A significant contribution to atmospheric Carbon dioxide levels comes from the thermal decomposition of limestone in the manufacture of cement and of lime for agricultural purposes.

Cement works roast 1000 million tonnes of limestone per year and a further 200 million tonnnes is roasted in kilns to make lime.

What is the total annual mass output of carbon dioxide (in million tonnes) from these two processes?

In Raman spectroscopy, when we look at the spectra of some molecules there's always some line that do not appear, could you please tell me why is that?
thank you.

Study the effects of acids and bases on the tensile strength of fibre.

how does ethanoic acid, citric acid and sulphamic acid remove limescale from a coffee machine need a scientific explantion please

Give one example of acidic flux and basic flux

Sir,
Please help in some questions.
1. if we remove one proton and electron from an atom than that proton and electron become hydrogen atom as hydrogen atom contain only one proton. 2. Number of proton is equal to number of electron in an atom than why some atom contain different amount of electrons. 3. what is unstable atom. 4. why c-12 taken as standard mass in place of hydrogen. Hydrogen has one unit mass. So why hydrogen should not be used as standard mass
