Answer:
2 unpaired electrons
Explanation:
Carbon's bonding state electron configuration is 1s2 2s1 2s1 2p1 2p1. So, there are 4 unpaired electrons in the orbitals of carbon in bonding state.
hope this helps
Answer: (C) 30 times
Richter scale is used to determine the magnitude of an earthquake from the arrival time of P and S waves. It determines the total amount of energy released during an earthquake.
If Richter magnitude scale measures 6.5 then it produces 30 times more energy than 1 Richter scale magnitude during an earthquake. The magnitude of an earthquake is plotted on a logarithmic scale from 1 to 9 and increases 10 folds by one magnitude. If 6.5 is the magnitude, it means it is 10 times more than 5.5 magnitude earthquake. Similarly the amount of energy is calculated as 30 folds. So 6.5 magnitude will have 30 folds more energy released than that with 5.5 magnitude earthquake.
It will have metal in it . The other would not. It’s actually very simple
