Answer:
The difference between the Thompson's plum pudding model and the Rutherford atom model is the location of the electrons (option a).
Explanation:
While Thompson compared his atom to a plum pudding, where the electrons floated freely in the pudding, Rutherford established the arrangement of the electrons in orbitals, which were found around the atomic nucleus like the planets around the sun.
Rutherford's findings also established the existence of a small, positively charged nucleus.
<em>Thompson and Rutherford models did not differentiate between the charges of electrons and protons
, overall charges or overall size of the atom.</em>
Answer:
<h2>The answer is 2.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>
Hope this helps you
POH will be -log[conc of OH]
-log (3.9E-08) = 7.409
pH = 14- pOH
pH = 14 - 7.409
pH = 6.59
When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy.
