they try to ask themselves why certain things happen and they try to make an educated guess of what will happen.
Answer:
mass and distance
Explanation:
The strength of this force depends on the <u>mass</u>
of each object and
the <u>distance</u>
between them.
Answer:
0.51
Explanation:
Given the Nernst equation;
E= E° - 0.0592/n logQ
E= 355 mV or 0.355 V
E° = 0.34 - 0= 0.34 V
n= 2(two electrons were transferred in the process)
Equation of the reaction;
H2(g) + Cu^2+(aq) -----> 2H^+(aq) + Cu(s)
Substituting values;
0.355 = 0.34 - 0.0592/2 log([H^+]/1)
0.355 - 0.34 = - 0.0296 log [H^+]
0.015/-0.0296 = log [H^+]
Antilog (-0.5068) = [H^+]
[H^+] = 0.311 M
pH = -log[H^+]
pH= - log(0.311 M)
pH = 0.51
Protons are positively charged, electrons are negatively charged, and Neutrons have no charge or are in fact "neutral". Protons and Neutrons are located in the nucleus of an atom and are most of the atoms mass. Electrons have an extremely minute mass even compared to Protons and Neutrons
