Dung dịch NH3 đậm đặc có nồng độ 26 % (d = 0,904 g/ml). Dung dịch này có nồng độ mol/lít là bao nhiêu? Nếu lấy 100 ml dung dịch này để pha thành dung dịch NH3 1 N thì thể tích dung dịch sau khi pha loãng là bao nhiêu ml? (Đáp số:13,8 M; 1380 ml)

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

What is the subscript for oxygen in its molecular formula

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
