Ireally need ! no one has me! will give brainliest, , andif you are good at science and hurry ! how does the law of conservation of mass apply to this reaction: c2h4 + 3o2 --> 2h2o + 2co2? a. only the oxygen needs to be balanced b. the equation needs to be balanced. there are fewer oxygen atoms in the equation than hydrogen and carbon c. the law of conservation of mass has already been applied d. each element needs to be balanced

It is "c", and i hope it's correct. please pm me, if you need more help

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
