The effusion rate of H2 molecules is 4.342 times that of an unknown gas. Determine the molar mass of the unknown gas. You can write the formula for Graham's law of diffusion or effusion of gases as: rate 1 / rate 2 = √ (mass 2 / mass 1) , where: rate 1 and rate 2 - Rates of effusion or diffusion of Gas 1 and 2, respectively, measured moles per unit time

<h3>What is H2 molecules?</h3>

The chemical element hydrogen is represented by the letter H and atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas made up of diatomic molecules with the formula H2. It is non-toxic, tasteless, colorless, odorless, and extremely flammable. In the cosmos, hydrogen is the most prevalent chemical, making up around 75% of all ordinary matter. [note 1] Plasma hydrogen makes up the majority of stars like the Sun. On Earth, hydrogen mostly takes the form of molecules like water and organic substances. Each atom of hydrogen's most prevalent isotope, 1H, has one proton, one electron, and no neutrons.

Hey there!:

is the solution <span>saturated  , ie :

</span>They are the ones that have reached the exact solubility coefficient.<span>If we mix 64.4 g of KCl at 200.0 g of water at 20 º C, we'll see that the 32.2 g will dissolve and the remainder (32.2 g) will precipitate, forming the bottom body. In this case we will then have a solution saturated with background. However, if we want only the saturated solution, simply perform a simple filtration to separate the precipitate from the saturated solution.

hope this helps!</span>

kirza4 [7]

Answer: a) Cu\rightarrow Cu^{2+}+2e^-  : anode

b. 2H^++2e^-\rightarrow H_2 : cathode

c. O^{2-}\rightarrow \frac{1}{2}O_2+2e^-:  anode

Explanation:

Electrochemical cell is a device which converts chemical energy into electrical energy. It consist of two electrodes, anode and cathode.

Oxidation i.e. loss of electrons , which results in an increase in oxidation number occurs over anode.

Reduction i.e. gain of electrons, which results in decrease in oxidation number occurs over cathode.

a. Cu\rightarrow Cu^{2+}+2e^-  : oxidation :  anode

b. 2H^++2e^-\rightarrow H_2 : reduction : cathode

c. O^{2-}\rightarrow \frac{1}{2}O_2+2e^-: oxidation : anode

Which statement best describes the relationship between photosynthesis and cellular respiration?
Elena L [17]

Answer:

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

The first option clearly expresses the relationship between photosynthesis and cellular respiration.

Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.

In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.
