1. the noble gas krypton (Kr).
Answer:
The temperature at which rhenium becomes superconducting is -271.6 ºC.
Explanation:
We can convert the temperature given in Kelvin, which is an absolute scale, into degrees Celsius. which is a relative scale, by a simple algebraic translation, that is:
(1)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in Kelvins.
If we know that
, then the temperature given in degrees Celsius is:


The temperature at which rhenium becomes superconducting is -271.6 ºC.
Answer:
C + 2H2 ⇒ CH4
Explanation:
In order to balance a chemical equation you need to make sure that the number of atoms on both sides are equal
C + H2 = CH4
C = 1
H = 2
Products:
C = 1
H = 4
H2 = 2 × 2 = 4
C + 2H2 ⇒ CH4
Hope this helps.
