Answer:
2.67 g/mL
Explanation:
Initial Volume of water = 10.0 mL
Final Volume pf water = 15.46 mL
Mass = 14.74g
Density = Mass / Volume of aluminium
Volume of aluminium = Final Volume of water - Initial Volume of water = 15.46 - 10 = 5.46mL
Density = 14.74 / 5.46 = 2.67 g/mL
Answer:
The first 5 are exothermic reaction because heat is in product means heat is evolved or given out.
And last no reaction shows that heat is required so last reaction is endothermic reaction.
Explanation:
And heat is evolved in exothermic reaction and heat is absorbed in endo thermic reaction
HALOGENS have 7 electrons in their final shell regardless if the total number of atoms. These 7 electrons would be shared between the 's' and 'p' orbital in the form
ns² np⁵ (the same as the question). Attached is a table that highlights the fact that halogens have the same form in terms of the valence electrons.
Answer:
