The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
Electrons = protons
protons = atomic number
protons + neutrons = atomic mass
Therefore: a) protons + 7 = 15
protons= 15 -7
protons= 8
B) Remember proton = atomic number
so atomic number = 8
C)Now we know the atomic number so we can easily check on the periodic table what element has an atomic number of 8, which is Oxygen
Answer:
c
the cycling of water in and out of the atmosphere
Answer:
CaO - inorganic
C₂H₄(OH)₂ - organic
Ca(OH)₂ - inorganic
CH₄ - organic
NaCl - inorganic
C₃H₈ - organic
Explanation:
Organic compounds have carbon (C) in it.
For example, CaO has calcium and oxygen, but no carbon so it's an inorganic compound. However, C₂H₄(OH)₂ does have carbon, making it an organic compound.
