What are the two part of a hypothesis?
The two parts of a hypothesis is the observation and the test. An observation has to be made on what the experiment is going to be on, then a test has to be thought up to test the question.
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
Why Na2Co3 extract is not used for carbonate test?
because Carbonate ion present in NA2CO3 may make rkn backwards if carbonate ion is again added
How do you test purity of calcium carbonate?
This is possible by chemical analysis.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
What is the blood red residue formed in a glass test tube when copper carbonate is heated vigourously with carbon?
Elemental copper.
What happens to the falme when th burning splint is put into the mouth of the test tube with the test tube of solid calcium carbonate in it and then heated?
The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================
How do you test for carbonate ions?
1) Add a little hydrochloric to acid to a sample of the solid or solution you wish to test for carbonate ions 2) If effervescence is seen & the gas produced turns limewater milky white, the gas produced was carbon dioxide - this indicates that carbonate ions were present
What does the acid test tell you about a mineral?
The acid test tells you whether it is a carbonate or not.

What is the use of objective and systematic observation to test observation to test theory that is employed by sociologist?
The Scientific Method
What test could you do to see if there is Sodium Carbonate Gas?
Sodium Carbonate is not a gas it is a solution. I think you mean how can you test for Carbon Dioxide - bubble it though limewater and you will get Sodium Carbonate.
What does Lithium carbonate look like in a flame test?
need to find the answer to what doe slithium carbonate look like in a flame test
How can you test a rock to see if it contains calcium carbonate?
The traditional test is to put a few drops of 5% hydrochloric acid on it; carbonate minerals produce bubbles of carbon dioxide. This doesn't specifically test for calcium carbonate. It could be magnesium carbonate or some other carbonate mineral instead. Making sure it's calcium requires more elaborate equipment such as a flame emission spectrometer.
What happens when you heat sodium bicarbonate?
You get solid sodium carbonate, carbon dioxide gas, and water vapor or... Na2CO3(s) + CO2(g) + H2O(g)
The acid test tells whether a mineral is .?
a carbonate
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
