Answer:
C3H8 + 5O2 => 3CO2 + 4H2O
Explanation:
Hydrocarbon combustion is the reaction between a hydrocarbon and O2 producing CO2 and water.
C3H8 + O2 => CO2 + H2O
First we balance the C and H.
C3H8 + O2 => 3CO2 + 4H2O
Now we balance O for the answer!
C3H8 + 5O2 => 3CO2 + 4H2O
Answer:
+4
Explanation:
Hello,
In this case, considering nitrogen dioxide's formula:
And due to the fact that oxygen's oxidation state is -2 in this case, we could find nitrogen's oxidation state in nitrogen dioxide by using a balance charge:
For that reason, nitrogen's oxidation state is +4:
Best regards.
Answer:
Electron-pair geometry: tetrahedral
Molecular geometry: trigonal pyramidal
Hybridization: sp³
sp³ - 4 p
Explanation:
There is some info missing. I think this is the original question.
<em>For NBr₃, What are its electron-pair and molecular geometries? What is the hybridization of the nitrogen atom? What orbitals on N and Br overlap to form bonds between these elements?</em>
<em>The N-Br bonds are formed by the overlap of the ___ hybrid orbitals on nitrogen with ___ orbitals on Br.</em>
<em />
Nitrogen is a central atom surrounded by 4 electron domains. According to VESPR, the corresponding electron-pair geometry is tetrahedral.
Of these 4 electron domains, 3 represent covalent bonds with Br and 1 lone pair. According to VESPR, the corresponding molecular geometry is trigonal pyramidal.
In the nitrogen atom, 1 s orbital and 3 p orbitals hybridize to form 4 sp³ orbitals for each of the electron domains.
The N-Br bonds are formed by the overlap of the sp³ hybrid orbitals on nitrogen with 4p orbitals on Br.
Answer:
Volcanologists can predict eruptions if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
