What is the slovent and the solute of a 10-karat bracelet?
The answer depends on what other metals are in the alloy.
How can new information be added to science?
scientist make observations and evaluate they data to find new information
When sodium carbonate solution is added to benzocaine what is the gas that evolves?
Because the reaction mixture contains a small amount of sulfuric acid, the sodium bicarbonate will neutralize the solution and in the process, will produce CO2.
What is general test for protein?
1. Add 5 cm3 dilute sodium hydroxide (caustic!) to a 1% solution of albumen (the white part of an egg)2. Then add 1% copper sulphate solution3. A purple colour appears and this indicates that protein is present.
How do you dilute a concentrated solution?
It really depends on what type of solution you are dealing with. However by definition any solution that is less pure or takes up a smaller perecentage of the whole is diluted. Anything that will make the total amount of solution you currently have become a smaller percentage of the whole. Ex: When you begin with solution A and have 100 mL it is 100%. If you mix in 100mL of solution B the total solution is now 200mL and it is 50% solution A and solution B. It is now diluted.
What gas is evolved when dilute nitric acid is added to Zinc?
When dilute nitric acid is added to zinc, the gas evolved is nitrogen dioxide (NO2) along with water and zinc nitrate.
What happen when dilute nitric acid is added to a sample of chalk?
Chalk is calcium carbonate (CaCO3) thus addition of dilute acid will produce carbon dioxide and a calcium salt. E.g. addition of dilute hydrochloric acid will produce CO2 and calcium chloride (CaCl2).
What happens when dilute sulfuric acid is added to magnesium carbonate?
MgSO4+ H2O + CO2
What happens to the atoms of copper when added dilute nitric acid is added?
(Cu)s + 2HNO3 --> Cu2+ + 2NO3- + (H2)gas
When magnesium carbonate is added to dilute hydrochloric acid what salt does it form?
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
What is the precipitate of dilute sulfuric acid added to copper 2 carbonate?
The precipitate formed when dilute sulfuric acid is added to copper(II) carbonate is copper(II) sulfate. The reaction can be represented as follows: CuCO3 + H2SO4 -> CuSO4 + H2O + CO2
What dilute acid is added to a sample of limestone the rock fizzes what chemical does the rock contain?
If the limestone rock fizzes when dilute acid is added, it indicates the presence of calcium carbonate in the rock. When calcium carbonate reacts with acid, it produces carbon dioxide gas, which causes the fizzing.
What chemical compound gives off gas when dilute hydrochloric acid is added to it?
You think probable to calcium carbonate.
Which gas is evolved when few pieces of marble is added to dilute HCl?
When marble (calcium carbonate, CaCO3) is added to dilute hydrochloric acid (HCl), carbon dioxide gas (CO2) is evolved due to the reaction between the acid and the carbonate compound. This gas can be observed as bubbles coming out of the solution.
How do you design an experiment to find out what happens when a carbonate is added to some dilute acid?
To design an experiment to investigate the reaction between a carbonate and a dilute acid, you would set up two identical containers with dilute acid. In one container, add the carbonate, and in the other, do not. Measure variables such as temperature change, gas production, or pH levels to determine the reaction outcomes. Compare the results between the two containers to analyze the effect of adding the carbonate to the dilute acid.
What would you observe before dilute acetic acid is added to calcium carbonate?
Before dilute acetic acid is added to calcium carbonate, you would observe that the calcium carbonate is a white solid. There may be no visible reaction or bubbling occurring prior to the addition of the acid.
What happens when Nitric acid is added to lead (II) carbonate by crystallisation?
When nitric acid is added to lead (II) carbonate, a double displacement reaction occurs. Lead (II) nitrate and carbonic acid are formed. However, carbonic acid is unstable and decomposes into carbon dioxide and water, leaving behind lead (II) nitrate as the final product.
