Answer:
in the ground near the poles hope that helps
If you are asking for the electron configuration of Ne, then the naswer is 2-8.
Answer:
A There are more particles in the air for water vapor to cluster around.
Explanation:
- As the condensation process takes place more particles are added to the atmosphere for water vapour and condensation further leads to the build-up of clouds.
- If the sky is polluted with pollutants the condensation can raise the level of pollution by blocking the rays of the sun from reaching the ground. This affects the visibility of most of the cities.
<u>Given:</u>
Volume of HCl (VHCl) = 25,0 ml = 0.025 L
Volume of NaOH (VNaOH) = 22.15 ml = 0.02215 L
Molarity of NaOH (MNaOH) = 0.155 M
<u>To determine:</u>
Molarity of HCl
<u>Explanation:</u>
Titration reaction-
HCl + NaOH → NaCl + H2O
Based on the reaction stoichiometry:
1 mole NaOH requires 1 mole HCl
# moles of NaOH = VNaOH * MNaOH = 0.02215*0.155 = 0.003433 moles
# moles of HCl = # moles of NaOH = 0.003433 moles
Molarity of NaOH = 0.003433/0.025 = 0.137 M
Answer to this is Radioactive isotopes.
Isotopes are the species of the same element having different atomic masses that means the number of protons remains the same but number of neutrons do differ. For example
and
are the two isotopes of Hydrogen (
).
Radioactive isotopes are the isotopes which release some kind of energy in the form of alpha particles, beta particles or gamma radiation. Examples of each of the decay processes are :
Alpha Decay: In this decay one alpha particle having atomic mass 4 and atomic number 2 or we can say a He molecule will come out. ![_{Z}^{A}\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_{2}^{4}\alpha](https://tex.z-dn.net/?f=_%7BZ%7D%5E%7BA%7D%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-2%7D%5E%7BA-4%7D%5Ctextrm%7BY%7D%2B_%7B2%7D%5E%7B4%7D%5Calpha)
Beta Decay: In this decay a
particle is emitted increasing the atomic number of the reactant by 1 unit.
![_{Z}^{A}\textrm{X}\rightarrow _{Z+1}^{A}\textrm{Y}+_{-1}^{0}\beta](https://tex.z-dn.net/?f=_%7BZ%7D%5E%7BA%7D%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ%2B1%7D%5E%7BA%7D%5Ctextrm%7BY%7D%2B_%7B-1%7D%5E%7B0%7D%5Cbeta)
Gamma Radiation: In this type of reaction only radiation is emitted out which does not change the original molecule.
![_{Z}^{A}\textrm{X}\rightarrow _{Z}^{A}\textrm{X}+\gamma\text{ radiation}](https://tex.z-dn.net/?f=_%7BZ%7D%5E%7BA%7D%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ%7D%5E%7BA%7D%5Ctextrm%7BX%7D%2B%5Cgamma%5Ctext%7B%20radiation%7D)
