Answer:
1.89 g CaCO₃
Explanation:
You will have to use stoichiometry for this question. First, look at the chemical equation.
Na₂CO₃ + CaCl₂ ==> 2 NaCl + CaCO₃
From the above equation, you can see that for one mole of Na₂CO₃, you will produce one mole of CaCO₃. This means that however many moles of Na₂CO₃ you have in the beginning, you will have the same amount of moles of CaCO₃, theoretically speaking.
So, convert grams to moles. You should get 0.0189 mol Na₂CO₃. This means that you will get 0.0189 mol CaCO₃. I'm not sure what units you want the answer in, but I'm going to give it in grams. Convert moles to grams. Your answer should be 1.89 g.
No, because a natural diamond is a feat of nature and it is amazing how nature made the intricate structure in a diamond. synthetic diamonds are created in laboratory conditions, so it feels less 'amazing' that the diamond was created because each diamond doesn't feel so unique.
However, the molecular structure of both synthetic and natural diamonds are identical, so it is nearly impossible to tell the difference (if you don't know which is which).
Answer:
means that 2 atoms of the element hydrogen have joined together to form w molecule.
Explanation:
a subscript is only used when more than ine atom is being represented.
3.54g H2 means you have 3.54 / 2 = 1.77 moles of H2, which means you have 1.77*2 = 3.54 moles of H atom.
Since 1 mole of NH3 has 3 moles of H, so you can produce 3.54 / 3 moles of NH3, which is (3.54/3) * (12+3) = 17.7 grams
