Answer:
Hydrogen Gas
Explanation:
The hydrogen gas now in the test tube is flammable. So when I hold the tube over the flame, the hydrogen gas ignites and creates a popping sound. It is like a tiny bomb or fireworks.
Hope this helped! :)
2.82 inches is are equivalent to 7.16 cm.
The volume of the cube ;
7.16 × 7.16 × 7.16 = 367.06 cm³
The density of titanium is 4.5 g/cm³
Therefore; mass will be 4.5 × 367.06 = 1651.77 g
1 mole of titanium has 47.867 g
thus, 1651.77 g is equivalent to 1651.77/ 47.867 = 34.507 moles
According to the Avagadro's constant 1 mole = 6.022 × 10∧23 atoms
Therefore, we get 6.022 × 10∧23 × 34.507 = 2.078 ×10∧25 atoms
Hydrogen bonds or covalent but I’m sure it’s hydrogen
