This compound is named potassium chloride. Example 5: Write the name of the following formula: Na2S. First symbol is Na, so the first part of the name is sodium. (Note the presence of the subscript does not play a role in this name.) Second element is sulfur (from the symbol S), so the name is sulf + ide = sulfide. This compound is named sodium sulfide.
The viviparous sharks who carry the eggs until the pups are born, have different gestation periods. The dogfish shark is known to keep their eggs for 18 to 24 months. The bull shark gestation is about one year. The hammerhead shark gestation period is from 7 to 12 months. Other species that are ovoviviparous carry the eggs until the pups born alive and fully developed. They also have long gestation periods. The tiger shark gestation is about 14 to 16 months.
What is the gestation period for robins eggs? 14 days seems to be the correct answer. I have watched the Robins build their nest starting April 5, and I am watching them feed the babies today May 4th. Our Osprey's at Osprey House Environmental centre in Dohles Rocks Queensland Australia, laid an egg on the 22nd and a second on the 25th May 2009 with one egg still acti â¦ ve. We have been told that gestation is between 38 and 40 days, so here is hoping that we have a chick late June or early July.
