First, we need to state the chemical equation for the combustion of PH3
And the mass of PH3 is 17.0 grams and we need to know the moles.
In the periodic table, the atomic mass of the P (phosphorus) is 31 and the atomic mass of the H (hydrogen) is 1.
So, you sum the mass of P to the mass of H multiplied by 3 and you obtain this:
With this data, we can search the moles of PH3:
Answer:
2
Explanation:
The subscript on Ammoniumwhich is (NH4) is 2.
Hope this helped!
Rust is when a metal turns brown-ish red-ish and that tells you that the metal is old and is no longer useful. we don't want it floating in our bodies because it's rusted metal. hope this helped! :)
Therefore 0.2 moles of sodium (Na) contains 12.046×1023atoms in it.
1. covalent bonds are strong
2. hydrogen bonds are weak
3. Ionic bonds are weak
