Answer:
Similar
Explanation:
Elements that are located in the same vertical colomn or group of the periodic table have similar chemical properties. This is because they have the same amount of valence electrons in the outermost shell.
Answer:
The given statement is false.
Explanation:
Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.
The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.

Explanation:</h3>
<u>Step 1: Define</u>
[RxN] 2AgNO₃ + BaCl₂ → 2AgCl + Ba(NO₃)₂
[Given] 5.0 g AgNO₃
<u>Step 2: Identify Conversions</u>
[Reaction - Stoich] 2AgNO₃ → 2AgCl
Molar Mass of Ag - 107.87 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of AgNO₃ - 107.87 + 14.01 + 3(16.00) = 169.88 g/mol
Molar Mass of AgCl - 107.87 + 35.45 = 143.32 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:

- Multiply/Divide:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 1 sig fig.</em>
4.21533 g AgCl ≈ 4 g AgCl
The question above is simply asking us to convert the value from calories into kilojoules. Therefore, we need some factor to multiply to be able to convert it to such units. For calories to kJ, the factor would be 4.184.
2700 cal ( 4.184 kJ/cal) = 11296.8 kJ
