The ion N³⁻ is called the azide ion. In its neutral state, it occurs as the element Nitrogen. The atomic number of Nitrogen is 7. When it turns into an anion (negatively charged ion), it gains 3 more electrons. That's why its net charge becomes -3. It means that the protons is still 7, but the electrons are now 10.
Overall charge = +7 + -10 = -3
Is there any choices or is this a fill in the blank question?
Answer:
Option-B (water) is the correct answer.
Explanation:
Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.
Generally Gas hydrates have two main applications.
a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor.
b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.
4?
Explanation:
i think its 4, i might be wrong.
342 gm sugar = 1 mol of sugar = 12 moles of C. Therefore 25 gm of sugar will form = 25x12/342 = 0.877 moles of C. Therefore number of carbon atoms = number of moles x 6.02x 10^23 = 0.877x 6.02x 10^23 = 5.28x10^23.
