How are lactic and alcoholic fermentation similar?

1 answer:

8 0

Lactic and alcholic happens when there is no oxygen.

So, how did it happen?
Recall that in glycolysis of cellular respiration, there is a glucose (6 Carbons) molecule. That glucose molecule is going to be broken down into two pyruvates (3 Carbons). There is no oxygen (also know as anaerobic respiration) so pyruvate is going to be converted into lactate or alcoholic fermentation depending on it's accessibility. I highly suggest you to watch this video if you don't get what I'm talking about:

Give all possible ml values for orbitals that have each of the following: (a) l = 3; (b) n = 2; (c) n = 6, l = 1.

larisa86 [58]

Answer : All possible values of 'ml' for the following orbitals are:

(a) At l = 3, $m_l=+3,+2,+1,0,-1,-2,-3$

(b) l = 0, 1

At l = 0, $m_l=0$

At l = 1, $m_l=+1,0,-1$

(c) At l = 1, $m_l=+1,0,-1$

Explanation:

There are 4 quantum numbers :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from $(-l\text{ to }+l)$ . When l = 2, the value of $m_l$ will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as $m_s$ The value of this is $+\frac{1}{2}$ for upward spin and $-\frac{1}{2}$ for downward spin.

(a) l = 3 then the value of 'ml' is,

At l = 3, $m_l=+3,+2,+1,0,-1,-2,-3$

(b) n = 2 then the value of 'ml' is,

l = 0, 1

At l = 0, $m_l=0$

At l = 1, $m_l=+1,0,-1$

(c) n = 6 and l = 1 then the value of 'ml' is,

n = 6

l = 0, 1, 2, 3, 4, 5

At l = 1, $m_l=+1,0,-1$

How does the law of conservation of mass apply to this reaction C2H4 + O2 > 2H2O + 2CO2

Sindrei [870]

Coefficients are used here to balance the number of elements in the products and reactants. Coefficients are numbers that are placed in front of a chemical formulas in an equation. Hope it's useful.

Discuss the four impure forms of carbon

seraphim [82]

Various structures, or allotropes, of carbon, are precious stone, graphite, and fullerenes. In jewel, every carbon iota is attached to four other carbon iotas, shaping an unbending construction that makes precious stones hard.

A 3.42 gram sample of an unknown gas is found to occupy a volume of 1.90 L at a pressure of 547 mm Hg and a temperature of 33 °C

liq [111]

Use the Ideal Gas Law to find the moles of gas first.

Be sure to convert T from Celsius to Kelvin by adding 273.

Also I prefer to deal with pressure in atm rather than mmHg, so divide the pressure by 760 to get it in atm.

PV = nRT —> n = PV/RT
P = 547 mmHg = 547/760 atm = 0.720 atm
V = 1.90 L
T = 33°C = 33 + 273 K = 306 K
R = 0.08206 L atm / mol K

n = (0.720 atm)(1.90 L) / (0.08206 L atm / mol K)(306 K) = 0.0545 mol of gas

Now divide grams by mol to get the molecular weight.

3.42 g / 0.0545 mol = 62.8 g/mol
