Answer:
DISADVANTAGES OF ELECTRONIC COMMUNICATION
The cost of development: Electronic communication requires huge investment for infrastructural development. Frequent change in technology also demands further investment. Legal status: Data or information, if faxed, may be distorted and will cause zero value in the eye of law.
Answer:
Opposite poles of attract each other and make bonds.
Explanation:
Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.
Mass of Pd = 95.78 g which is close the the variant E) 95.89
Explanation:
To calculate the number of moles of palladium (Pd) we use the following formula:
number of moles = mass / atomic weight
mass = number of moles × atomic weight
mass of Pd = 0.90 × 106.42
mass of Pd = 95.78 g

Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!
Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!
