What determines the strength of an arrhenius base? give one example each of an aqueous solution of a strong base and an aqueous
IceJOKER [234]
The strength of an Arrhenius base determines percentage of ionization of base and the number of OH⁻ ions formed. 
Strong base completely ionize in water and gives a lot of hydroxide ions (OH⁻), for example sodium hydroxide: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Weak  base partially ionize in water and gives a few hydroxide ions (OH⁻), for example ammonia: NH₃ + H₂O(l) ⇄ NH₄⁺(aq) + OH⁻(aq).

The temperature and number of moles of a gas are held constant. Which of the following is true for the pressure of the gas?
Taya2010 [7]

Answer:

Pressure is inversely proportional to the volume of gas.

Explanation:

According to Boyle's law,

The volume of given amount of gas is inversely proportional to the pressure applied on gas at constant volume and number of moles of gas.

Mathematical expression:

P ∝ 1/ V

P = K/V

PV = K

when volume is changed from V1 to V2 and pressure from P1 to P2 then expression will be.

P1V1 = K         P2V2 = K

P1V1 = P2V2

<h2>Complete the table to summarize the properties of the different subatomic particles. </h2>

Explanation:

Atom

It is a smallest particle which cant exist independently.

According To Dalton, atom was indivisible but later on, it was proved that atom can be subdivided into sub atomic particles called electron, proton & neutron.

These subatomic particles have marked properties .

Proton

  • It is positively charged particle
  • It is present in nucleus .
  • Its mass is equal to 1.6726219 × 10⁻²⁷ kilograms

Neutron

  • It was discovered by E.chadwick .
  • It is neutral
  • It is present inside the nucleus .
  • It's mass is equal to 1.674927471×10⁻²⁷ kg

Electron

  • It was discovered by J.J Thomson .
  • It has negative charge .
  • It's mass is equal to 9.10938356 × 10⁻³¹ kilograms
  • It is present outside the nucleus in shells .
