Containers of ice cream are sold by volume, not by weight. Some ice cream manufacturers pump air into the ice cream before packaging it. Why does this practice make the ice cream more expensive to the consumer?
A) Air weighs more than ice cream does.
B) Air weighs less than ice cream does.
C) After air is pumped into ice cream, the mixture occupies a greater volume than the ice cream alone did.
D) After air is pumped into ice cream, the mixture occupies a smaller volume than the ice cream alone did.
Pumping air into ice cream increases its volume, making consumers pay more for a lower actual amount of ice cream by volume. This is why ice cream with added air is more expensive. The correct answer is option C) After air is pumped into ice cream, the mixture occupies a greater volume than the ice cream alone did.
Ice cream manufacturers often pump air into the ice cream before packaging it. This practice makes ice cream more expensive to the consumer because the resulting mixture occupies a greater volume than the ice cream alone did. Therefore, consumers are paying more for a lower actual amount of ice cream by volume.
Let's explore why this is the case:
Volume vs. Weight: Ice cream is sold by volume, and pumping air into it increases its volume. This means a container still measures the same volume of product, but it contains less actual ice cream.Density: When air is added, the density of the ice cream mixture decreases. This means there is more air and less ice cream in the same volume.Consumer Impact: Since consumers buy ice cream by volume, they end up paying more for less actual ice cream.In 1895, X-rays were accidentally discovered during a scientific experiment.

470,809 mi express in an integer
Answer: The given number is already an integer.
Explanation:
Integer is defined as a whole number which is not a fraction. This number can be positive, negative or zero.
Decimal numbers are not considered as integers. They are rounded off to write an integer.
For Example: 4, -2 and 0, all are considered as integers.
We are given a number having value 470,809 miles. The number is already a whole positive number.
Thus, the given number is already an integer.

Calculate the atomic mass in grams of 0.35 moles of CH4
Answer: 5.6 grams
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
Thus mass =[tex]{\text {number of moles}}\times {\text {Molar mass}}[/tex]
For [tex]CH_4[/tex]
Moles of [tex]CH_4[/tex]= 0.35 moles
Molar mass of [tex]CH_4[/tex] = 16 g/mol
Putting values in above equation, we get:
mass =[tex]0.35moles\times 16g/mol=5.6 g[/tex]
The atomic mass of 0.35 moles of [tex]CH_4[/tex] is 5.6 grams.

A sample of a pure ionic compound has a mass of 2.00 g. If 0.72 g of the sample is determined to be made up of calcium, what is the formula of the compound?
A. CaO
B. CaF2
C. CaS
D. CaCl2
E. CaSe
F. CaBr2
What we can actually do is to find the number of moles of Ca.
moles Ca = 0.72 g / (40.08 g/mol) = 0.018 mol
From the given choices, we can all see that there are 1 mol of compound per 1 mole of Ca. Therefore the actual moles of compound is also 0.018 mol. From this, calculate the mass and the answer is the one which will give 2 g.
Answer:
D. CaCl2

what did the professer use a catalyst for the flubber experiment
Final answer:
A catalyst is used to speed up the flubber experiment. Borax is a possible catalyst that can accelerate the formation of flubber by lowering the activation energy and promoting the reaction between polyvinyl acetate glue and borax.
Explanation:
A catalyst is a substance that speeds up a chemical reaction without being consumed in the process. In the flubber experiment, the professor most likely used a catalyst to accelerate the formation of flubber. One possible catalyst that could be used in this experiment is sodium borate, also known as borax.
The reaction between polyvinyl acetate glue and borax in the presence of water leads to the formation of cross-linked polymer chains, creating the bouncy and stretchy substance known as flubber. The borax acts as a catalyst by lowering the activation energy of the reaction, allowing it to occur more quickly.
By using a catalyst, the professor was able to demonstrate the reaction between the glue and borax more efficiently, saving time and ensuring a successful flubber formation.

Which of the following most likely happens during a chemical change? No new substances are formed. Properties of a substance remain unchanged. Composition of a substance is same as before. Different atoms than before are introduced after the change
Answer: During a chemical change, different atoms are introduced after the change than before the change.
Explanation: Chemical reactions are defined as the reaction in which two or more substances react to form a new substance. The composition of the reactants change completely when the product is formed in a chemical reaction.
For example: Formation of rust when iron metal is exposed to air and moisture for a long time.
Equation follows:
[tex]2Fe(s)+\frac{3}{2}O_2(g)\rightarrow Fe_2O_3[/tex]
So, During a chemical change, different atoms are introduced after the change than before the change.
Which is NOT unique to each element?
A. proton number
B. atomic number
C. neutron number
D. chemical symbol
Final answer:
The neutron number is not unique to each element.
Explanation:
The correct option is C. neutron number.
While proton number (also known as atomic number) and atomic number are unique to each element, representing the number of protons in the nucleus of an atom, the neutron number can vary for different isotopes of the same element.
The chemical symbol is also unique to each element, representing an abbreviation used to identify the element or its atoms. Each element on the periodic table is assigned a unique chemical symbol.
The correct answer is C. Neutron number is NOT unique to each element.
Each element in the periodic table is defined by its atomic number, which is the number of protons in the nucleus of an atom of that element. The atomic number is unique to each element and determines its position in the periodic table. For example, hydrogen has an atomic number of 1, meaning it has one proton in its nucleus, and helium has an atomic number of 2, meaning it has two protons.
The proton number, which is another term for the atomic number, is also unique to each element. Therefore, options A and B (proton number and atomic number) are unique to each element.
On the other hand, the neutron number is not unique to each element. Different isotopes of the same element have different numbers of neutrons. For instance, the most common isotope of carbon is carbon-12, which has 6 neutrons, but there is also a carbon-13 isotope, which has 7 neutrons, and a carbon-14 isotope, which has 8 neutrons. All these isotopes are still carbon because they have the same atomic number (6 protons), but they have different neutron numbers.
The chemical symbol is a shorthand way to represent an element and is also unique to each element. For example, the chemical symbol for carbon is C, for oxygen is O, and for hydrogen is H. These symbols do not change regardless of the isotope or the number of neutrons present in the nucleus.

Compare the solubility of olive oil and acetic acid in water. Why is one substance more soluble than the other?
Acetic acid is highly soluble in water due to its polar nature, while olive oil's nonpolar properties result in low solubility.
Acetic acid is highly soluble in water due to its polar nature, allowing it to interact with water molecules through hydrogen bonding. On the other hand, olive oil is nonpolar and lacks the ability to form significant interactions with water, resulting in low solubility.
The presence of a carboxylic acid group in acetic acid facilitates its solubility in water by enabling hydrogen bonding with water molecules. In contrast, the predominantly nonpolar nature of olive oil limits its solubility in water due to a lack of interactions with water molecules.
Overall, the polar vs. nonpolar properties of acetic acid and olive oil play a crucial role in determining their solubility in water.
