Imagine you are working in a laboratory that makes tablets for relieving indigestion. The tablets work by reacting with water or acid in the stomach. Carbon dioxide gas is produced as a result. You are asked to determine if taking the tablets with alcohol will affect the speed at which the tablets work.Describe how you will carry out your investigation. You can use any or all of the apparatus below. (You may include diagrams of your experimental set-up.)
• 3 (100 cm³) conical flasks
• 3 balloons
• 3 rubber bands
• 3 indigestion tablets
• water
• alcohol
• measuring cylinder
• stopwatch
• mass balance

Answers

Answer 1
Answer: well first I would grab a cylinder and pour water about half way and Than i would use the balloon to represent the stomach , i will fill the balloon up with alcohol mixed with water to represent the stomach's acid . Use the mass balance to check the weight of the stomach and how much (food) the person has ate , i could also do this by use the cylinder to check volume without removing any of its props. with one rubber band i would open the  the balloon and fold it back on the edge of the cylinder while the alcohol is in it, so you will see water at the bottom than the balloon filled with alcohol over it, when i'm done i will grab the stop watch to time whats about to happen . pickup the 3(100cm*3) conical flasks for a base .

than drop the 3 investigation tablets into the "stomach" balloon start the watch and see what happens.

i hope that this helps.    : )

Which statement best describes why specific heat capacity is often more useful than heat capacity for scientists when comparing two materials?Specific heat capacity is an intensive property and does not depend on sample size.
Specific heat capacity is an extensive property and does not depend on sample size.
Specific heat capacity is an intensive property and depends on the sample size.
Specific heat capacity is an extensive property and depends on the sample size.

Answers

The correct option is this: SPECIFIC HEAT CAPACITY IS AN INTENSIVE PROPERTY AND DOES NOT DEPEND ON SAMPLE SIZE.

Generally, all the properties of matters can be divided into two classes, these are intensive and extensive properties. Intensive properties are those properties that are not determined by the quantity of the material that is present or available. Examples of intensive properties are colour, density and specific heat capacity. For instance, whether you have a bucket of water or a cup of water, the quantity does not matter, the colour of water will always remain the same. Extensive properties in contrast, are those properties that depend on the quantity of material that is available. Examples are mass, heat capacity and volume.

Specific heat capacity is defined as the amount of heat required to increase the temperature of 1 gram of a substance by 1-degree Celsius.

The specific heat capacity is more often used for comparing materials, as it is an intensive property. Thus, statement A is correct.

What is the use of Specific Heat Capacity?

Specific heat capacity, which is also referred to as massic heat capacity, is the amount of heat added to 1 gram of mass to raise the temperature by 1-degree Celsius.

Specific heat is an intensive property and is not dependent on the size of the sample. This property of the specific heat is used to compare two materials.

Intensive properties are those properties that are not affected by the quantity of the material. Thus, statement A is correct, Specific heat capacity is an intensive property and does not depend on sample size.

If 20.0 mL of Ca(OH)2 with an unknown concentration is neutralized by 37.5 mL of 0.124 M HCl, what is the concentration of the Ca(OH)2 solution? Show all of the work needed to solve this problem. Ca(OH)2 + 2 HCl yields 2 H2 O + CaCl2

Answers

You first need to write the balanced chemical reaction for what is going on.
Ca(OH)₂+2HCl→2H₂O+CaCl₂

After you make the balanced chemical reaction, First you find the moles of HCl used.  To do this multiply 0.0375L by 0.124M to get 0.00465mol HCl.  Then you multiply 0.00465mol HCl by (1mol Ca(OH)₂)/(2mol HCl) to get 0.002325mol Ca(OH)₂.  Finally to find concentration of Ca(OH)₂ used you divide 0.002325mol by 0.020L to get 0.116M Ca(OH)₂.
Therefore the concentration of the unknown solution of Ca(OH)₂ was 0.116M.

Reaction rate is the speed with which reactants are converted to products in a chemical reaction. True or False?

Answers

True. Except that it is per unit of time. Units are important in order for our chemical reactions speed to be determined properly. 

Final answer:

The statement is true; reaction rate in chemistry refers to the speed at which reactants are transformed into products. Its rate is influenced by factors like concentration, temperature, and the presence of catalysts.

Explanation:

"Reaction rate is the speed with which reactants are converted to products in a chemical reaction," as stated above, is correct. In chemistry, the term Reaction Rate is used to describe how rapidly or slowly changes occur in a chemical reaction. It essentially provides information about how quickly reactants are transformed into products. Factors such as concentration, temperature, and presence of catalysts can influence the rate of a reaction.
