Yes you balanced it correctly : CH₃CH₂CH₃ ₍g₎ + 5O₂ ₍g₎ -------> 3CO₂ ₍g₎ + 4H₂O ₍g₎
A hack to checking if its correct when they give you the structural formula of one of the species (CH₃CH₂CH₃) is to convert it to the molecular formula and if you get the same answer then it's correct.
So CH₃CH₂CH₃ is the struct-formula for the molec-formula C₃H₈
C₃H₈ + 5O₂ --------> 3 CO₂ + 4H₂O (which means your correct =D)
Answer:
4
Explanation:
The balanced equation for the reaction is as follows:
4Al + 3O2 --> 2(Al2O3)
Mn+2 is cation and CO3 is anion
hope it help
Answer:
Yes
Explanation:
Because they are lighter than water
Answer:
A
Explanation:
Radon is an alpha emitter. It emits alpha particles giving off gamma ray. It is a radioactive byproduct of radium-222.
Radon also penetrates the skin. This is because radon is a gas and chemically unreactive with most materials, it moves easily through very small spaces, such as those between particles of soil and rock, to the soil surface
Option B is wrong. It is produced during radioactive decay of radium and not uranium.
Option C is wrong. Radon is not a metallic element.
Option D is wrong also. It is not produced from photochemical smog
Option E is wrong. This is an extension of option B. Uranium is generally used in nuclear plant operations and not radium
