Law Incorporation [45]

 The much hydrogen that is  produced   is 0.02 mol  of H₂ (answer  B)

 Explanation

2K +2H₂O→ 2 KOH + H₂

 Use the mole ratio to determine the moles of H₂

 From equation above the  K :H₂  is  2:1

Therefore the moles of H₂ = 0.04 x 1/2 = 0.02  mol  of H₂

1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?
UNO [17]
When two compounds have same molecular formula but different structural formula, they are said to be isomers of each other and this phenomenon is called as isomerism. 

Hexane has six isomers.

The isomers of hexane have a difference in their structure due to parent chain length (chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.

A lab technician mixed a 550 ml solution of water and alcohol. if​ 3% of the solution is​ alcohol, how many milliliters of alcoh
kupik [55]

The solution 550 ml total and first we will find the amount of alcohol. 3% = 0.03 550 ml x .03 = 16.5 ml alcohol
 Then to find the amount of water used, we just have to subtract the amount of alcohol from the total volume  
550 ml total - 16.5 ml alcohol = 533.5 ml water
