Answer:
The dissociation constant for the acid ( experimental ) is 1.45 lit/mol
Explanation:
The value of dissociation constant can be calculated as,
= C × ∝²
Where, C = concentration of the solution = 0.329M
∝ = Degree of dissociation
again , Degree of dissociation can be obtained form :
= C × ∝
∝ =
∝ = = 7.072
So, now = C × ∝²
= 0.329 ×( 7.072)²
= 1.45 lit/ mol
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.

Answer:
C₂O₂
Explanation:
Step 1: Given data
- Molar mass of the molecular formula: 56 g/mol
Step 2: Calculate the molar mass of the empirical formula
M(CO) = 1 × M(C) + 1 × M(O) = 1 × 12 g/mol + 1 × 16 g/mol = 28 g/mol
Step 3: Calculate "n"
We will use the following expression.
n = molar mass of molecular formula / molar mass of empirical formula
n = (56 g/mol) / (28 g/mol) = 2
The molecular formula is:
CO × n = CO × 2 = C₂O₂
Answer:The reaction absorbs 8100 J of energy from the surroundings as it proceeds.
Explanation:
Answer:
Why do most atoms form chemical bonds? They want a full outer shell of electrons, so the lose, gain, or share electrons with other elements, forming compounds, until they have 8 valence electrons and become stable. Double and triple covalent bonds that have greater bond energy and are shorter than single bonds.
