Answer: H2 + 2Ag+ -> 2Ag + 2H+
Explanation:
H2 + Ag+ -> Ag + H+
Oxidation half reaction: H2 -> H+
H2 -> 2H+ + 2e-
Reduction half reaction: Ag+ -> Ag
Ag+ + e -> Ag
Balance the numbers of electrons in each half equations
H2 -> 2H+ + 2e- x1
Ag+ + e- -> Ag x2
H2 -> 2H+ + 2e-
2Ag+ + 2e- -> 2Ag
Combine both half equations
H2 + 2Ag+ + 2e- -> 2Ag + 2H+ + 2e-
Canceling out the equal number of electrons on both sides
H2 + 2Ag+ -> 2Ag + 2H+
Answer:Cognitive dissonance refers to a situation involving conflicting attitudes, beliefs or behaviors. ... For example, when people smoke (behavior) and they know that smoking causes cancer (cognition), they are in a state of cognitive dissonance.
The answer will be A since chemical where discovered
Explanation:
The fundamental particles in an atom are protons, neutrons and electrons. The given atoms are called the isotopes of magnesium. They only differ in the number of neutrons they possess.
Protons are the positively charge particles in an atom
Neutrons occupy the center of an atom with protons and they carry no charges
Electrons orbits an atom and they carry no charges.
For a neutral atom, the number of protons and electrons are the same.
Magnesium - 24
Magnesium - 25
Magnesium - 26
Magnesium is an atom on the periodic table with an atomic number of 12.
The atomic number is the number of protons in an atom.
The numbers in front of the problem given are the mass numbers.
For neutral atoms;
Number of protons = number of electrons = atomic number
Number of neutrons = Mass number - atomic number
Magnesium - 24
Protons = 12
Electrons = 12
Neutrons = 24 - 12 = 12
Magnesium - 25
Protons = 12
Electrons = 12
Neutrons = 25-12 = 13
Magnesium - 26
Protons = 12
Electrons = 12
Neutrons = 26 - 12 = 14
