Assuming constant pressure and temperature, how many moles of gas have been added to the initial 3 moles of gas when the volume

Temka [501]

We first assume that the gas is ideal which is a safe assumption to approximate the answer to the problem. Then we need to know the ideal gas equation and that is:

PV=nRT
where
P- pressure
V- volume
n-number of moles-
R- ideal gas constant
T-temperature.

Since we know that P, T and V are constant, rearranging the equation would lead to:

P/TR = n/V or the ratio of the moles of gas and volume is constant.

(3moles)/2L = (3+x)/4L
where
x is the additional moles.

Solving for x = 3 moles.

Write balanced equations for all the reactions in the catabolism of glucose to two molecules of glyceraldehyde 3-phosphate (the

Reil [10]

Solution :

The balanced chemical equation are

The Catabolism of the glucose takes place in five stages :

1. Glucose + $ATP$ → glucose - $6$ - phosphate $+ ADP$ , $\Delta G^0=-16.7 \ kJ/mol$

2. Glucose - $6$ - phosphate → Fructose - $6$ - phosphate , $\Delta G^0=1.7 \ kJ/mol$

3. Glucose - $6$ - phosphate + $ATP$ → $ADP$ + Fructose - $1,6- \text{biophosphate}$ , $\Delta G^0=-14.2 \ kJ/mol$

4. Fructose - $1,6- \text{biophosphate}$ → dihydroxyacetonephosphate + glyceraldehyde $-3 -$ phosphate, $\Delta G^0=23.8 \ kJ/mol$

5. Dihydroxyacetonephosphate → glyceraldehyde $-3 -$ phosphate , $\Delta G^0=7.5 \ kJ/mol$

Therefore, the overall net equations

Glucose + $2ATP \rightarrow$ glyceraldehyde $-3 -$ phosphate + $2ADP$ $\Delta G^0=2.1 \ kJ/mol$

We add 1.4 moles to 700 mL of water. What is the molarity

Nastasia [14]

Answer:

Molarity= 2M

Explanation:

n=1.4, V= 700ml= 0.7dm3

n= CV

1.4= C×0.7

C= 1.4/0.7= 2M

Which compound has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1?

rewona [7]

$CH_{3}COCH_{3}$ (acetone) has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1

Acetone is a synthetic substance that is also naturally present in the environment. It is a tasteless, colourless liquid with a distinct odour. It is combustible, readily evaporates, and dissolves in water. It is also known as beta-ketopropane, 2-propanone, and dimethyl ketone. Plastic, fibres, medications, and other compounds are all made from acetone.

Other substances can also be dissolved with it. It is a byproduct of the breakdown of human fat and is found naturally in plants, trees, volcanic gases, forest fires, and other organisms. It can be found in landfills, tobacco smoke, and automobile exhaust. Acetone is released into the environment more through industrial processes than through natural ones.
