sammy [17]3 years ago

In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.

How is a new moon the same as or different from a total lunar eclipse
yarga [219]

Explanation:

Both new moon and lunar eclipse occur when the moon is in the same plane the sun and the earth. However, both are different because of the relative position of the moon in its orbit – relative to earth. In a new moon, the moon is in between the earth and the sun, while in a lunar eclipse, the earth us in between the moon and the sun.

During strenuous exercise, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in skeletal muscle must be r
ludmilkaskok [199]

The most important reaction involved in the reoxidation of NADH is Pyruvate → lactate

Two ATP were generated as a net result of glycolysis, two NAD+ were converted to two NADH + H+, and two glucose molecules were divided into two pyruvate molecules.

Pyruvate will go through a process called fermentation when oxygen is absent.

The NADH + H+ from glycolysis will be recycled back to NAD+ during fermentation, allowing glycolysis to proceed.

NAD+ is converted during the glycolysis process into NADH + H+.

Glycolysis cannot proceed without the presence of NAD+.

The NADH produced during glycolysis will be oxidised to create new NAD+ during aerobic respiration, when it will be used once more in glycolysis.

Pyruvate will undergo oxidation in the absence of oxygen or if an organism is unable to engage in aerobic respiration.

Hence The most important reaction involved in the reoxidation of NADH is Pyruvate → lactate

Container A holds 717 mL of an ideal gas at 2.80 atm. Container B holds 174 mL of a different ideal gas at 4.30 atm. Container A
horsena [70]

Answer:

3.09 atm

Explanation:

Given that:

Volume of container A = 717 mL

Pressure of container A = 2.80 atm

Volume of container B = 174 mL

Pressure of container B = 4.30 atm

Now, if the valve are being removed and the gases are allowed to mix together; then

The total final pressure can be calculated by using the formula:

P_f = \dfrac{P_AVA+P_BV_B}{V_A+V_B}

P_f = \dfrac{2.80*717+4.30*174}{717+174}

P_f = \dfrac{2007.6+748.2}{891}

P_f = \dfrac{2755.8}{891}

\mathbf{P_f =3.09 \ atm}
