Answer:
an aqueous species is the answer
Answer:
0.50 mol
Explanation:
The half-life is <em>the time required for the amount of a radioactive isotope to decay to half that amount</em>.
Initially, there are 8.0 moles.
- After 1 half-life, there remain 1/2 × 8.0 mol = 4.0 mol.
- After 2 half-lives, there remain 1/2 × 4.0 mol = 2.0 mol.
- After 3 half-lives, there remain 1/2 × 2.0 mol = 1.0 mol.
- After 4 half-lives, there remain 1/2 × 1.0 mol = 0.50 mol.
Answer:
The correct option are:
1. (b) current
2. (c) potential
3. (b) coulombs (C)
4. (a) amperes (A)
5. (d) volts (V)
Explanation:
Electric charge is a property of a particle, like electron and proton. The subatomic particles, electrons and protons are negatively and positively charged particles, respectively.
The electric charge of a particle can be measured in <em>coulomb, denoted by C</em>.
Current or electric current is defined as the <em><u>net flow of the electric charges through a given region, per unit time.</u></em> Electric current can be measured in <em>ampere, denoted by A.</em>
<em>Potential or Electric potential</em> is described as the work done to displace the electric charges from one point to another. <em><u>Potential is the driving force for the movement of charges</u></em> and can be calculated in <em>volt, denoted by V.</em>
