Answer:
nitrogen dioxide
Explanation:
this was on my chemistry test
White crystalline salt contains an ionic bond because it is formed due to the transfer of electrons from one atom to another.
the molarity of KCl solution prepared by dissolving 0.898 mole of KCl in 250 ml water is calculated using the below formula
molarity= moles/volume in liters
moles= 0.898 moles
volume in liters= 250/1000 =0.25 liters
molarity is therefore= 0.898/0.25= 3.592 M
Recorded observations is called data.
