What else can I help you with?
Why might you expect magnesium carbonate to behave in a similar way to calcium carbonate?
Both magnesium carbonate and calcium carbonate are alkaline earth metal carbonates with similar chemical properties. They have comparable solubility behaviors and both can act as antacids to help neutralize excess stomach acid. Additionally, they both form insoluble precipitates when reacting with carbonic acid.
If you heated limestone how would you expect the mass of the limestone to compare with the mass of calcium oxide?
When limestone is heated, it undergoes a chemical reaction that releases carbon dioxide gas, leaving behind calcium oxide. As a result, the mass of the limestone would be greater than the mass of the calcium oxide produced, due to the loss of carbon dioxide during the reaction.
If you add a small amount of hydrochloric acid to 4 liters of water what type of solution would you expect to have?
You get a dilute solution. With 4 litres of water, you have more solvent (H2O) than solvent (HCl) than you originally had.
What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
Would you expect the carbonate alkalinity to be higher or lower for temporary hard rather than permanently hard water?
The carbonate alkalinity would be higher in temporary hard water compared to permanently hard water. Temporary hard water primarily contains bicarbonate ions, which contribute to the carbonate alkalinity, while permanently hard water contains other ions, such as sulfate or chloride, which do not significantly contribute to carbonate alkalinity.
Should a homeowner expect more calcium carbonate build up in hot water pipes or cold water pipes?
Cold for the calcium carbonate is disolved by hot water.
Why might you expect magnesium carbonate to behave in a similar way to calcium carbonate?
Both magnesium carbonate and calcium carbonate are alkaline earth metal carbonates with similar chemical properties. They have comparable solubility behaviors and both can act as antacids to help neutralize excess stomach acid. Additionally, they both form insoluble precipitates when reacting with carbonic acid.
How would you distinguish between zinc nitrate and calcium nitrate?
One way to distinguish between zinc nitrate and calcium nitrate is through a flame test. When heated in a flame, zinc nitrate emits a green color, while calcium nitrate emits a red color. Additionally, chemical tests such as adding a carbonate compound can help differentiate them. Zinc nitrate forms a white precipitate with sodium carbonate, while calcium nitrate forms a white precipitate that dissolves in excess carbonate.

Which statement is an example of an observation the students could have made?
Well, we didn't expect that!
Would you expect to find calcium chloride in ocean water?
what do you expeat to find in calcium chloride in ocean water
What element would you expect to behave the most like calcium?
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
Do observation essays have a thesis statement?
Yes, observation essays typically have a thesis statement that conveys the main point or purpose of the observation being discussed. The thesis statement helps to guide the reader on what to expect and establishes the focus of the essay.
If you add a small amount of hydrochloric acid to 4 liters of water what type of solution would you expect to have?
You get a dilute solution. With 4 litres of water, you have more solvent (H2O) than solvent (HCl) than you originally had.
Would you expect to find Calcium uncombined in nature?
yes because it id a natural element and you would get it and make milk out of it
If one adds 5 grams of sodium chloride and 5 grams of calcium chloride to water at what temperature would you expect the solution of sodium chloride and calcium chloride to boil?
You get salt at the bottom of the pan!
