Answer:
Ba
Explanation:
The trend for atomic radius is that it increases as you go down and decreases as you go right.
Sorry this isnt an answer but this is a lot of work, if you really need it answered make it worth more points :)
1.) is157.7 g
<span>moles Fe = 209.7 g/ 55.847 g/mol=3.75
the ratio between Fe and CO is 2 : 3
moles CO = 3.75 x 3 /2 =5.63
mass CO = 5.63 mol x 28.01 g/mol=157.7 g
2.) is </span><span>1.06 moles
</span>48.7/23 = 2.12 moles sodium
<span>2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles </span>
1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen.
3.) is 91.8
<span>8.3 moles H2S x (2 moles H2O / 2 moles H2S) = 8.3 moles H2O = theoretical amount produced. </span><span>8.3 moles H2O x (18.0 g H2O / 1 mole H2O) = 149 g H2O produced theoretically. </span><span>% yield = (actual amount produced / theoretical amount) x 100 = (137.1 g / 149 g) x 100 = 91.8 </span>
Answer:
The answer to your question is below
Explanation:
Organic chemistry studies the compounds that have carbon, hydrogen, oxygen and other elements in their structure.
Carbohydrates are biomolecules that are composed of carbon, hydrogen, and oxygen that is why they are studied by organic chemistry.
Other biomolecules that are also studied by organic chemistry are Proteins, Lipids, and Vitamins.
