Two ATP were created, two NAD+ were converted to two NADH + H+, and two glucose molecules were divided into two pyruvate molecules during the glycolysis process.

Anaerobic glycolysis predominates when there is no oxygen present (anaerobic conditions) and in cells without mitochondria. As lactate dehydrogenase reoxidizes NADH to NAD+, the pyruvate is degraded to lactate. Erythrocytes, which lack mitochondria, rely on this mechanism as a major source of ATP.

Pyruvate will go through a process known as fermentation when oxygen is absent or if an organism is unable to engage in aerobic respiration.

The specific heat capacity of a material can be defined as the quantity of heat required to raise the temperature in one unit of material by one-degree Celcius.

When the heat is lost or absorbed, the temperature of the material will be changed following the equation:

Q = mCΔT

Given, the amount of energy absorbed, Q = 18.942 KJ

The mass of the substance, m = 345 g

The change in the temperature = 167.7 - 45 = 122.7°C

The specific heat for the given substance can be determined as:

18.942 × 1000 = 345 × C × 122.7

Answer:

4.67 liters of SO2 with sig figs

Explanation:

To do this reaction, we first must find the limiting agent.
in this problem, 5 liters of H2S are reacted with 7 liters of O2, and each two moles of H2S corresponds to 3 moles of O2. Assuming ideal behavior, 1 liter of H2S has the same number of moles as 1 liter of O2 has. So, 2 liters of H2S react with 3 liters of O2. To find the limiting reagent, focus on one reagent and calculate how much of the other reagents would be needed to fully consume that one reagent.
Focus on H2S:
5 liters of H2S would require 7.5 liters of O2 (since each 2 liters of H2S requires 3 liters of O2)

Focus on O2:
7 liters of O2 would require 14/3, or 4.666... liters of H2S.

Since we don't have 7.5 liters of O2 (we only have 7 liters) to react with all 5 liters of H2S, we would say that O2 is the limiting reagent, and that we have 7 liters of it.

Next, figure out how much product can be produced per mole of that limiting reagent. 3 moles of O2 and 2 moles of H2S turns into 2 moles of SO2 and 2 moles of H2O. Thus, the ratio of O2 to SO2 is 3:2
We have 7 liters of O2, and since the ratio of O2 to SO2 is 3:2, we can set up the equation:
7:x = 3:2 where x is the number of liters of SO2
cross multiply (or solve with another method) to get:
x = 14/3, or 4.666... liters of SO2

Answer: 0.5643 mol NaOH

Explanation:

First, I would start off with plugging in what you can for the molarity equation, which is:

M = mol/L

So, since you have 0.285M and 1.98 L you can plug that in where it fits. So it’d be:

0.285M = mol/1.98L

To isolate the mols on one side of the equation, you multiple both sides by 1.98 L. (Because it’s in the denominator. If you were trying to find L, you would divide by # of mols since it’s in the numerator).

After multiplying, your final answer should be 0.5643 mols of NaOH.

Dew point for a day's weather is calculated to be 18°C, then the statement that is true based on the dew point is a)Water will condense if the air temperature drops below 18°C.

Dew point is that temperature to which air must be cooled to become saturated with water.

When it is cooled below the dew point, moisture capacity is reduced and water vapor will condense to form dew. When this takes place via contact with colder surface, dew will form on surface.

Dew point is affected by humidity. When there is more moisture in air , then dew point is higher.

Answer:

C) High pressure and low temperature

Explanation:

Le Chatelier's principle. There are 4 mols of gas on the reactants side and 2 moles of gas on the products, as well as some heat. By Le Chatelier's principle, if you increase the pressure (by presumably decreasing the volume), then equilibrium will push to the side with fewer moles, in this case ammonia. Since heat is on the products side, it works like a product. If you take away a product (decreasing temperature/product), then the reaction will push to ammonia to make up for the loss.

Answer:

3.02 atm

Explanation:

To find the final pressure, you need to use the Combined Gas Law:

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the final pressure, volume, and temperature. You first need to convert the temperatures from Celsius to Kelvin (1°C = 273 K). You should convert the initial pressure from kPa to atm (1 atm = 101.3 kPa).

P₁ = 536 kPa / 101.3kPa  =  5.29 atm         P₂ = ? atm

V₁ = 2.50 L                                                  V₂ = 3.75 L

T₁ = 75.0 °C + 273 = 348 K                         T₂ = 25.0°C + 273 = 298 K

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]                                                       <----- Combined Gas Law

[tex]\frac{(5.29atm)(2.50L)}{348K}=\frac{P_2(3.75L)}{298K}[/tex]                                 <----- Insert values

[tex]0.0380=\frac{P_2(3.75L)}{298K}[/tex]                                             <----- Simplify left side

[tex]11.32 = P_2(3.75L)[/tex]                                             <----- Multiply both sides by 298 K

A player can obtain the desired outcome by sticking to their initial strategy, according to the Nash equilibrium, a decision-making theorem in game theory. Each player's approach in the Nash equilibrium is the best one given what the other players have decided.

A Nash equilibrium is a situation in which no participant would profit from altering their current course of action. This implies that even if a player were to know the plans of every opponent, they would still decide to stick with their original plan. Assuming that the other players maintain their initial plans, a player does not benefit from changing their approach under the Nash equilibrium. There could be several Nash equilibria in a game, or none at all. One of the fundamental ideas in game theory is Nash equilibrium.

Assign A the probability of playing H and (1p) of playing T, and B the probability of playing H and (1q) of playing T to calculate the mixed-strategy Nash equilibrium. In this game, the mixed-strategy Nash equilibrium is for each player to select H or T at random with p = 1/2 and q = 1/2.
