You carefully weigh out 20.00 of powder and add it to 81.00 of solution You notice bubbles as a reaction takes place You then weigh the resulting solution and find that it has a mass of 92.80?

Matter is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants must be equal to the total mass of the products.
First, find the initial mass by adding together the masses of the reactants. The final mass (92.80 ) is less than the initial mass because gas escaped during the reaction. The mass of that escaped is equal to the difference between the initial and final masses.
20.00+81.00= 101.00
101.00-92.80=8.200
8.200 g is the CO2 mass that was produced in the reaction.

How does carbonation effect density?
The air bubbles lower the density of the solution
Which one of the following is a double- displacement reaction?
AB + CD --> AD + BC the two compounds switch the cation and anion, producing two new compounds
Solid sodium carbonate is put into a solution of acetic acid forming gas bubbles and a clear aqueous solution What is the balanced full molecular equation for this reaction?
This equation is: 2CH3COOH + Na2CO3 --> 2NaCH3COO + CO2 + H2O .
What is a chemical reaction with an acid base?
bubbles
What is the formula of the bubbles produce from the reaction of an acid with marble chip?
Calcium carbonate is the name of the bubbles that are produced from the reaction of an acid with marble chips. This is an alkaline compound, and doesn't look different than foam or bubbles.
What is used to detect calcium carbonate in minerals?
Acids. The resulting fizz of CO2 bubbles indicates a reaction with a carbonate mineral.
What causes the bubbling of the solution?
Reaction in which bubbles are formed in solvent
How does carbonation effect density?
The air bubbles lower the density of the solution
Is bubbling champagne a solution?
Champagne is a solution. When bubbles come off, they are carbon dioxide gas coming out of solution, so the bubbling champagne is a solution with bubbles of gas in it. The champagne is still a solution, but the bubbles are not part of it any more.
Which one of the following is a double- displacement reaction?
AB + CD --> AD + BC the two compounds switch the cation and anion, producing two new compounds
How does vinegar have an affect on baking soda?
A chemical reaction releases carbon dioxide gas (lots of bubbles), and a solution of sodium acetate and water remain.
Why does it fizz when you mix baking soda and vinegar?
Because in the reaction between those two, Carbon dioxide (CO2) is produced which comes out of the solution as bubbles
Solid sodium carbonate is put into a solution of acetic acid forming gas bubbles and a clear aqueous solution What is the balanced full molecular equation for this reaction?
This equation is: 2CH3COOH + Na2CO3 --> 2NaCH3COO + CO2 + H2O .
Are bubbles made by a chemical reaction?
yes
What is a chemical reaction with an acid base?
bubbles
What is the formula of the bubbles produce from the reaction of an acid with marble chip?
Calcium carbonate is the name of the bubbles that are produced from the reaction of an acid with marble chips. This is an alkaline compound, and doesn't look different than foam or bubbles.
What is the name of the reaction between cola and Mentos?
That is a physical reaction called effervescence. The carbon dioxide is super-saturated in the coke and the surface of a mentos provides nuclei upon which the bubbles can form. You can see a more controlled formation of bubbles on nuclei if you fill a glass with coke and carefully scratch the inside of the glass with the corner of a triangular file. Where the glass is scratched, bubbles will form. It will be easier to see if you use a colorless carbonated beverage or plain carbonated water.
