Re: Physical state of acids when they are ionized « Reply #3 on: August 11, 2014, 02:28:29 AM » HCl is a gas at STP, to make it liquid you need either low temp (boiling point around -85 °C) or high pressure. But even then it is hardly an acid, as HCl molecule is...
Mass is a measure of the amount of matter in an object. The amount of space an object takes up is described by its volume. The density of an object depends on its mass and its volume. For example, the water in a drinking glass has the same density as the water in the same volume ...
A solution state interaction between silicic acid, Mg2+ and Al3+ released from Neusilin US2 and indomethacin was determined to be the mechanism behind the higher apparent solubility of co-ground amorphous indomethacin. Thus an enhancement in solubility is NOT solely due to amorphization or partial ...
Ab Initio and Dynamics Study of the O(P-3) + NH3 and O(P-3) + N2H4 Reactions at Hyperthermal Collision Energies The reactions between ground-state oxygen atoms (O((3)P)) and the ammonia (NH(3)) and hydrazine (N(2)H(4)) molecules have been studied using electronic-structure and ...

CD studies suggest that sulfane sulfurtransferase has a significantly higher proportion of α-helix than rhodanese. The renaturation of sulfane sulfurtransferase denatured in 6 M guanidine was shown to be rapid and complete provided that the enzyme had not been oxidized while in the denatured state. ...
The 603 provides a three-state coherency protocol that supports the exclusive, modified, and invalid cache states. This protocol is a compatible subset of the MESI (modified/exclusive/shared/invalid) four-state protocol and operates coherently in systems that contain four-state caches. The 603 ...
The physical method is to crush the raw materials mechanically, but the chemical composition basically does not change, and the physical method mainly includes mechanical ball milling; chemical reduction method is to obtain powder by changing the chemical composition or aggregation state of raw ...
I suspect we need to worry about this rather less than we are: most children are very good at identifying changes of state. They do it instinctively. They only start getting confused about it when we teach them a lot of rules which they then try to apply. I’m pretty sure that’s no...
