There would be about 1.67 x 10^25 oxygen atoms and about 3.34 x 10^25 hydrogen atoms.
The answer to your question is ‘B
it can form 3 bonds because 1 electron is in each of the 3 2p oribitals.
The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1
so specifically the 2p oribital is :
2px1 2py1 2pz1
hi there bestie [i think its 3]
Answer:
The specific heat capacity of glass is 0.70J/g°C
Explanation:
Heat lost by glass = heat gained by water
Heat lost by glass = mass × specific heat capacity (c) × (final temperature - initial temperature) = 58.5×c×(91.2 - 21.7) = 4065.75c
Heat gained by water = mass × specific heat capacity × (final temperature - initial temperature) = 250×4.2×(21.7 - 19) = 2835
4065.75c = 2835
c = 2835/4065.75 = 0.70J/g°C
