1 answer:
Gre4nikov [31]3 years ago
6 0

Answer:

Dalton's 5 postulates

All matter consists of indivisible particles called atoms.

Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements.

Atoms cannot be created or destroyed.

Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

Describe differences between conduction and convection give examples
nevsk [136]

Explanation:

Both conduction and convection are both forms of heat transfer from one place to another.

  • In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
  • Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
  • Heat transfer in conduction is quite slow compared to convection which is much faster.

Example of conduction is heating of iron pot when cooking

Example of convection is the refrigerating system.

Define the following: Bronsted-Lowry acid - Lewis acid- Strong acid - (5 points) Problem 6: Consider the following acid base rea
Allushta [10]

Answer: Yes, HCl is a strong acid.

acid = HCl , conjugate base = Cl^- , base = H_2O, conjugate acid = H_3O^+

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

Yes HCl is a strong acid as it completely dissociates in water to give H^+ ions.

HCl\rightarrow H^++Cl^-

For the given chemical equation:

HCl+H_2O\rightarrow H_3O^-+Cl^-

Here, HCl is loosing a proton, thus it is considered as an acid and after losing a proton, it forms Cl^- which is a conjugate base.

And, H_2O is gaining a proton, thus it is considered as a base and after gaining a proton, it forms H_3O^+ which is a conjugate acid.

Thus acid =  HCl

conjugate base = Cl^-

base = H_2O

conjugate acid = H_3O^+.
