Answer:
Are transferred completely from the valence shell of an element to the other
Explanation:
Basically, to form a chemical bond, you either transfer or you share. When you share, it is a case of covalent bonding which can be in several other forms. When there is a transfer, it is a case of ionic bonding.
The basic explanation for this is that while some atoms are electronically sufficient, some are electronically deficient. This means while some atoms are having an excess number of electrons, then some are having less number of electrons.
To satisfy both parties, there must be a transfer if electrons between the two parties. While the one with the excess numbers serves as the donor, the one with insufficient number of electrons serve as the acceptor
Average speed of the trip = 52 km/hr
<h3>Further explanation </h3>
Distance is the length traveled by an object within a certain of time .
Average speed = total distance/total amount of time ,
Can be formulated :
![\tt S(speed)=\dfrac{D}{T}](https://tex.z-dn.net/?f=%5Ctt%20S%28speed%29%3D%5Cdfrac%7BD%7D%7BT%7D)
Total distance travelled : 1560 km
Total time : 8 hr + 12 hr + 10 hr = 30 hr
![\tt avg.speed=\dfrac{tot~D}{tot~T}\\\\avg.speed=\dfrac{1560}{30}\\\\avg.speed=52~km/hr](https://tex.z-dn.net/?f=%5Ctt%20avg.speed%3D%5Cdfrac%7Btot~D%7D%7Btot~T%7D%5C%5C%5C%5Cavg.speed%3D%5Cdfrac%7B1560%7D%7B30%7D%5C%5C%5C%5Cavg.speed%3D52~km%2Fhr)
Answer:
1.23x10^-6 mole
Explanation:
A clear understanding of Avogadro's hypothesis proved that 1mole of any substance contains 6.02x10^23 atoms. This indicates that 1mole of Ag contains 6.02x10^23 atoms.
Now, 1f 1mole of Ag contains 6.02x10^23 atoms, then Xmol of Ag will contain 7.41x10^17 atoms i.e
Xmol of Ag = 7.41x10^17/6.02x10^23 = 1.23x10^-6 mole
