What is observed when water is added to a mixture of zinc carbonate and zinc chloride?
i know but i can’t tell u
What else can I help you with?
Why effervescence is observed when hydrochloric acid is added to a broken stalagmite?
Effervescence is observed when hydrochloric acid is added to a broken stalagmite made of calcium carbonate because the acid reacts with the calcium carbonate to produce carbon dioxide gas. This gas is released in the form of bubbles, creating the fizzing or effervescence effect.
Why more hydrochloric acid is added to sodium chloride in converting a carbonate to a chloride?
The carbonate ion is the conjugate base of a diprotic acid. If you react an equal number of moles of hydrochloric acid and sodium carbonate, the carbonate will only be partially neutralized you will get a mixture of sodium chloride and sodium bicarbonate. HCl + Na2CO3 --> NaHCO3 + NaCl Only by adding twice as many moles of HCl will you completely neutralize the sodium carbonate. 2HCl + Na2CO3 --> 2NaCl + H2O + CO2
Why did the mixture of magnesium carbonate and hydrocloric acid stop fizzing when more was added?
When more magnesium carbonate is added to hydrochloric acid and the fizzing stops, it could mean that all the acid has reacted with the magnesium carbonate to form magnesium chloride, carbon dioxide, and water. This reaction consumes the acid, causing the fizzing to cease.
Assume you had a mixture of solid na2co3 and nacl could you use only h2so4 to determine whether or not na2co3 was present explain?
Yes, you could use H2SO4 to determine the presence of Na2CO3 in the mixture. When H2SO4 is added to the mixture, effervescence will be observed due to the reaction between Na2CO3 and H2SO4, producing CO2 gas. This effervescence confirms the presence of Na2CO3 in the mixture.
When magnesium carbonate is added to dilute hydrochloric acid what salt does it form?
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
Why does the mixture stop fizzing when magnesium carbonate is added to hydrochloric acid?
When magnesium carbonate is added to hydrochloric acid, a chemical reaction occurs that produces magnesium chloride, water, and carbon dioxide gas. The fizzing you see is the carbon dioxide gas being released. Once all the carbon dioxide has been produced and released, the fizzing stops.
What happens when you add calcium chloride to potassium carbonate?
When you add calcium chloride to potassium carbonate the products will be solid calcium carbonate and aqueous potassium chloride. The chemical equation for this reaction is CaCl2(aq) + K2CO3(aq) --> 2KCl(aq) + CaCO3(s). This type of reaction is called a double replacement/displacement reaction.
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Calcium chloride is added to sodium chloride in the metallurgy of sodium because it helps lower the melting point of the mixture, making it easier to separate sodium metal from the molten mixture. This lower melting point allows for better efficiency in the electrolysis process.
What will be formed when 15 percent of hdrochloric acid is added to calcium carbonate?
When 15 percent hydrochloric acid is added to calcium carbonate, calcium chloride, carbon dioxide, and water will be formed. This is due to a chemical reaction where the acid reacts with the calcium carbonate to produce these products.
What happens when 2 ml of HCL is added to sodium carbonate?
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
Is season salt a mixture?
Yes it is. Plain salt is just sodium chloride. Seasoned salt has other flavourings added - making it a mixture.
