AI Thread Summary

Heating lanthanum hydroxide La(OH)3 from 20°C to 900°C in an oxygen-rich environment leads to its dehydration, resulting in the loss of water molecules. As a result, the mass of La(OH)3 decreases rather than increases. The process transforms La(OH)3 into lanthanum oxide (La2O3) through the removal of water. Therefore, the mass does not increase due to the release of water vapor during heating. Understanding this reaction is crucial for applications involving lanthanum compounds.

Hey guys!, I just want to know what will happen when you heat up lanthanum hydroxide La(OH)3 from 20 degree Celsius to 900 degree Celsius in a furnace with O2 gas. Is the mas of La(OH)3 increases? and why? thanks in advance!

No. It dehydrates.

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
