The answer is B. As the element X is from group two. This means two electrons can be lost. However nitrogen is from group 5 . You need three more electrons to fill the electron shell. Therefore, you need to find the LCM of 2and 3,which is six. 6over 2 is 3 . Which means you need three element X
Answer:
Cost = 165.6 cents = $1.656
Explanation:
First, we will calculate the total energy consumed by the bulb in a month:
where,
E = Energy Consumed = ?
P = power = 23 W
t = time = (1 month)(30 days/1 month)(24 h/1 day) = 720 h
Therefore,
Now, the cost will be:
<u>Cost = 165.6 cents = $1.656</u>
