Carbon Dioxide has two polar C=O. bonds, but the geometry of Carbon dioxide is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.
I hope this helps :)
Answer:
0.26 mol
Explanation:
using general gas equation
PV=nRT
V=4.1litre= 4.1 dm³
P= 1.78 atm
R= 0.0821

In Silver, the 4d orbitals will be completely filled. That
implies that it does not have two electrons in the 5s orbital. The electronic
configuration of Silver is :
Ag (47) = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1
4d^10
Answer: 4.52x10²⁴ atoms Li
Explanation: For 1 mole of Li it is equal to the Avogadro's Number.
Solution:
7.5 moles Li x 6.022x10²³ atoms Li/ 1 mole Li
= 4.52x10²⁴ atoms Li
Answer:
Atoms is the smallest unit of a chemical element and consist of three main components protons, neutrons, and electrons.
The number of a neutron is based on the difference between the mass number of the atom (M) and the atomic number (Z). every isotope of an element has a different number of neutron.
But in a neutral atom or average atom, the number of neutrons is equal to the number of protons and the number of electron.
Example of the number of neutrons in an average atom: In Nitrogen-14, the atomic number and the number of protons is 7, it means the number of neutrons will also 7.
