Here is your answer
C3H8 + O2-----> CO2 + H2O
Balancing C atoms
C3H8 + O2------> 3CO2 + H2O
Balancing H atoms
C3H8 + O2------> 3CO2 + 4H2O
Balancing O atoms
C3H8 +

O2------->

CO2 +

H2O
Hence the equation is balanced.

Answer:
38 elements or Element 31: Gallium Element 32: Germanium Element 33: Arsenic Element 34: Selenium Element 35: Bromine Element .
Explanation:
How many transition metals are there?
The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
Answer: The correct answer is Hydrogen Fluoride.
P₄0₆
+ 20₂
⇒ P₄0₁₀
Explanation:
The overall equation for the reaction that produces P₄0₁₀ is :
P₄0₆
+ 20₂
⇒ P₄0₁₀
Now let us derive this equation:
Given equations:
P₄
+ 30₂
⇒ P₄0₆
equation 1;
P₄
+ 50₂
⇒ P₄0₁₀
equation 2;
To get the overall combined equation, the equation 1 must be reversed and added to equation 2:
P₄0₆
⇒ P₄
+ 30₂
equation 3
+
equation 2:
P₄
+ 50₂
+ P₄0₆
⇒ P₄0₁₀
+ P₄
+ 30₂
cancelling specie that appears on both sides and removing excess oxygen gas on the reactant side gives;
P₄0₆
+ 20₂
⇒ P₄0₁₀
