Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.

What are the three types of seismic waves?

Softa [21]

Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S wavespenetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as "body waves".

Using your old and new reaction roadmaps as a guide, show how to convert ethane into 1- butanol. You must use ethane as the sour

Naddik [55]

Answer:

Ethane can be converted into 1- butanol in 4 different steps and reactions.

Explanation:

Step 1 : Ethane follows Markovnikov's rule and reacts with a protic acid called Hydrogen chloride to form Chloroethane.

Step 2: Chloroethane undergoes Wurtz reaction where it reacts with sodium metal in the presence of dry ether to form an higher alkane called butane.

Step 3: Butane undergoes chlorination where it reacts with an halogen called chlorine to form 1-chlorobutane.

Step 4: 1-chlorobutane reacts strong aqueous Potassium hydroxide (KOH) to form 1-butanol.

Attached to this answer is the handwritten conversion of Ethane to 1-butanol showing all the reagents and molecules synthesized along the way.
