Is calcium hydroxide soluble?noslightlyyesQuestion 2 of 10 Loading... 3. What is meant by the term viscosity?The viscosity of a fluid describes how easily it flows. Water has a low viscosity, it flows very easily. Crude oil has a higher viscosity than water, it does not flow very easily.The viscosity of a fluid is how easily it evaporates.

What is an ore?A rock (compound) which metal can be extracted from.A piece of glassware used for distillationA measuring device used to find the density of rocksAn unreactive element used as a carrier for displacement reactionsQuestion 4 of 10 Loading... 5. Give two reasons why addition polymers are hard to dispose ofThey are inert as they have strong C-C bonds. This makes them biodegradeable. Also, they produce toxic gases when burned.They are inert as they have weak C-C bonds. This makes them biodegradeable. Also, they produce toxic gases when burned.They are inert as they have strong C-C bonds. This makes them non-biodegradeable. Also, they produce toxic gases when burned.They are inert as they have weak C-C bonds. This makes them non-biodegradeable. Also, they produce toxic gases when burned.Question 5 of 10 Loading... 6.
