Answer:
5.77 g
Explanation:
Amount of calcium sulfide = 0.0800 mol
Molar mass of calcium sulfide = 72.1 g/mol
Mass of calcium sulfide = 0.0800 mol x 72.1 g/mol
= 5.77 g
Answer:
.001g/cm^3 are in 1kg/m^3
Explanation:
divide the mass / volume value by 1000
Chemical reactions are in equilibrium when there is no net change in the reactants or products.
Chemical equilibrium refers to the situation in a chemical reaction where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties. When the forward reaction and the reverse reaction go forward at the same speed, this condition results. The forward and backward reactions typically have equal, if not zero, reaction rates. As a result, the concentrations of the reactants and products do not fluctuate much, indicating that the chemical reaction is in equilibrium.

Molar mass:
CH₄ = 12 + 1 x 4 = 16.0 g/mol
CO₂ = 12 + 16 x 2 = 44.0 g/mol
Balanced <span>equation :
</span>
<span>CH</span>₄<span> + 2 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O
</span>
16.0 g CH₄ --------------- 44.0 g CO₂
(mass of CH₄) ----------- 46.4 g CO₂
mass of CH₄ = 46.4 x 16.0 / 44.0
mass of CH₄ = 742.4 / 44.0
= 16.87 g CH₄

Answer : The correct option is, (B) bimolecular
Explanation :
Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.
The given chemical reaction are,
Step (1) :
Step (2) :
Step (3) :
The number of reactants molecules taking part in the balanced equation of a reaction 2 are, .
In this reaction, 1 'I' molecules reacts with the 1 molecule.
Total number of reactant molecule = 1 + 1 = 2
The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.
Hence, the correct option is, (B) bimolecular
