The lead carbonate is dissolved in nitric acid and carbon dioxide is released.
1) effervescence (Ignore carbon dioxide)
2)lead (II) carbonate disappears
3)colorless solution formed
Lead + nitric acid -------> lead nitrate + hydrogen
it will dissolve
The answer depends on what other metals are in the alloy.
scientist make observations and evaluate they data to find new information
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.
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.
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.

MgSO4+ H2O + CO2
(Cu)s + 2HNO3 --> Cu2+ + 2NO3- + (H2)gas
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).
2hcl- + k2co3====>2h2co3+2kcl
You think probable to calcium carbonate.
you are suppose to start with your success criteria
H+ +hco3 -> h2o + co2
Thre will be a reaction resulting in the formation of Calcium Nitrate, Water and Carbon dioxide gas.
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
Dilute hydrochloric acid (HCl) is used, and this fizzes due to the presence of calcium carbonate (CACO3) in limestone
