Answer:
option C= A positive ion is attracted to negative ion
Explanation:
Ionic bond:
Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.
we know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.
But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.
For example:
Take the example of sodium that can lose one electron and form Na+. This Na+ ion is called cation because it carry positive charge by losing the one electron. This cation now contain eleven proton and ten electron.
Now consider the example of Chlorine atom. It consist of 17 proton and 17 electron. But in order to attain the noble gas configuration or to complete the octet it gain one electron and form anion (Cl-). The chlorine anion consist of 17 proton and 18 electron.
Now consider the sodium chloride which is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.
Answer:
For A = 733.2 torr
For B = 740.1 torr
Explanation:
Given data:
For A
Height = 15.4 mm
Pressure of atmosphere = 0.985 atm ( 0.985 ×760 = 748.6 mmHg)
Pressure of gas = ?
For B
Height = 12.3 mm
Pressure of atmosphere = 0.99 atm ( 0.99×760 = 752.4 mmHg)
Pressure of gas = ?
Solution:
For A
P( gas) = P (atmosphere) - 15.4 mmHg
P( gas) = 748.6 mmHg - 15.4 mmHg
P( gas) = 733.2 mmHg or 733.2 torr
For B
P( gas) = P (atmosphere) - 12.3 mmHg
P( gas) = 752.4 mmHg - 12.3 mmHg
P( gas) = 740.1 mmHg
or
740.1 torr
Answer: There are three main factors that characterize the Bohr model. First, in the Bohr Model, the orbits have a set size and energy. There’s a correlation between energy and size: the smaller the orbit, the less energy it has. Electrons can move from one orbit to another by emitting or absorbing radiation.
Explanation: Hope this helped !
<span>0.0157 L.
For this equation use the combined gas law, which states P1*V1/T1 = P2*V2/T2, but in this case we can remove the T, because T1 = T2, because the temperature is constant. Then we solve for V2 because it is the new volume. So
P1*V1/P2 =V2
Plug in the variables, P1 = 100 atm, V1 = 1.02 L, P2 = 65.0 atm, and V2 = 0.0157 atm.</span>
