Any kind of pull or push is a force. In order to illustrate a force, one must be familiar with two things. One must be familiar with the direction of the force and the size of the force. The forces, which are equivalent in size but in opposite direction are known as the balanced forces.
The balanced forces do not result in a change in motion. When the balanced forces function on an object at rest, the object will not move. The forces, which results in a change in the motion of an object are known as the unbalanced forces. The unbalanced forces are not opposite and equal.
Answer:
V₂ = 1592.32 L
Explanation:
Given data:
Initial number of moles = 1.54 mol
Initial volume = 383.2 L
Final volume = ?
Final number of moles = 6.4 mol
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = initial number of moles
V₂ = Final volume
n₂ = Final number of moles
now we will put the values in formula.
V₁/n₁ = V₂/n₂
383.2 L / 1.54 mol = V₂/ 6.4 mol
V₂ = 248.8 L/mol ×6.4 mol
V₂ = 1592.32 L
The physical process of evaporation involves the heat absorbing and the status of the substance changing. The status of this substance changes form liquid to gas.
Answer:
cinnamic acid - 150 mg
cis-stilbene - 100 μL
trans- stilbene - 100 mg
pyridinium tribromide - 200-385 mg
For this data:
moles of cinnamic acid = 0.150 g/148.16 g/mol = 0.001 mols
Theoretical mass of dibromoproduct formed = 0.001 mol x 307.97 g/mol = 0.312 g
cis-stilbene (100 ul = 0.1 ml)
moles of cis-stilbene = 0.1 ml x 1.01 g/mol/180.25 g/mol = 0.00056 mols
Theoretical mass of dibromoproduct formed = 0.00056 mol x 340.05 g/mol = 0.19 g
trans-stilbene
moles of tran-stilbene = 0.1 g/180.25 g/mol = 0.00055 mols
Theoretical mass of dibromoproduct formed = 0.00055 mol x 340.05 g/mol = 0.19 g
