Compounds characteristics differ in some cases significantly, from those of the constituent elements. This is due to the fact that when elements in a compound combine, a whole new substance with distinct features results.

A specific chemical composition will always consist of the same elements inside the exact same mass quantities, according to the law of fixed proportions.

Although they may have different appearances, elements and compounds have many things in common, such as being composed of atoms and possessing bonds that connect their atoms. Additionally, both elements but also compounds share the characteristics of being pure as well as homogeneous entities.

Rhenium has two naturally occurring isotopes Re - 185 with a natural abundance of 37 40%, and Re - 187 with a natural abundance

Leya [2.2K]

Answer:

individual isotopes

Re 185 = 139.094

Re 187 = 232.815

Explanation:Correcting the typo error for natural abundance as 37 40 as 37.40 and 62 60 as 62.60

Answer is found as follows

For Re 185 natural abundance 37.40%

371.9087 x 37.40/100 = 139.0938538

six significant figures after rounding off = 139.094

For Re 187 natural abundance 62.60

371.9087 x 62.60/100 = 232.8148462

six significant figures after rounding off = 232.815

A 6.35 l sample of carbon monoxide is collected at 55.0◦c and 0.892 atm. What volume will the gas occupy at 1.05 atm and 59.0◦c?

Sonja [21]

Answer : The final volume of gas will be, 5.46 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 0.892 atm

$P_2$ = final pressure of gas = 1.05 atm

$V_1$ = initial volume of gas = 6.35 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $55.0^oC=273+55.0=328K$

$T_2$ = final temperature of gas = $59.0^oC=273+59.0=332K$

Now put all the given values in the above equation, we get:

$\frac{0.892atm\times 6.35L}{328K}=\frac{1.05atm\times V_2}{332K}$

$V_2=5.46L$

Thus, the final volume of gas will be, 5.46 L
