It's a rock, so yes it's pretty hard; harder than talc, but softer than diamond - it's comes in between 3 and 4 on Mohs Scale.
Extra Credit
The Mohs scale was developed in France in 1812, hardness is a relative measure - on the Mohs scale one sample is considered to be harder than another if it can scratch it.
- Talc
- Gypsum
- Calcite
- Fluorite
- Apatite
- Feldspar
- Quartz
- Topaz
- Corundum
- Diamond
For an absolute measure of hardness you can use a Sclerometer which measures the depth of the scratch made by a diamond dragged across the surface of the sample under controlled conditions.
Limestone is a relatively strong and durable natural stone that is commonly used in construction and landscaping. Its strength can vary depending on factors such as the type of limestone, its porosity, and how it has been cut and prepared for use. Overall, limestone is known for its durability and ability to withstand a range of environmental conditions.
No, far from it. Limestone is actually quite soft, rating only a 3 or 4 on the Mohs scale.
Care should be taken when making generalisations about rock properties.
Hardness is a function of a material's elastic modulus (how much it deforms under a given load).
Limestone (like all rocks) is a natural Earth material. As such it can display a very large variability in properties.
For example limestones can have Young's modulus values ranging from 9 to 70 MPa.[A] This is clearly very variable, but the upper bound values are comparable with values derived for "hard" rocks such as metamorphic hornfels and the coarser grained igneous rocks such as granite, whereas the lower bound values are very soft indeed by rock standards.
So to answer the question, no, limestone is not the hardest rock, however some types of limestone can be classed with some of the hardest rocks, whereas other types may be some of the softest.

Limestone is a very strong rock and is used for the constructions of buildings and even some skyscrapers.
No. The weakest Rock in the world is most likely the shale rock, as it isn't really a solid rock and has a lot of layers (plates) of rocks, therefore making it weak.

What happens when acid reacts with limestone?
When acid reacts with limestone, a chemical reaction occurs where the acid dissolves the calcium carbonate in the limestone, forming water, carbon dioxide, and a calcium salt. This reaction is known as neutralization and can result in the limestone dissolving or fizzing as the carbon dioxide gas is released.
How did the rate of loss of the limestone change from the beginning of the experiment to the end?
The rate of loss of limestone increased as the experiment progressed. Initially, the reaction between the acid and limestone was slower, resulting in a lower rate of loss. However, as more limestone was consumed and the surface area for the reaction increased, the rate of loss of limestone accelerated.
What is the mass of 0.0249 L of limestone?
The mass of limestone will depend on its density. The average density of limestone is around 2.71 grams per cubic centimeter. You can calculate the mass by multiplying the volume (0.0249 L) by the density. Therefore, the mass of 0.0249 L of limestone would be approximately 0.0675 kg.
Calcium carbonate is a type of hydrogenous sediment that can be buried and hardened into .?
Calcium oxide.
Would rust damage limestone?
Yes, rust can potentially damage limestone if it comes into contact with it. The iron oxide in rust can cause staining, discoloration, and deterioration of the limestone surface over time. It's important to prevent rust from contacting limestone to maintain its appearance and integrity.
Is limestone rock strong?
no
Why is there Limestone in tooth paste?
For strong an healthy teeth
Can limestone be scratched?
yes it can because it is not such a strong sort of rock
What are the advantages of using limestone for building material?
There are a few advantages to using limestone for building materials. Limestone is pretty and elegant looking. Limestone is also a strong material to work with. Limestone takes very little maintenance and is fairly inexpensive.
How does limestone and sandstone smell?
Limestone typically does not have a noticeable smell. Sandstone may have a mineral-like smell due to its composition, but it is generally not strong or distinct.
Does carbonic acid cause the dissolution of limestone?
Yes, carbonic acid dissolves limestone as does any other acid. As carbonic acid is not a very strong acid this process is very sluggish, though.
How is Limestone affected by wind?
Wind can erode or abrade the surface of limestone through a process known as wind erosion. Over time, strong winds carrying abrasive particles can wear down the surface of limestone rocks, smoothing or shaping them. This process can lead to the formation of unique landforms like limestone hoodoos or arches.
Is limestone used is buildings?
Yes, because it is impermeable. Meaning water will not pass through it. It is also very strong and durable.
What happens when acid reacts with limestone?
When acid reacts with limestone, a chemical reaction occurs where the acid dissolves the calcium carbonate in the limestone, forming water, carbon dioxide, and a calcium salt. This reaction is known as neutralization and can result in the limestone dissolving or fizzing as the carbon dioxide gas is released.
How limestone is useful in toothpaste?
Limestone is used in toothpaste as a mild abrasive agent to help remove plaque and stains from teeth. It also helps to polish teeth and improve the appearance of the teeth. Additionally, limestone contributes to the overall texture and consistency of the toothpaste.
How is concrete formed from limestone?
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
What is limestone cave formed of?
Limestone and limestone formations.
