Answer:
New volume is 14.35 mL
Explanation:
When a system of a gas keeps on constant its temperature and number of moles, the pressure is modified indirectly proportional to the volume:
Pressure increased → Volume decreased
Pressure decreased → Volume increased.
The relation you have to apply is: P₁ . V₁ = P₂. V₂
1.23 atm . 35 mL = 3 atm . V₂
(1.23 atm . 35 mL / 3 atm) = V₂
V₂ = 14.35 mL
Compare the density of the object in question to the density of water. If its density is less than water, it will float. For example, oak floats because its density is 0.7 g/cm³. If the density of an object is greater than water, it will sink.
Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.
The ionization constant equation is:
=1.0 × 
at 25°C
the option is 1.
Explanation:
Sometimes in pure water one proton of the water molecule(hydrogen ion) will get attracted to the lone pairs present in another water molecule.This causes the hydrogen ion to leave the present water(leaving the 
behind) molecule ad gets attached to another water molecule leading to the formation of the hydronium ion(
,hydronium ion).
This process is called auto-ionization of water because the water molecule ionizes into 
and ions.

As such the equilibrium constant,which is measure of concentration of products to concentration of reactants,will be very slow.
∴the ionization constant of water at 25°C is 1.0 × .
