Answer:
glycolysis
Explanation:
The first stage of the aerobic and an-aerobic respiration is glycolysis. In the glycolysis, the glucose molecule breaks down into two three carbon compound pyruvic acid. #answerwithquality #BAL
Explanation:
this molecule does not exhibit any resonance, and even if it does, this structure would be the most viable since the net charge on all of the atoms are 0.
The statement "When using the ideal gas constant value, R = 0.0821, in an ideal gas law calculation, the units of temperature may be expressed as degrees Celsius or <span>Kelvin" is false. It must be Kelvin only not celsius</span>
Answer:
Percent yield = 57.8 %
Theoretical yield = 11.781 g
Explanation:
Given data:
Mass of CaO produced = 6.81 g
Mass of CaCO₃ react = 20.7 g
Theoretical yield = ?
Percent yield = ?
Solution:
Chemical equation:
CaCO₃ → CaO + CO₂
Number of moles of CaCO₃ :
Number of moles = mass/molar mass
Number of moles = 20.7 g/ 100.1 g/mol
Number of moles = 0.21 mol
Now we will compare the moles of CaCO₃ with CaO.
CaCO₃ : CaO
1 : 1
0.21 : 0.21
Theoretical yield of CaO:
Mass = number of moles × molar mass
Mass = 0.21 mol × 56.1 g/mol
Mass = 11.781 g
Percent yield:
Percent yield = ( actual yield / theoretical yield ) × 100
Percent yield = (6.81 g/ 11.781 g) × 100
Percent yield = 57.8 %
