The mass of the liquid water will be greater because it takes more space and room. will ice cubes arnt liquid and can only take a little space of room.
Answer:
T₂ = 218.75 K
Explanation:
Given data:
Initial volume = 20 L
Initial pressure = 16 atm
Initial temperature = 500 K
Final temperature = ?
Final volume = 35 L
Final pressure = 4 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
by putting values,
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁/ P₁V₁
T₂ = 4 atm × 35 L × 500 K / 16 atm × 20 L
T₂ = 70000 atm .L. K / 320 atm.L
T₂ = 218.75 K

6)Po
7) Atomic size increases down the group
8) B<Al<Ga<In<Tl
9)Se<C<Ga
10) ionization energy is the energy required to remove electrons from the outermost shell of an atom.
Explanation:
In the periodic table, the properties of elements reoccur ''periodically'' throughout the table, hence the name 'periodic table'.
Ionization energy increases across the period hence the noble gas He has the highest ionization energy.
Since ionization energy increases across the period, group 1 elements possess the lowest ionization energy.
Since atomic size increases down the group and decreases across the period, gallium is smaller than indium, potassium is smaller than caesium, polonium is smaller than titanium and iodine is larger than bromine.
This explanation above justifies the order of increasing atomic radius of group 13 elements shown in answer number 8 above.
Since atomic size decreases across the period, the order of increasing atomic size shown in answer number 9 above is correct.
Ionization energy is the energy required to remove electrons from the outermost shell of an atom.
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 ×

Answer:
- <u><em>Both fitth electons are located on a 2p orbital.</em></u>
Explanation:
The electrons fill the orbitals of the atom in increasing order of energy level. Using Aufbau's mnemonic rule you can find the order of filling:
- 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ . . .
Thus, the firs two electrons are located on the 1s orbital, the next two electrons are on the 2s orbital, and the <em>the fifth, electron of </em>both <em>boron and carbon is located </em>on a 2p orbital.
