Answer:

The second process can occur without a net influx of energy from some other process C6H12O6+6O2-->6CO2 +6H2O

Explanation:

Energy is stored in form of ATP and the inverse reaction is a process of photosynthesis and it is responsible for the storage of energy.

This is cellular respiration.

Sugar and oxygen are provided by eating and breathing.

How many moles are in 5.4x1024 molecules of C4H2F7I, heptafluoro-1-iodobutane? Group of answer choices

jasenka [17]

Given :

Number of molecules of $C_4H_2F_7I$ .

To Find :

How many moles are in given number of molecules.

Solution :

We know, in 1 moles of any element/compound contains $6.022\times 10^{23}$ at atoms/molecules.

So, number of moles in $5.4\times 10^{24}$ molecules are :

$n = \dfrac{5.4\times 10^{24}}{6.022\times 10^{23}}\\\\n = 8.97 \ moles$

Therefore, number of moles are 8.97 .

Most full scuba tanks have a pressure of between 1,800 p.s.i. and 3,000 p.s.i. (pounds per square inch). Approximately 70 to 85

ArbitrLikvidat [17]

Answer: The Diver's air tank is filled with oxygen gas.

The filling of air tank while keeping in water can be explained in reference to the Charles' Law.

Charles' Law: It states that the volume of the ideal gas is directly proportional to the absolute temperature at constant pressure.

$V\propto T$ (at constant Pressure)

The Scuba tank contains cold water and is present at high pressure. The gas which is put in the tank will be compact and would not expand. As the temperature is low inside the tank, hence by using Charles' Law, the volume will also decrease inside the tank.

When the air tank is filled, it is always kept in a tub of water because the pressure is high and hence, more oxygen gas can be filled inside the air tank.

mihalych1998 [28]

Answer:

The answer is C. The partial pressure of hydrogen will be unchanged.

Explanation:

$CO_{(g)} + 2H_{2(g)}$ ⇒ $CH_{3}OH$

Argon with electronic configuration $1s^{2}$ $2s^{2}$ $2p^{6}$ $3s^{2}$ $3p^{6}$ (that is atomic number 18) is an inert gas making it unreactive and it's addition to the reaction has no effect on the partial pressure of either the reactant or production or the state of the system.

The partial pressure of hydrogen will remain unchanged on the addition of Argon.
