Hence 2.107 x 10^23 atoms are present in 41.7 g of tin(Sn).
Mass of 2.37 x 10^22 atoms of Xe is 5.12031 g.
Hope this helps, have a great day/night ahead!
Answer: What is the three-dimensional shape of the molecule with this Lewis structure?
Explanation: CO2 Molecular Geometry and Lewis Structure Molecular Geometry which is also known as Molecular Structure is the three-dimensional construction or organization of particles in a molecule.
Answer:
The sole purpose is to rejuvenate the column. After long use the ions bound in the permutit column will get washed away. This can be replaced by washing the column with NaCl.
Answer:
Sun
Explanation:
The closest star from the Earth is the sun.
Explanation:
total heat = Heat required to convert 2 kg of ice to 2 kg of water at 0 °C + Heat required to convert 2 kg of water at 0 °C to 2 kg of water at 20 °C.
Heat=mhfg+mCpΔT
Here, m ( mass of ice) = 2 kg
hfg (latent heat of fusion of ice) = 334 KJ
Cp of water (specific heat) = 4.187 KJ/Kg-K
ΔT(Temperature difference) = 20 °C
Therefore, Heat required = 2 x 334 + 2 x 4.187 x (20 - 0 )
Heat reqd= 835.48 KJ
Therefore, to melt 2 kg of ice 835.48 KJ of heat is required.
