Answer:
A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.
Explanation:
Answer:
B.) the role of the microscope world in creating new material.
Explanation:
Trust me boys and girls.
Answer:
strong base
Explanation:
because a element having pH of greater than 7 is a base and the color of the substance is purple
so it is a strong base
Answer:
State functions are Temperature, Enthalpy, Energy, Internal Energy and Adiabatic work.
Explanation:
a) State functions are those thermodynamic functions which depends only on the final and initial state of the system but not on the path followed.
From the given options only heat is not a state function.
b) (i) Reversible Process is the process which can be reversed at any point by making even very small changes in the properties of the system.
(ii) Enthalpy is defined as the total heat content of the system. It can also be written as the sum of internal energy and product of pressure and volume of the system.
(iii) Entropy defines the extent of randomness in any system.
So, a substance in gaseous state has more entropy than its liquid state as gaseous particles can more freely.
(iv) Internal Energy is the energy that involves both potential and kinetic energy of the system. It involves energy for all sorts of random motions of the particles.
(v) Isentropic processes are processes in which entropy remains constant or entropy change is zero during the process.
(vi) Adiabatic processes are those process in which there is no heat change in the process. For example in thermos flask, there is no exchange of heat between system and surroundings.
Answer:
Mole = 2.67
Given data:
Number of atoms of carbon = 1.61 × 10²⁴
Avogadro's Number = 6.023 × 10²³
Required:
Moles = ?
Solution:
Formula for calculating moles from particle numbers is given as,
Mole = Number of particle / Avogadro's number
putting values
Moles = 1.61 × 10²⁴ / 6.023 × 10²³
Moles = 2.67
