How were greenhouses heated before electricity?
the sun Not only were greenhouse heated from the engery produced by the sun but also by heat from paraffin heaters and heated water pipes heated by coal or wood fires.
How is limestone used in cement?
Limestone has greater strength and better bonding capacity.Limestome is crushed in to fine particles in the preparation of cementLimestone is the major constituent in cement of about 60-67%.
What is the formula for Ca2 plus and OH?
CaCO3 also known as limestone.
Why is limestone cooled in a dry argon atmosphere after being heated?
Limestone, when heated produces calcium oxide (CaO) and carbon dioxide (CO2). CaO is highly reactive and will combine with CO2 from the atmosphere to reverse the above process. It will also react with any water vapour in the atmosphere to form calcium hydroxide (CaOH). These reactions can be prevented by allowing the CaO to cool in an inert environment such as that provided by argon.

Why is limestone so important?
Limestone, quicklime and slaked lime are all used to neutralise excess acidity - which may be caused by acid rain - in lakes and in soils. Limestone is used as a building material, and to purify iron in blast furnaces. It's also used in the manufacture of glass, and of cement (one of the components of concrete). * Limestone (CaCO3) can be used as a '''building material''' and in the manufacturing of '''iron'''. * '''Glass''' - heated with sand and soda (sodium carbonate). * '''Cement''' - heated with clay in a kiln. ** Concrete - mixed with sand, water and crushed rock ** Mortar - mixed with sand and water * '''Quicklime''' - heated. ** Slaked lime (Calcium Hydroxide Ca(OH)2) - mixed with water *** Lime motar - mixed with water
What is the chemical formula of chalk?
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
How does limestone erode?
Limestone erodes with water. Limestone can also erode through water getting in to the cracks and then freezing. This causes the crack to expand and will begin to erode the limestone.
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 sedimentary rock is made underwater from the shells of animals?
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.
What is the parent rock of limestone?
Limestone doesn't normally have a parent rock. One exception to this may be a detrital limestone, whose parent rock would however also be limestone!
How does sulfuric acid react with limestone?
if limestone is in a solid form it would degrade (hence a loss in mass of the limestone) and carbon dioxide would be given off. if it is in the powdered form the change in mass would not be very obvious and only a loss carbon dioxide would be seen.
