The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. when a voltage of
76.2
v
is put across the plates of such a capacitor an electric field strength of
2.2
kv
cm
is measured.
write an equation that will let you calculate the distance
d
between the plates. your equation should contain only symbols. be sure you define each symbol.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
