Question

i need to put 5 grams of hydrogen through two sets of chemical reactions, one resulting in a covalent outcome, the other resulting in an ionic outcome. I also need to balance the equations used during this process as well as calculate the number of molecules produced by the covalent compound, and the mass of the ionic product.This is a big project in my chemistry class and I've chosen Hydrogen as my element to use throughout these chemical reactions. I will provide the assignment outline and the work I've done so far :)thank you so very much for the help!

Answer 1

1.For a covalent bond , we will use the equation below:

2H2(g) +O2(g) → 2H2O(g)

Mass = 5 g : :

Moles = 4.96 : : 4.96

1.1 number of moles for hydrogen :

moles = mass /Molecular mass

= 5g/1,00784

=4.96 moles

1.2 Determine molar ratio in oder to get the moles for product 2H2O

we see that :

2 moles of Hydrogen produces: 2 moles of water

so, 4.96 moles of hydrogen will produce : x = 4.96*2 /2 = 4.96

This means that moles for water = 4.96

1.3 Calculating molecules of the product

n = 4.96moles

Molecules of H2O = 4.96 mol * 6.022×10^23molecules/1mol

=2.99x10^24 molecules
