Answer:
Sun
Explanation:
The closest star from the Earth is the sun.
2Na + 2H2O ----> H2 + 2Na(OH)
48.7/23 = 2.12 moles sodium
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles
1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen
The answer is - 4 thats the charge of Si O
⁴ ¹0
Use the following equation:
Given # of moles * molar mass (g) per mol = Mass (g)
This gives us 11.9 x <span> 51.9962 (g) per mol.
618.75 moles</span>
