Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.
Calcium carbonate has a formula CaCOз. Explain what this formula means?
Calcium carbonate has a formula CaCOз. Explain what this formula means?Anwer :CaCO3 means that for each molecule of it, it has one atom of Calcium, one atom of Carbon and 3 atoms of Oxygen.
How do chemists explain this difference?
Chemists explain differences in properties or behavior by looking at the molecular structure of substances. Variation in molecular structure can lead to differences in physical, chemical, and biological properties. By understanding how atoms are arranged and interact within molecules, chemists can explain why substances exhibit different characteristics.
What is the word used to explain the behaviour of matter and mixtures?
The word used to explain the behavior of matter and mixtures is "chemistry." Chemistry is the branch of science that studies the composition, structure, properties, and reactions of matter. It explores how substances interact, combine, and transform.

Where are written laws displayed in public places?
Two examples are in offices and factories (to explain certain health and safety laws) and in railway stations (to explain the terms and conditions of carriage).
Explain what happens to rainwater on the coral island?
the rain water is soaked up and held underground in the porous limestone floating on top of salt water.
In your own words explain how a stalactite forms?
Most stalactites are limestone. Water, often rainwater, seeps through material which causes it to absorb carbon dioxide, as it seeps further it dissolves limestone. Then when it reaches the ceiling of a cave it slowly begins to forms droplets. As these dry they deposit the limestone on the ceiling. This happens again and again, one drop at a time, and very slowly over years this deposit grows forming a stalactite.
On your raid ant double control ant killer we do not understand direction separate bait stations from plastic frame Explain what you mean please?
There are several bait stations (little boxes) attached to the plastic frame. You have to pull them all off the frame so you can spread them around.

A stone roof is supported by collumns made up of limestone why might this be unsafe after a fire in a building explain the chemical process involved in the weakening of the structure?
Limestone is CaCO3. Let us decompose it:CaCO3 ---> CaO + CO2Heating the limestone will cause the above reaction to take place and replace the relatively firm structure of the limestone rock with a more powdery structure of the CaO. Another example might be this:Mg + (1/2)O2 ---> MgOThe relatively hard structure of the magnesium metal is replaced by a powdery MgO and the MgO structure falls apart into a heap of MgO dust.Source(s):ChemTeam
What would weather faster exposed limestone in southern Florida or exposed granite in northern Canada Explain?
Exposed limestone in southern Florida would weather faster than exposed granite in northern Canada due to several factors. Limestone is more susceptible to chemical weathering, particularly from acidic rain and humidity, which are prevalent in Florida's subtropical climate. In contrast, granite is a harder igneous rock that weathers more slowly, and the colder climate of northern Canada can limit the effects of physical weathering processes. Thus, the combination of limestone's composition and Florida's warm, humid conditions accelerates its weathering compared to granite in a cooler environment.
Is 'Falling Up' a Christian band?
Yes. They are. In all of their interviews (you can see on YouTube) they talk about how all of their songs are coming from God. They explain how and why. They are my favorite band personally. And they come on christian stations all the time. So yes. They are.
