Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.
The correct answer is cutting paper because it is an example of a physical change. A physical change is a change a change in the properties of matter that does not change the identity of the substance. On the other hand, chemical change is a change where the substance changes in identity after undergoing a process..
Make 2 in 102 as the power of 10
10^2 = 100
101 - 10^2 = 101 - 100 = 1
Hope it helped:)
Answer:
0.02 g/ml
Explanation:
si dividimos 10 con 500, es decir, 10/500, obtenemos 0.02. Las unidades serán g / ml.
Yes you can use that 1 equation.. P1V1/(n1T1) = P2V2/(n2T2) for ALL of your two state ideal gas law type problems. Use it in place of boyles, charles, avogadros, combined, etc laws...just like I showed you above
<span>(1).. write down P1V1/(n1T1) = P2V2/(n2T2) </span>
<span>(2).. rearrange for your desired unknown </span>
<span>(3).. determine what is constant and what varies.. cancel the constants </span>
<span>(4).. plug and chug.. don't forget Temperature must be on an absolute scale.. R or K.. never °F nor °C </span>
