Convert the following temperatures from degrees Celsius to degrees Kelvin: 0 degrees C, 30 degrees C, 100 degrees C.

Conversion from degree Celsius to Kelvin :

1.

0° C = 0 + 273.15 = 273.15 K

2.

30 ° C = 30 + 273.15 = 303.15 K

3.

100° C = 100 + 273.15 = 373.15 K

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
