The correct name for the hydrocarbon would be option 2. 2 - methyl - 2 - pentene.
Answer:
1. NaN₃(s) → Na(s) + 1.5 N₂(g)
2. 79.3g
Explanation:
<em>1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN₃) into solid sodium and gaseous dinitrogen.</em>
NaN₃(s) → Na(s) + 1.5 N₂(g)
<em>2. Suppose 43.0L of dinitrogen gas are produced by this reaction, at a temperature of 13.0°C and pressure of exactly 1atm. Calculate the mass of sodium azide that must have reacted. Round your answer to 3 significant digits.</em>
First, we have to calculate the moles of N₂ from the ideal gas equation.

The moles of NaN₃ are:

The molar mass of NaN₃ is 65.01 g/mol. The mass of NaN₃ is:

Answer:Iron(|||) Hydroxide
Explanation:Fe is iron and OH is hydroxide
I'm not sure about 2 but in 3 it would float
Answer:
usually when a river, ocean or lake...etc becomes deeper is because of the weather the more hydrogen and oxygen atoms the more water :D and also gravitys pull thats pulling it deeper is another reason.
