Why was machine manufacture of horn combs often unsuccessful? - Answer Pieces of horn were not flat or uniform in thickness. Why weren't daguerreotype cases made from horn or horn powders? - Answer Horn does not flow easily and consequently it does not pick up fine details in a mold Casein comes from - Answer Milk curd Moderately nitrated nitrocellulose is called - Answer Pyroxylin What is the difference between collodion and moderately nitrated nitrocellulose? - Answer Collodion i...

AQA A Level Chemistry 2022 Paper 2 SOLUTION 2023//2024 How can we make polymers more flexible? - ANSWER By adding a plasticiser How do plasticisers make polymers more flexible? - ANSWER They stick between the chains and keep the polymers further apart from each other, weakening the van der Waals forces and lets chains slide more easily.
