Covalent solid, such as candle wax.
Answer:
2.5 moles of H2
Explanation:
First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is shown below:
2H2 + O2 —> 2H2O
From the equation above,
2 moles of H2 produced 2 moles of H2O.
Therefore, 2.5 moles of H2 will produce 2.5 moles of H2O
Answer:
6.627 x10^26 electrons
Explanation:
Each Na atom has 11 electrons
Mole weight = 22.989 gm/mole
2300gm /22.989 gm/mole * 6.022 x 10^23 atoms/mole * 11 electrons/atom
= 6.627 x 10 ^26 electrons
