Answer:
A transition element atomic number 29 copper Cu
Explanation:
Answer:Figure 1. Energy losses in an incandescent light bulb are very large; most of the input energy is lost in the form of heat energy. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat. ...
Explanation:
A neutral atom has the same number of protons and electrons. Anytime an element has a charge, that means either more electrons or protons were added.
more electrons= negative charge
more protons = positive charge
Your charge is +3 which means there are 3 more protons than electrons
First answer is proton number is 21
The nucleon number means mass number which is protons + neutrons
24 + 21 = 45
Nucleon number is 45
Answer:
MgF
Explanation:
because it has the high percent of Ionic
Ka expression for any substance:
Ka = [H+] [A-] / [HA]
In this case,
Ka = [H+][C₃H₅O₃-]/[C₃H₆O₃]
1.4 x 10⁻⁴ = [H+] [C₃H₅O₃-] / [C₃H₆O₃]
pKa = -log(Ka)
pH = -log([H+])
The difference between pKa and pH is that pH is the negative logarithm of only the concentration of hydrogen ions, while pKa is the negative logarithm of the ratio of the product of the concentrations of hydrogen ions and concentration of base to the concentration of acid.
