Which of the following is a displacement reaction a caco3 Cao co2 B Cuo h2 Cu h2o C C o2 co2 D Fe CuSO4 FeSO4 CU?
Fe + CuSO4→ FeSO4 + Cu is an example of displacement reaction. As iron is a more reactive metal displaces copper from its salt solution.
What is the chemical equation for glucose?
C₆H₁₂O₆Glucose / Formula
What is the chemical reaction for oxidation of glucose?
C6H12O6 +6O2 ⟶6CO2+6H2O+Energy (ATP)
What is the word equation for sulfuric acid?
H2SO4 (l) H2O (g) + SO3 (g).
Which of the following is a displacement reaction CaCO3 s → CaO’s )+ CO2 g?
Answer: Explanation: Decomposition: A substance breaks down to smaller species. [e.g. CaCO3(s) → CaO(s) + CO2(g) Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating.]
Which of the following is displacement reaction CaO h20?
In the reaction between calcium and water to form calcium hydroxide and hydrogen, calcium displaces hydrogen from water. Thus, this is a displacement reaction.
What is the word equation for acid and carbonate?
Acid + Metal Carbonate → Metal Salt + Carbon Dioxide + Water.
Which salt is formed when CaCO3 reacts with sulfuric acid?
CaSO4
Sulfuric acid reacts with the free lime (CaCO3) which is insoluble in water. The reaction between sulfuric acid and lime to form gypsum takes minutes. H2SO4 + CaCO3 (lime) = CaSO4 (gypsum).
What is the equation for anaerobic respiration GCSE?
Glucose → Lactic Acid + Water Anaerobic respiration can also take place in yeast, where glucose is broken down to create ethanol, carbon dioxide and energy.
What is the chemical equation for aerobic respiration?
The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done.
What happens when Na2CO3 reacts with H2SO4?
Na 2 CO 3 + H 2 SO 4 → Na 2 SO 4 + CO 2 + H 2 O [ Check the balance ] Sodium carbonate react with sulfuric acid to produce sodium sulfate, carbon dioxide and water. Sulfuric acid – diluted solution.
What are some examples of anaerobic respiration?
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid.
What happens when sodium carbonate react with sulfuric acid?
Sodium carbonate react with sulfuric acid to produce sodium sulfate, carbon dioxide and water. Sulfuric acid – diluted solution. If playback doesn’t begin shortly, try restarting your device.
