Still confused... I am still not so understand. In a situation where the temperature of liquid is 60oc, and the boiling point of that liquid is 120oC. Can I concluded that the temperature is a pure liquid (not vapor exist)? So as long as the temperature of the liquid is below the boiling point...

metal will react with water in some situation, that is corrosion. Its the ionic reaction between metal, water and air. but the reaction is so slow, may be years. Generally, metal can consider does not react with water.

In the figure that shows saturated vapor and liquid condition under varying temperature and specific volume (constant temperature), there are 2 lines, 1 is saturated liquid line, the other is saturated vapor line. so the region in between these 2 lines is called the mixture of saturated liquid...

Has anybody heard of this code, ASTM D394-47(B)? I can only find ASTM D394-59(1965) and it as already withdrawn at 1969. Thank you!

I solved for the heat of neutralization already, I thought, but now, I got the final temperature after reaction is 121.75 oC which I think is too big. I start with initial pH = 2 and final the conc H+ = 10^-(pH=2) then I find the mole by multipling the conc with the tank volume (400m3), the I...

Confused I would like to know the answer too. But from my previous calculation, I got 32.20 oC (If using del_H(96%) - del_H(infinite)), and 25.08 oC (If using del_H (96%) - del_H(10%)). From this website "[URL ,[/URL] the answer is 33.70 oC. And I even run a test myself, and the temperature...

Source The heat of solution you can get it from Perry's Chemical Handbook or Elementary Principles of Chemical Process.

according to the rules in physics forum, we can't help those that didnt show their efforts. We are just guiding, not doing all the homework for you. you must at least show your way of calculations before we can help you.

1 more question I solve the dilution of NaOH already. Thank you Bystander. 1 more question to ask, is this method suitable for all types of dilution? Like if I want dilute 96% sulphuric acid to 30% sulphuric acid? But I can't get a similar answer to what I got from this website...

confused The Cp Value I used is 20% not 50%. About the del Hsoln, I didnt use del H 20% - del H 50% but instead, I used del H 20% - del H infinite, like what i learn from the book Elementary Principles of Chemical Process. Does this cause a difference? By the way, why you use this ratio...

i mean what's the product if I mix these two things together...

What I actually looking for is, do anybody have any data or tables or figures about the normal flux that run through the sand filter...
