2Fe(s) + O2(g) → 2FeO(s)<br><br><br> To which category does this reaction belong?
Varvara68 [4.7K]

Answer:

Redox reactions

Explanation:

Redox reactions consists of both oxidation and reduction

one species gets oxidised and other species become reduced, both oxidation and reduction happen simultaneously

reduction is either gain of electrons or gain of hydrogen. in reduction the oxidation number of species reduces

in this reaction the reduction half equation is

O₂ + 4e --> 2O²⁻

oxidation is either loss of electrons or gain of oxygen. in oxidation the oxidation number of species increases.

Fe --> Fe²⁺ + 2e

since both these half reactions happen overall its a redox reaction

Determine the volume in liters occupied by 14g of nitrogen gas STP
stealth61 [152]
Molar mass N₂ = 28.0 g/mol

Number of moles:

n = mass / molar mass

n = 14 / 28.0

n = 0.5 moles

1 mole N₂ -------- 22,4 ( at STP)
0.5 mole N₂ ------- ?? Liters

L = 22.4 * 0.5 = 11,2 L

hope this helps!

An alkene adds hydrogen in the presence of a catalyst to give 3,4-dimethylhexane. Ozonolysis of the alkene followed by treatment
slamgirl [31]

The structure of alkene is given below in the image.

Alkenes are described as both branched or unbranched hydrocarbons that possess at least one carbon-carbon double bond (CC) and feature a popular system of CnH2n [1].

Alkanes are organic compounds that encompass single-bonded carbon and hydrogen atoms. The formulation for Alkanes is CnH2n+2, subdivided into 3 companies – chain alkanes, cycloalkanes, and branched alkanes.

The geometry around each carbon atom is based totally on a trigonal planar shape, due to the fact, that each carbon has three electrons around it. This must make the angle of each bond one hundred twenty.
