Yes
No
Not enough information
A researcher began the following reaction with 52.6 grams of sugar and Sulfiric Acid in part A. The final mass of the products in part B would MOST LIKELY be:
More than 52.6 grams
Less than 52.6 grams
Exactly 52.6 grams
Cannot be determined
Group 1 uses a balloon to contain gas from a baking soda and vinegar reaction, while Group 2 does not. How would the final mass in Group 2's experiment compare to Group 1's, and why?
The final mass in Group 2's experiment will be greater than Group 1's, because gas is allowed to enter the flask from the room, increasing the final mass.
The final mass in Group 2's experiment will be less than Group 1's, because gas is allowed to escape the flask, decreasing the final mass.
The final mass in Group 2's experiment will be the same as Group 1's, because mass is always conserved during chemical reactions.
The final mass in Group 2's experiment will be greater than Group 1's, because mass is always added during chemical reactions.
