Which metal reacts quickly with cold water only when it is finely powdered?
Sodium is a metal that reacts quickly with cold water only when it is finely powdered. When the surface area of the sodium is increased by grinding it into a fine powder, it can react with the water at a faster rate due to the increased contact between the metal and the water molecules.
What role does carbon dioxide play when breaking down limestone?
Carbon dioxide reacts with water to form carbonic acid, which can dissolve limestone over time. This process is known as carbonation and results in the breakdown of limestone through chemical weathering.
What reacts with water to dissolve rocks such as marble and limestone?
Carbon dioxide reacts with water to form carbonic acid, which then reacts with minerals in rocks like marble and limestone, causing them to dissolve. This is known as carbonation weathering and is a common process in the dissolution of carbonate rocks.
Powdered mg reacts morre rapidly than strip of mg?
Powdered magnesium has a greater surface area compared to a strip of magnesium, which allows for more contact with the reactant, such as oxygen from the air. This increased surface area results in a faster reaction rate, as more magnesium atoms are available to react at the same time.
Why lakes with limestone beds experience less adverse affects from acid rain than lakes with granite beds?
Limestone is a basic rock that can neutralize acid rain, whereas granite is an acidic rock that can make bodies of water more susceptible to acidification. When acid rain reacts with limestone, it forms less harmful compounds than when it reacts with granite. This difference in buffering capacity helps lakes with limestone beds to experience less adverse effects from acid rain.
What is the process when powdered limestone reacts with the acid in the lake?
o
Processwhen powered limestone reacts with acid in lakes?
exothermic process takes place when powdered limestone reacts with acid in lakes.
What reacts with powdered sugar?
potassium permanganate reacts with powdered sugar
Name the process that takes place when the powdered limestone reacts with the acid in the lake?
it is a neautralisation reaction. i just got that exact same question in my AQA science workbook > <
What is the gas produced when limestone reacts with acid?
When limestone reacts with acid, Carbon Dioxide is produced.
It it the quartz in limestone which chemically reacts with HCl?
Limestone
Why powdered zinc reacts to form hydrogen gas faster than large pieces of zinc when both are placed in hydrochloric acid?
Powdered zinc has a larger surface area compared to large pieces, allowing for a higher rate of reaction with the hydrochloric acid. The increased surface area exposes more zinc atoms to the acid, leading to faster hydrogen gas production.
Which metal reacts quickly with cold water only when it is finely powdered?
Sodium is a metal that reacts quickly with cold water only when it is finely powdered. When the surface area of the sodium is increased by grinding it into a fine powder, it can react with the water at a faster rate due to the increased contact between the metal and the water molecules.
What rocks reacts with an acid?
Limestone
Why powdered flour reacts more quickly than lumps of wheats?
Powdered flour reacts more quickly than lumps of wheat because it has more surface area to absorb liquid.
Which rock decays faster from acid rain?
Limestone tends to decay faster from acid rain compared to granite. This is because limestone is composed mainly of calcium carbonate, which easily reacts with the acid in rainwater. Granite, on the other hand, contains minerals that are more resistant to acidic corrosion.
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.
