HELPPPP MEEE PLEASEEE!!!!!!
MrRa [10]
Mass =70 ( Mass of protons=1 ,Mass of neutrons =1, Mass of electron =0.0005(can be ignored))
Therefore, 40 +30=70
Charge= -2 ( it is taking in/attracting electrons to its shell) base on the proton number you are able to identify if it is attracting or releasing an electron, if the electron number is more than proton number then it is attracting therefore resulting in a negative charge vice versa for releasing an electron.

Which equation can be used to convert from Celsius to Kelvin? O Celsius + 459.67 O (Celsius)x1.8+32 O (Celsius-32)x5/9 Celsius+2
Kaylis [27]

Answer:

Celsius +273.15

Explanation:

The two scales have the same size degree, but Kelvin is an absolute scale based on absolute zero while 0° in Celsius is based on the melting point of water. So, in order to convert from Celsius degrees to Kelvin we only need to add 273.15 to the given temperature:

K= °C + 273.15
