Oh fun, stoichiometry. So the equation for this is C8H18+O2----> CO2+H2O, or
2C8H18+25O2----> 16CO2+18H2O when balanced. 10/114.229 g/mol = .087543... mol, converting to moles by dividing by molar mass. The ratio is 25/2, using the integers in front of the molecules in the balanced equation. so you just multiply .087543... by the ratio. That's 1.09429, which you multiply by the molar mass of O2, 31.9988 g/mol. The answer is 35.02 g O2
As the intermolecular forces get weaker, the amount dissolved decreases. Ammonia can form hydrogen bonds with water thus allowing it to be more soluble. CO2 and O2 can only react through London forces, but since CO2 has a higher molecular mass, more electrons, it will have a larger in magnitude temporary dipole moment. This results in the CO2 being more soluble in water than O2.
The overall trend in solubility is NH3>CO2>O2
Answer:
In the order appearing in the question: 4, 1 and 1.
Explanation:
The stoichiometry of the conversion of pyruvate into CO2 shows that 1 mol of pyruvate also yields 4 moles of NADH, 1 mol of FADH2 and 1 mol of ATP.
Answer is: mass of water is 1,35 grams.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
m(H₂) = 9,5 g.
n(H₂) = m(H₂) ÷ M(H₂).
n(H₂) = 9,5 g ÷ 2 g/mol.
n(H₂) = 4,75 mol.
m(O₂) = 1,2 g.
n(O₂) = 1,2 g ÷ 32 g/mol.
n(O₂) = 0,0375 mol; limiting reactant.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 0,0375 mol · 2 = 0,075 mol.
m(H₂O) = 0,075 mol · 18 g/mol.
m(H₂O) = 1,35 g.
Answer:
The labels are not given to represent but the correct answer would be one of these:
-Uses energy
- low concentration to high concentration movement
Explanation:
Active transport and passive transport both are transport methods of the molecules and substances in or out of the cell through the cell membrane. Passive and active transport has only one thing which is the movement of the substance through or across the cell membrane.
However, there are differences in these types of diffusion are:
Active Transport Passive Transport
-Uses energy - a form of diffusion
-Moves from low to high concentration - from high to low concentration
