This can be explained by the periodic trend that atomic size decreases from left to right in a given period. This is due to the effective nuclear charge increase, or how much more the nucleus pulls in on the electrons. Therefore Sodium (Na) has the largest atomic radius.
Answer : The mass of 7.0 m chain is, 15.12 kg
Explanation :
As we are given that,
The weight of the chain per unit length = 2.16 kg/m
Now we have to determine the mass of chain for 7.0 m length.
As, the mass of 1 m length of chain = 2.16 kg
So, the mass of 7.0 m length of chain =
= 15.12 kg
Therefore, the mass of 7.0 m chain is, 15.12 kg
Answer:
electrical
Explanation:
they are working together
Answer:
If it takes more energy to break the original bonds than is released when the new bonds are formed, then the net energy of the reaction is negative. This means that energy must be pumped into the system to keep the reaction going. Such reactions are known as endothermic.
