Answer:
17
Explanation:
the mass number of the element which is protons and neutrons is 17+18=35
electronic configuration is 2, 8, 7
valency of the element is 1 therefore the atomic number is 17
Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
The action force is you sitting on the chair and the reaction force is the gravity on the chair that is caused by you sitting on the chair
Mixing of pure orbitals having nearly equal energy to form equal number of completely new orbitals is said to be hybridization.
For the compound, the electronic configuration of the atoms, carbon and hydrogen are:
Carbon (atomic number=6): In ground state=
In excited state:
Hydrogen (atomic number=1):
All the bonds in the compound is single bond(-bond) that is they are formed by head on collision of the orbitals.
The structure of the compound is shown in the image.
The Carbon-Hydrogen bond is formed by overlapping of s-orbital of hydrogen to p-orbital of carbon.
In order to complete the octet the required number of electrons for carbon is 4 and for hydrogen is 1. So, the electron in of hydrogen will overlap to the 2p^{3}-orbital of carbon.
Thus, the hybridization of Hydrogen is -hybridization and the hybridization of Carbon is -hybridization.
The hybridization of each atom is shown in the image.
