D-number of electrons in the outer energy level.
Answer: This is called moles
Explanation: This is described to be the number of molecules, atoms or ions in a substance :)
Answer:
120000drops
Explanation:
Average blood in human blood = 6L - 6*1000 = 6000ml
1 ml of blood is equal to 20 drops
6000ml of blood makes 20*6000 = 120000 drops
Very simply, you get twice as much Hydrogen as Oxygen, because the chemical formula is H2O, meaning two hydrogen atoms bonded to one oxygen atom.
Answer:
H₂O
Explanation:
Based electronegativity, water H₂O will have the higher melting point from the given choices. The binding force between hydrogen and oxygen is greater than for the others.
- In group 6, oxygen has the highest electronegativity.
- It pulls the shared electron closer in the bond.
- The high electronegativity between hydrogen and oxygen causes the elevated melting point between the two species.
