Answer:
The "word equation" is Magnesium + Dioxygen → Magnesium Oxide
Explanation: This is also the same as Mg + O₂ → MgO.
The percent composition of hydrogen is 18.3%.
What is percent composition?
The term percent composition refers to the percentage of a particular component in a compound. It is contained as the ratio of the mass of that component to the total mass multiplied by 100.
From the law of conservation of mass, total mass of beryllium hydride(BeH2) = 85.2 g
Mass of hydrogen = 15.6 g
Percent composition of hydrogen = 15.6 g/ 85.2 g × 100/1 = 18.3%
No it will be a 10% of that balance so take 16 * 10% and then take that answer and divide bye 70%
A distillation column is a process unit in which a feed mixture is separated by multiple partial vaporizations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture (the ones that vaporize most readily).
