Answer:
1/3
Explanation:
Pyruvate is produced by the glycolysis in cytoplasm. The oxidation of pyruvate takes place in mitochondrial matrix.
Pyruvate is converted to acetyl-CoA in the reaction given below:
Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂
1 molecule of carbon dioxide is eliminated from 1 molecule of pyruvate.
Also,
2 molecules of carbon dioxide is eliminated from 2 molecules of pyruvate (as glucose on glycolysis yields 2 molecules of pyruvate).
Also, acetyl-CoA further goes into the citric acid cycle and produces 2 molecules of carbon dioxide.
Thus pyruvate produces total 3 molecules of CO₂ and hence glucose produces 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate)
Thus,
<u>Fraction = 2/6 = 1/3</u>
Specif gravity = density of the material / density of water
density of the material = specific gravity * density of water
density of gold = 19.3 * 1 g/mL = 19.3 g/mL
density = mass / volume ==> Volume = mass / density
Volume = 0.4 kg * 1000 g/kg / 19.3 g/mL = 20.725 mL
Length of one side of the cube =
![\sqrt[3]{20.725 {cm}^{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B20.725%20%7Bcm%7D%5E%7B3%7D%20%7D%20)
= 2.75 cm
Pass cm to inches
2.75 cm * 1 inch / 2.54 cm = 1.08 inch
Answer:
The correct answer is because they have same number of protons but different number of neutrons.
Explanation:
Isotopes are atoms of the same element but differ only in the number of neutrons in the nucleus, i.e. they have same atomic number but different mass number.
Mass number is affected as they have different number of neutrons, thus effecting their physical properties.
The number of electrons and protons are same, i.e. their atomic number is same and thus their chemical properties are same as chemical properties are determined by the atom’s electronic configuration and that relates to number of protons.
<u>Answer:</u> The additional information that is helpful in calculating the mole percent of XCl(s) and ZCl(s) is the molar masses of Z and X
<u>Explanation:</u>
To calculate the mole percent of a substance, we use the equation:
![\text{Mole percent of a substance}=\frac{\text{Moles of a substance}}{\text{Total moles}}\times 100](https://tex.z-dn.net/?f=%5Ctext%7BMole%20percent%20of%20a%20substance%7D%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20a%20substance%7D%7D%7B%5Ctext%7BTotal%20moles%7D%7D%5Ctimes%20100)
Mass percent means that the mass of a substance is present in 100 grams of mixture
To calculate the number of moles, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%7BMolar%20mass%7D%7D)
We require the molar masses of Z and X to calculate the mole percent of Z and X respectively
Hence, the additional information that is helpful in calculating the mole percent of XCl(s) and ZCl(s) is the molar masses of Z and X
Answer:
meter the mean free path of hydrogen atoms in interstellar space.Explanation:
The mean free path equation is given as:
![\lambda =\frac{1}{\sqrt{2}\pi d^2 n}](https://tex.z-dn.net/?f=%5Clambda%20%3D%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%5Cpi%20d%5E2%20n%7D)
Where"
d = diameter of hydrogen atom in meters
n = number of molecules per unit volume
We are given: d = 100 pm = ![100\times 10^{-12}= 10^{-10} m](https://tex.z-dn.net/?f=100%5Ctimes%2010%5E%7B-12%7D%3D%2010%5E%7B-10%7D%20m)
![n = 1 m^{-3}](https://tex.z-dn.net/?f=n%20%3D%201%20m%5E%7B-3%7D)
![\lambda =\frac{1}{\sqrt{2}\pi (10^{-10} m)^2\times 1 m^{-3}}](https://tex.z-dn.net/?f=%5Clambda%20%3D%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%5Cpi%20%2810%5E%7B-10%7D%20m%29%5E2%5Ctimes%201%20m%5E%7B-3%7D%7D)
![\lambda =2.2508\times 10^{19} m](https://tex.z-dn.net/?f=%5Clambda%20%3D2.2508%5Ctimes%2010%5E%7B19%7D%20m)
meter the mean free path of hydrogen atoms in interstellar space.
