It takes more energy to breakdown the bonds
Answer:
The innermost electron shell of an atom can hold up to _____ electrons. ... What determines the types of chemical reactions that an atom participates in? the number of electrons in the outermost electron shell. Atoms with the same number of protons but with different electrical charges
The molar mass of the following compounds in two decimal places are as follows:
- NH3: 17.04 g/mol
- Mg(OH)2: 58.33 g/mol
- Fe2O3: 159.70 g/mol
<h3>MOLAR MASS:</h3>
The molar mass of a compound is the sum of all the atomic masses of the elements that constitutes the compound.
According to this question, three compounds were given as follows: NH3, Mg(OH)2 and Fe2O3.
The atomic mass of the elements in this compounds are as follows:
- N = 14
- H = 1
- Mg = 24
- O = 16
- Fe = 56
- The molar mass of NH3 = 14 + 3 = 17g/mol
- The molar mass of Mg(OH)2 = 24 + 32 + 2 = 58g/mol
- The molar mass of Fe2O3 = 56(2) + 16(3) = 160g/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>
