Answer:
The atoms are ranked in decreasing order as follows:
Fluorine ---4
Carbon ----3
Boron ------2
Beryllium --1
Explanation:
Effective nuclear charge (Zeff) is defined as the difference between the actual nuclear charge (the atomic number, Z) and the shielding constant (S).
It is calculated by finding the atomic number and electronic configuration, attributing a shielding value to each electron, adding all the shielding values and using the formula:
Z eff = Z - S
Effective nuclear charges:
An atom of carbon: 3.25
An atom of fluorine: 5.20
An atom of beryllium: 1.95
An atom of boron: 2.60
C2H6 (g) + O2 (g). --> CO2(g)+H2O (g)
2C2H6 (g) + 7O2 (g). --> 4CO2(g)+6H2O (g)
(8.45 x 10^23)/(6.022x10^23) = 1.403 moles H2O
1.403 moles H2O x (4molCO2/6molH2O)= .935 moles CO2
.935 moles CO2 x (6.022 x10^23)= 5.63 x 10^23 molecules CO2
Answer:
Explanation:
Oxidation In chemistry is the gain in oxygen, loss of hydrogen and loss of electrons. Oxidation occur when an element with gain oxygen, loss hydrogen or loss electrons, which means the element is oxidized. Compared to reduction which is loss ofoxygen, gain of hydrogen and gain of electrons.
From the the question , Ag( silver) is undergoing oxidation.
Answer:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. Scientific and technological innovations mean that we are improving our efficiency at using and harvesting natural resources.
