lead (II) nitrate, then the limiting reactant is sodium hydroxide.
We can find the number of moles of lead (II) hydroxide produced as follows:
Therefore, 0.5 moles of Pb(OH)₂ are produced.
