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:
What is energy transformation? One type of energy can change into another type of energy. Energy transformation means the changing of energy from one type to another, e.g. from kinetic energy to electrical energy, or from potential energy to kinetic energy.
Explanation:
Physical properties define the appearance of that substance.
Answer:
12.4 × 10∧3 atoms
Explanation:
Given data:
moles of oxygen molecule= 1.0000 x 10-20 mol
atoms =?
Solution:
32 g O2 = 1 mol = 6.02 × 10∧23
1.0000 x 10∧-20 mol × 6.02 × 10∧23 × 2 = 12.4 × 10∧3 atoms
Answer:
A small amount of solute dissolved in a larger amount of solvent.
Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.
