Determining if an object will float or sink is based on the density of the object and also the density of the solution, the lower the density, more likely the object is to float, and if the density is higher, therefore the object is heavier and it will sink. In our question we have ebony wood with a density of 1.2, the only possible layer that this material can float is on Chloroform, that has a higher density, therefore the answer is letter A
It allowed him to realize that the mass of an atom is concentrated at its center because the atoms mostly went through the foil but some were deflected. He also realized that an atom probably wasn't just empty space and scattered electron and it had a positive center.
Answer:
C.) More NO₂ and SO₂ would form
Explanation:
Equilibrium:
This is the state of reaction in which the rate of forward reaction and reverse reaction are same.
There are three factors that effect the equilibrium condition.
The change in concentration
The change in volume
The change in temperature
In given equilibrium reaction,
SO₂ + NO₂ ⇄ NO + SO₃ + heat
when SO₃ is added it means more amount of product is on right side and equilibrium is disturb. Thus equilibrium is shifted toward the left produced more SO₂ and NO₂ and regain the equilibrium.
