What else can I help you with?
Which carbonate mineral reacts readily with cool dilute hydrochloric acid to produce visible bubbles of carbon dioxide gas?
Any carbonate will fizz. Examples would be calcite, marble, limestone. They are all calcium carbonate.
Why would bubbles appear if an acid were poured on chalk?
Chalk is calcium carbonate, CaCO3 and acid contains H+. So, using HCl as an example of the acid being used, the chemical reaction would be CaCO3 + 2HCl ==> CaCl2 + CO2 + H2O and the bubbles are formed by the CO2 (carbon dioxide) gas being produced.
How many grams are in 2.8 moles of calcium carbonate?
2,8 moles of calcium carbonate have 240,208 g.
In a double displacement reaction between calcium nitrate and sodium carbonate the precipitate produced would be?
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
How would you separate water sodium carbonate and calcium carbonate?
To separate water, sodium carbonate, and calcium carbonate, you could first evaporate the water to leave behind the dry sodium carbonate and calcium carbonate. Next, you could use solubility differences to further separate the sodium carbonate and calcium carbonate; calcium carbonate is insoluble in water while sodium carbonate is soluble. So, you could dissolve the mixture in water, filter it to remove the calcium carbonate, and then evaporate the water to obtain the sodium carbonate.
What precipitate is produced by the reaction between calcium chloride and potassium carbonate?
The precipitate produced by the reaction between calcium chloride and potassium carbonate is calcium carbonate. When calcium chloride and potassium carbonate are mixed together, a double displacement reaction occurs, leading to the formation of calcium carbonate, which is insoluble and thus precipitates out of the solution.
When dilute hydrochloric acid is placed on the sedimentary rock limestone and the metamorphic rock marble bubbling reaction occurs with both What would this indicate?
The bubbling reaction indicates that both limestone and marble contain calcium carbonate. The hydrochloric acid reacts with the calcium carbonate to produce carbon dioxide gas, which is seen as bubbles. This is a common test to identify rocks containing calcium carbonate.
What metal is found in limescale?
Limescale is mostly calcium carbonate with some magnesium carbonate mixed in there as well. So the answer would be calcium.
Marbel chalk and limestone all contain a substance called calcium carbonate. explain what would happen if they were each put into some hydrochloric acid?
When marble, chalk, or limestone are placed into hydrochloric acid, a chemical reaction occurs which releases carbon dioxide gas. The calcium carbonate in these substances reacts with the hydrochloric acid to produce calcium chloride, water, and carbon dioxide. This reaction can be observed by the formation of bubbles as the carbon dioxide gas is released.
A mineral that contains calcium carbonate will provide a positive response to a test for .?
acid reaction
What is the minimum amount of calcium carbonate in a limestone rock?
Limestone is composed of at least 50% calcium carbonate (CaCO3) by weight. Therefore, the minimum amount of calcium carbonate in a limestone rock would be 50%.
Why would you choose calcium chloride for the reagent to precipitate the soluble carbonate?
Calcium chloride is chosen as a reagent to precipitate soluble carbonates because it forms insoluble calcium carbonate when reacted with a carbonate compound. The insoluble calcium carbonate precipitates out of the solution, allowing for the separation of the carbonate from the remaining solution.
