Answer: Ta is Tantalum, Os is Osmium and Rh is Rhodium
Explanation: All of these elements are in the transition metal group. Ta is part of the early transition metals while Os and Rh belongs to the late transition metals.
The molar mass of the unknown compound is calculated as follows
let the unknown gas be represented by letter Y
Rate of C2F4/ rate of Y = sqrt of molar mass of gas Y/ molar mass of C2F4
= (4.6 x10^-6/ 5.8 x10^-6) = sqrt of Y/ 100
remove the square root sign by squaring in both side
(4.6 x 10^-6 / 5.8 x10^-6)^2 = Y/100
= 0.629 =Y/100
multiply both side by 100
Y= 62.9 is the molar mass of unknown gas
Answer:
False, on the celsius scale it is -273.15°
Explanation:
[Ne] 3s² 3p⁴
Not sure if that’s right
1. B. Y is not a liquid, liquids don't fill the volume of their containers.
2. All four answers are honestly bad answers, but the most suitable one would be A. If you calculate the density yellow has a density of 5 and black has a density of 6.
3. C.
