Answer:
The name of this compound is :
Bi2(CO3)3 = Bismuth Carbonate
Explanation:
The name of the compound is derived from the name of the elements present in it.
The rule followed while naming the compound are:
1. The first element (always the cation) is named as such .
2. The second element (The anion) end with "-ate , -ide ," etc
3. NO prefix is added while naming the first element.
For example : Bi2 can't be named as Dibismuth
Na2 = Can't be named as disodium
Hence the compound :
Bi2(CO3)3 contain two element : Bi and CO3. Here , Bi = cation (named as such) and CO3 = anion (named according to rules)
Bi = Bismuth
CO3 = carbonate
Bi2(CO3)3 = Bismuth Carbonate
The molecular mass of this compound is :
Molecular mass = 2 (mass of Bi) + 3(mass of C) + 6(mass of O)
= 2 (208.98)+3(12.01)+6(15.99)
= 597.987 u
Answer:
The products are CO₂ and H₂O.
The ballanced equation is this:
2C₄H₆ + 11O₂ → 8CO₂ + 6H₂O
Explanation:
In any chemical reaction, where you see that you have a compound reacting only with oxygen (O₂), you are in front of combustion.
Products in combustion are always water vapor and carbon dioxide.
Take a look to the methane combustion.
CH₄ + 2O₂ → CO₂ + 2H₂O
1 mol of methane reacts with 2 moles of oxygen to form 1 mol of CO₂ and 2 moles of water.
This is the combustion for an alkene where 2 moles of the alkene reacts with 11 moles of oxygen to make water and CO₂ like this:
2C₄H₆ + 11O₂ → 8CO₂ + 6H₂O
