37.8 grams of CS2 equals to 37.8/76=0.5 mole. So the products have 0.5 mole CO2 which is 11.2 liters at STP. So according to the gas law, the volume at given condition is 12.4 liters. So the answer should be 12.2 liters.
Answer:
You need the Delta H fusion for water. Multiply that by 50 grams. Then multiply 50 g x 4.184 x 65 to get joules to raise water to 65 degrees. Add these values together to get total joules.
Explanation:
A. pH meter is the instrument which will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.
Litmus paper is just a paper which changes color based on whether the solution is an acid or a base. Phenolphthalein is an indicator which changes color based on pH values. And bromthymol blue doesn't tell concentrations, it is just a pH indicator for weak acids and bases.
An anion is a negatively charged ion.
Hope this helps xox :)
