Answer:
2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)
Explanation:
The balanced equation for the reaction between butane and oxygen to produce carbon dioxide and water can be written as follow:
C₄H₁₀ + O₂ —> CO₂ + H₂O
Next, we shall balanced the equation. This is illustrated below:
C₄H₁₀ + O₂ —> CO₂ + H₂O
There are 4 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 4 before CO₂ as shown below:
C₄H₁₀ + O₂ —> 4CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:
C₄H₁₀ + O₂ —> 4CO₂ + 5H₂O
There are 2 atoms of O on the left side and a total of 13 atoms on the right side. It can be balance by writing 13/2 before O₂ as shown below:
C₄H₁₀ + 13/2O₂ —> 4CO₂ + 5H₂O
Multiply through by 2 to express in whole number ratio.
2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)
Thus, the equation is balanced.
A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons<span> instead of the usual two. The most common double bond, that is between two </span>carbon atoms<span>, can be found in </span>alkenes<span>. Many types of double bonds exist between two different elements.</span>
The part of the atom that accounts for electricity is the electron. As it also determines the properties.
Answer: Electrons
<span>A spectator ion is an ion that exists in the same form on both the reactant and product sides of a chemical reaction.</span>
Answer is: 158,5 km.
<span>1.87e3 m is 1870 m /1000 = 1,87 km.
</span><span>24 m is 24 / 1000 = 0,024 km.
</span><span>5.43e-1 km is 0,587 km.
</span><span>1.561e2 km is 156,1 km.
</span>summing: 1,87 km + 0,024 km + 0,587 km + 156,1 km = 158,5 km.
e3 means 10³ (10 · 10 · 10 = 1000).
