Answer: As one atomic dipole nears another atom it will affect the electron density distribution, so for example if the slightly positive end of the atom is located next to another atom, it will attract the electron(s) in the other atom. A covalent bond happens when atoms share an electron between them. The other kind of bond is called ionic, and it happens when one atom gives an electron to another atom. These bonds are held together with electric forces. Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.
The balanced equation for the neutralisation reaction is as follows
Ca(OH)₂ + H₂SO₄ ---> CaSO₄ + 2H₂O
stoichiometry of Ca(OH)₂ to H₂SO₄ is 1:1
equivalent number of acid reacts with base
number of H₂SO₄ mol reacting - 2 mol
according to molar ratio of 1:1
number of Ca(OH)₂ mol = number of H₂SO₄ moles
therefore number of Ca(OH)₂ moles required - 2 mol
Answer:
mountains
Explanation:
A mountain can be defined as a land-form that has characteristics of high elevation and high relief. Mountains rise above the land and rise to form a peak. It is because of the high elevations that the climates are cooler in the mountainous regions as compared to the sea level. The mountains are elevated, have relief, and have steepness and continuity.
Answer:
The molecular weight is
Explanation:
From the question we are told that
The mass of the sample is
The temperature is
The volume which the gas occupied is
The pressure is
Generally from the ideal gas equation we have that
Here n is the number of moles of the gas while the R is the gas constant with value
=>
=>
Generally the molecular weight is mathematically represented as
=>
=>
