A phase diagram is a temperature vs pressure plot from which the phase of a compound can be deduced under the given temperature and pressure conditions. The 3 equilibrium curves: Solid-Gas, Liquid-Gas and Solid-Liquid separate the compound into the three states of matter. The 3 states can however coexist at a unique point referred to as the triple point.

Based on the phase diagram for CO2 (which is readily available online), at -70 C and 5.5 atm, CO2 exist as a solid.

Converting, -70 degrees centigrade is equal to 9/5 x C+32= 158 degrees Fahrenheit and cO2 freezes at -108.5 degrees Fahrenheit so the CO2 will be in solid form at this temperature or what is commonly known as the form 'dry ice'.

Hydrogen gas and oxygen gas combine to form water. How many grams of oxygen are needed to react with 45.7 grams of hydrogen ?

Julli [10]

The balanced equation:
2 H₂ + O₂ → 2 H₂O

moles of Hydrogen = mass of hydrogen ÷ molar mass of hydrogen
= 45.7 g ÷ 2 g/mol
= 22.85 mol

Now, the mole ratio of O₂ : H₂ is 1 : 2
which means that there are two times as much moles of H₂ as O₂ taking
part in the reaction

Thus since moles of H₂ = 22.85 mol
then moles of O₂ = 22.85 ÷ 2 = 11.425 mol

Mass of O₂ = moles of O₂ × molar mass of O₂

= 11.425 mol × 32 g/mol

= 365.6 g

∴ <span>grams of oxygen are needed to react with 45.7 grams of hydrogen is 365.6g</span>

In the electron transport system, hydrogen atoms removed from NADH ultimately end up as part of __________. In the electron tran

guajiro [1.7K]

<h3>Answer:</h3>

Water

<h3>Explanation:</h3>

The electron transport chain is the third and the last phase of aerobic cellular respiration in living organisms.
During the electron transport chain, electron carriers NADH and FADH₂ are used to generate energy in the form of ATP.
During this phase, energy is generated through oxidative phosphorylation in the inner membrane of the mitochondrion.
In the electron transport chain, hydrogen ions are transferred from NADH and FADH₂ and ultimately end up as part of water.

A. draw the structure of the tetrahedral intermediate initially formed in the reaction shown. you do not have to consider stereo

julsineya [31]

The reaction is shown below, Acid protonates the carbonyl oxygen and makes the carbonyl carbon more electrophilic. Water attacks on activated carbonyl group and forms a tetrahedral intermediate.

Intermediate:
Structure of Intermediate is shown both in 2-D and 3-D (below attached).

Carbonyl group is regenerated with the elimination of ethanol.

Reaction is as below, The final product is carboxylic acid.
