Answer:
See explanation
Explanation:
The reaction to be considered is shown below;
H2CO3<------->CO2 + H2O
We know that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.
Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.
Answer:
C

Explanation:
The given reaction is synthesis reaction in which lithium and bromine react to form lithium bromide.
Chemical equation:
Li + Br₂ → LiBr
Balanced chemical equation:
2Li + Br₂ → 2LiBr
Step 1:
Li + Br₂ → LiBr
left hand side Right hand side
Li = 1 Li = 1
Br = 2 Br = 1
Step 2:
Li + Br₂ → 2LiBr
left hand side Right hand side
Li = 1 Li = 2
Br = 2 Br = 2
Step 3:
2Li + Br₂ → 2LiBr
left hand side Right hand side
Li = 2 Li = 2
Br = 2 Br = 2
Answer:
2HNO3 +Na2CO3 → CO2 + H2O + 2NaNO3
Answer:
Distance cover by school bus = 149.5 miles
Explanation:
Given:
Velocity of school bus = 65 mph
Time taken by school bus = 2.3 hours
Find:
Distance cover by school bus
Computation:
Distance cover = Velocity x Time taken
Distance cover by school bus = Velocity of school bus x Time taken by school bus
Distance cover by school bus = 65 x 2.3
Distance cover by school bus = 149.5 miles
