In the lake that the rivers lead, water molecules evaporate into the sky and form clouds. In the sky, these water droplets condense and form clouds that will eventually rain.

The water evaporates and then, the clouds form condensation, because the gas becomes water, and falls as rain.

What happens when a gas reaches a cold surface and it changes into a liquid

Mademuasel [1]

To change phases, a substance either gains or looses energy. If a substance gains energy, it will become more exited and the molecules will spread out. An example of this is water boiling into gas. If it looses energy, the molecules will become less exited and come closer together. For example, freezing water takes away energy from molecules, changing it from liquid to solid

When a gas reaches a gold surface, it looses much of the energy that it had, so the gas condenses from gas to liquid phase.

Hope this helped!! :D

Where do the protons and electrons come from that are used in the electron transport chain?

blondinia [14]

The energy generated by the movement of electrons is used to pump electrons across the inner mitochondrial membrane to an area of higher concentration. 17. Where do these protons (H+) come from? The originally came from a glucose molecule and were carried to the electron transport chain by NADH and FADH2.

The answer would be glucose molecule.

Integrated rate law for second order unimolecular irreversible

kirill115 [55]

Answer:

The rate law for second order unimolecular irreversible reaction is

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

Explanation:

A second order unimolecular irreversible reaction is

2A → B

Thus the rate of the reaction is

$v = -\frac{1}{2}.\frac{d[A]}{dt} = k.[A]^{2}$

rearranging the ecuation

$-\frac{1}{2}.\frac{k}{dt} = \frac{[A]^{2}}{d[A]}$

Integrating between times 0 to t and between the concentrations of $[A]_{0}$ to [A].

$\int\limits^0_t -\frac{1}{2}.\frac{k}{dt} =\int\limits^A_{0} _A\frac{[A]^{2}}{d[A]}$

Solving the integral

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

Calculate the volume of 2.0116 x 10^23 molecules of nh3 gas trapped in a container at a pressure of 2280.0 mmhg and a temperatur

OLEGan [10]

The problem in this question can be solved using the ideal gas formula. Ideal gas formula show interaction between the pressure, volume, temperature and the number of molecules.

n= number of molecule/ avogadro number
n= (2.0116 x 10^23 / 6.02*10^23)= 1/3 mole

T= celcius + 273.15
T= (41+273.15) K=314.15

P=2280 mmHg / (760mmHg/atm)= 3 atm

PV=nRT
V= nrT/ P
V= 1/3 moles * (0.08205 L atm / mol·K) * 314.15 K / 3 atm
V= 2.864 L

To dissolve in water, aluminum (Al) should form a compound with

nadezda [96]

To dissolve in water, aluminum (Al) should form a compound with sulfate. Aluminum sulfate is the water soluble compound of aluminum. It has a chemical formula of Al2(SO4)3. It is used in industries as flocculating agent especially in the purification steps of drinking water and wastewater treatment plants.
