1st ionizaton energy has a trend from down to up and from left to right. Since Na and Al are on the same period (row), then the we look at which is the the furthest to the right and that would be Al.
Hi! i’m really really sorry but i’m answering to get pts. i tried to answer and I hope i’m right, I think A is 784. And B is 294. I’m in 5th grade btw
Answer:
A theory changes based on new observations and testing.
Explanation:
A scientific theory is a product of multiple trials and repeated experiments. It usually follows after carefully conducting and testing the validity of the hypothesis.
A scientific theory provides an explanation into how something behaves.
A law just states a finding will not explain it.
Most theories are tenable and can be improved upon when new observations and testing are carried out.
You multiply the mass by the acceleration 82*7.5=615; that's what I would do
1) The type of heat transfer is radiation (ie the sun's rays)
2) Not entirely sure what you mean but it is possible with this equation: KE = 3/2kT with k being the Boltzmann's Constant and T the temperature in Kelvins
3) True? Not really a question.
4) This would be emissivity
5) Thermal Energy
6) Celsius
7) A thermometer
