Importance of Nitrogen to living things
What is Amino Acids,DNA,RNA,and Protiens?,($100)
100
wants to lose/gain electrons,charge becomes + or -,and the protons never change
What is an ion?($100)
100
a tower of elements,the number of valence electrons for the elements in that tower
What is a group?($100)
100
energy due to motion,E=m*v squared,object's mass and speed(velocity)
What is kinetic energy?($100)
100
the largest source of energy for the earth,(99%)
What is the sun?($100)
200
How clear the water is.
What is Transparency?($200)
200
neutrons are gained or lost,the mass changes,and the protons don't
What is an isotope?($200)
200
a bridge of elements,how many energy levels/rings an element has in that bridge
What is a period?($200)
200
energy that is due to gravitational forces between objects,E=m*g*h,g=9.8,h= meters
What is gravitational potential energy?($200)
200
energy can not be created from nothing or be completely destroyed,only transferred from one form to another.
What is the first law of thermodynamics?($200)
300
sediment,soil,algae,pollution,fertilizer,dung
What is factors that can affect transparency?,($300)
300
average mass of all the isotopes of that element
What is the atomic mass?($300)
300
surrounds the nucleus,valence
What is double jeopardy?(electron cloud),($600)
300
energy that is due to the energy stored in bonds,energy can be released when bonds are broken
What is chemical potential energy?($300)
300
when energy becomes less and less useful,most of it is lost as thermal energy(heat),you cannot make something from nothing
What is the second law of thermodynamics?($300)
400
