Calculate the mass, in grams, of a single xenon atom (mxe = 131.29 amu ).

Mariana [72]

Answer is $2.18017\times10^{-22}gms$ .

Explanation: To calculate the mass of 1 Xe-atom , we will require atomic mass of Xe which is 131.29amu.

This atomic mass is the mass of 1 mole of 1 Xe-atom. One mole of Xe-atom is $6.022\times10^{23}$ atoms of Xe. We will use this relation to convert Mass of Xe-atom into grams.

$\frac{\text{mass of 1 atom}}{atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}atoms}$

$\text{mass of 1 atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}}$

$\text{mass of 1 Xe-atom}=\frac{131.29}{6.022\times10^{23}}$

$\text{mass of 1-Xe atom}=21.8017\times10^{-23}gms$

= $2.18017\times10^{-22}gms$

olga_2 [115]

Answer:

Solvent

Explanation:

Many people use the solute to describe the solid being dissolved and the solvent to describe the thing doing the dissolving, but really solvent means the part of the solution with a greater amount/concentration.

For example, if you have 1 gram of salt in 10 liters of water, the water is the solvent.

Which equation represents a redox reaction?

labwork [276]

Answer:

D. $2NaBr + Cl_2\rightarrow 2NaCl + Br_2$

Explanation:

Hello!

In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:

Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:

$2NaBr + Cl_2\rightarrow 2NaCl + Br_2$

$Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow Br_2^0+2e^-$

Unlike the other reactions whereas no change in the oxidation states is evidenced.
