which is a mixture?
A. Water reacting with oxygen
B. Salt dissolved in water
C. Sodium and chlorine in a molecule
D. A solid aluminum pan
Answer:
B. salt dissolved in water
Explanation:
a mixture is multiple substances mixed together
Working with one sample at a time, add water to the glass one tablespoon at a time. Water should soak the sample from the bottom up. Count the number of tablespoons of water it takes to bring the water level up to the top of the sample. Record the amount in the chart.
Calculate the porosity of each sample using this formula, and record the results in the table. “Total sample volume” is the amount of soil, sand, or pebbles in the sample. A half cup is equal to 8 tablespoons.
% porosity = (amount of water added to sample ÷ total sample volume) × 100
PEBBLES -
SAND -
SOIL -
Answer:
1. Fill a drinking glass with a cup of water (1 cup =237 ml). Add sugar one teaspoon at a time until you have added 5 teaspoons. Stir and wait until each teaspoon dissolves completely. Between each teaspoon, take a sip and see how “the drink” tastes. After 5 teaspoons you will have added ~ 25 grams, i.e. slightly less than there is in one cup of coca-cola. After how many teaspoons is the drink pleasantly sweet? After how many teaspoons is it way too sweet?
2. Pour half of the sugar-water into a separate drinking class and put it aside for later.
3. To the remaining sugar water solution (~1/2 cup), add small amounts of vinegar, approximately 1/4 teaspoon at a time, taking a small taste after each addition. Keep track of how much vinegar you are adding. How much did you have to add for the drink to taste good to you? Put this glass aside for later comparison.
4. Now fill another drinking glass with half a cup of water (1/2 cup =120 ml), and add the same amount of vinegar that you added to the sugar-water in step 3 in order for it to taste delicious. In other words, you will now have three cups: one with sugar-water, one with sugar-vinegar-water, and one with vinegar-water. Have a taste of the vinegar-water. How does the vinegar-water taste compared to the sugar-vinegar-water drink? To the sugar-water drink?
This is the secret of Coca-Cola! Coca-cola contains a lot of sugar, probably way too much for most people to find tasty. But by adding acid (and some other flavors as well) you can get a tasty drink!
This is an example of the complex ways in which taste molecules can influence each other, and recipes often exploit this fact. By having different flavors play off each other, the crafty cook can adjust the overall flavor experience of a food. This is a similar reason to why some cooks add a bit of sugar to balance out the acidity of tomatoes in a tomato sauce. And Nathan Myhrvold, whom we will hear from later in this course, even goes so far as to add salt to red wine to make it taste better!
Questions:
1. Calculate how many moles of sugar per liter you added to your drink in step 1 before starting to add any vinegar. The molecular weight of sugar (i.e., sucrose) is 342 g/mol, and 1 teaspoon corresponds to approximately 5 grams. Enter your answer to two decimal places, and do not include units.

2. Calculate the concentration of hydrogen ions in moles per liter in your drink after you added 1.5 tsp of vinegar. You can use the table above which approximates the pH when adding certain amounts of vinegar to water. Enter your answer to one non-zero digit, and do not include units.

EXPERIMENT: DETERMINING VOLUME
Here are your goals for this lesson:
Measure a common geometric shape in centimeters and record answers
Calculate volume for the geometric shape
Utilize the method of displacement to determine volume
Answer questions and summarize results
If you ever dropped something into a full pail of water, you might have noticed that some of the water flowed over the edge of the pail. Whatever was dropped into the pail took up some of the space that had been filled by the water. As a result, some of the water was displaced from (pushed out of) the pail. The amount of space that matter takes up is called the volume of that matter. Thus a giant boulder has more volume than a small rock. Any unit of matter, large or small, solid, liquid, or gas, takes up space and therefore has volume.
In this experiment, you will attempt to determine the volume of two objects, using two different methods, listed below:
1. For an object of uniform shape having linear sides or a common geometric shape, measure the object and determine the volume mathematically.
2. For an irregularly shaped object that cannot be measured easily or does not consist of uniform geometric shapes, determine the volume of water it displaces. The volume of water displaced equals the volume of the object as long as the object does not absorb or dissolve in water.
When measuring the volume of water in a graduated cylinder or similar container, be sure you read the lowest point of the curved surface of the water, the meniscus. Study Figure 1 to find the correct level.
1. Find the volume of an object with linear sides or a common geometric shape.
These supplies are needed: a metric ruler and an object with linear sides or a common geometric shape
A. Volume equals length times width times height (V = l × w × h). The amount of space that an object takes up is its volume.
B. Measure in centimeters (cm) the length, width, and height of the object and record your answers.
Note: Be sure you included the units (cm) with each measurement.
C. Multiply the length by the width by the height. This is the volume of the object.
Volume = l × w × h = _____ × _____ × _____ = _____ cm3
Since you went from linear measurement (cm) to cubic measurement (cm3 ), the units change and your answer will be in cubic centimeters (cm3 ).
2. Find the volume of an irregularly-shaped object.
These supplies are needed: string, water, small rock, graduated cylinder
A. Pour water into a graduated cylinder until it is about half full, stopping at one of the level marks on the cylinder.
B. Read and record the level of the water. This reading is the volume of the water. Be sure you are reading at the lowest point of the curved surface or meniscus. Study Figure 1 above to see how to read the correct level.
C. Tie the string on the rock and lower the rock completely into the water. Let it settle at the bottom.
D. Record the level of the water with the rock in it. This reading is the volume of the water and the rock.
E. Find the volume of the rock by subtracting the reading of the water from the reading of the water and the rock.
(water and rock) - (water) = _____ cm3. Your answer is the volume of the rock.
3. Compose a scientific summary of your method, observations, data, and conclusions. In addition, be sure to answer the questions below in your report.
Why does the first method for determining volume work only for a regular-shaped object?
Will the second method for determining volume work for any object or just an odd-shaped one? Why?
Is one method of measurement more accurate than the other? Why or why not?
Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
What did you find out from this investigation? Be thoughtful in your answer.
Anyone who answers improperly will be reported please only answer if you have the answer. Thank You :))
10 points and Brainliest for best answer! goood luck!
Explanation:
(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?
(Ans- A) Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.
(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?
(Ans-B) It will work for both regular and irregular shaped objects since both displace equal volumes of water.
(Ques - C) Is one method of measurement more accurate than the other? Why or why not?
(Ans-C) Both are pretty accurate, with some experimental errors which may creep in accidentally.
(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
(Ans - D) No, the method would not work because sugar being soluble, will dissolve in water.
No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.
(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.
(Ans- E) I learnt about determining volume of different objects from this investigation. (Sorry, I know its not a very thoughtful answer)
