Does paint contain limestone?
In paints, limestone is used as a filter extending expensive pigments. Limestone is calcium carbonate with the chemical formula of CaCO3.
How do you make k2cr2o4 solution?
It is prepared by roasting powdered chromite with potash and limestone, treating the cinder with a hot potassium sulfate solution and leaching.Alternatively, it may be prepared by the reaction of potassium dichromate and potassium hydroxide.
How does the humidity of air effect the type of snow that falls?
It soon then becomes powdered snow and sometimes makes sleet or hailstones too.
What are the pro and cons of limestone?
Limestone is good for making building materials:Glass - limestone + sand + sodium carbonate heated to about 1500degrees CCement - limestone + sand heated in a rotary kilnConcrete - cement (from limestone) + sand + water + gravelMortar - calcium hydroxide (slaked lime = Limestone that has thermally decomposed to calcium oxide (quicklime) and then had water added to it) + sand + waterAll of these make useful building materials. Powdered limestone or slaked lime (see above) are also both alkaline substances, so are often used in fertiliser to neutralise acidic soil.However, we have to consider where we will obtain limestone from. The quarrying of limestone can have damaging social and environmental factors, although it would have positive economic factors.Social - increased noise pollution, increased traffic, less clean airEnvironmental - pollution caused by increased trafficEconomic - more jobs in the areaThen we have to consider the impact of making glass, cement, concrete and mortar out of limestone. For example, glass production requires a lot of energy to create enough heat.
What is powdered limestone?
Powdered limestone is commonly referred to as lime, the result of crushing limestone rock.
Why is powdered limestone used in the chimneys at power stations?

o
What do you get when powdered quartz and powdered limestone are soda are mixed?
This looks to me like a recipe for making glass (you would have to melt them).

Why do the neutralising effects of powdered limestone on soil last longer than that of slaked lime?
no
How can you turn limestone to cement?
Powdered limestone has to be heated with powdered clay to turn it into to cement. You can then use cement and powder it, then mix with water, sand crushed rock and a slow reaction takes place forming concrete. It is in the Cors Science GCSE
What is the formula of whitewash?
Typically whitewash is powdered lime (lime as in limestone, not the green fruit!) mixed with water.
Why does powdered marble and powdered limestone have an identical reaction to hydrochloric acid?
Because chemically, both are mainly made from calcium carbonate.
Why is it safer to use powdered limestone instead of calcium hydroxide to neutralise acidic soil?
Because limestone is not dangerous when in contact with plants/animals etc. whereas I think calcium hydroxide is an irritant
