use the facts that water has a higher specific heat than rock (such as Granite) to explain the differences in the temperature curves for the two cities in the graph.
Since water has a high specific heat, that results in water being able to store/require more energy in order to change it’s temperature. Since San Francisco is so close to water, that would mean that it’s temperature should vary less since water would be able to keep the temperature around the same value even if there was an increase or decrease in thermal energy.
what does it mean if elements are in the same group on the periodic table?
Answer:
mostly metals

Joe bought a roll of gray duct tape containing 5400 inches. If there are 5280 feet in a mile, how
many miles long is Joe's roll of duct tape?
Answer:
STANDARD: 0.085 mi, 450 ft, or 150 yds
METRIC: 0.137 km, 137.16 m, or 13716 cm
Explanation:
When a liquid freezes it’s particles get what?
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.
Its particles no longer have enough energy to overcome the force of attraction between them.hope this help!
What information does not need to be included a chemical waste label? Select one: Relative amounts of chemical compounds in the container. The date the waste container was filled completely. A description of the experiment the chemicals were used for. Names of the chemical compounds present in the container.
Answer:
A description of the experiment the chemicals were used for.
Explanation:
A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:
Chemical compound's name present in the container.Composition and physical state of the waste.Hazardous properties of the waste.The date of manufacturing.Amount of chemical compounds filled in the container.A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.
Hence, the correct answer is "A description of the experiment the chemicals were used for."
The correct answer is A description of the experiment the chemicals were used for.
A chemical waste label must contain all the information about any hazardous waste present in the container. It should clearly indicate the composition of the waste, the date of manufacturing and the amount of chemical compounds filled in the container. A chemical waste label does not need to mention the experiment for which the chemicals were used.

Pseudoscience has been the belief that are proportions that look scientific but are not. The use of the celebrated athlete for sponsorship is an example of pseudoscience. Thus, option B is correct.
What is pseudoscience?Pseudoscience has been defined as the claim and beliefs that are not testable and looks scientific but actually are not. They are the findings and propositions that can be considered scientific erroneously.
It includes subjective ideas and explanations based on various ideas and beliefs that are not proven scientifically. The use of an athlete for promotional and supporting a claim is an example of pseudoscience as the claim made is not proved scientifically but rather based on some famous person's statement.
Therefore, option B. the famous athlete for support is an example of pseudoscience.

A lead fishing weight of 39.7g is submerged in a graduated cylinder of water containing 75.0mL of water. The water level will increase to what volume in the cylinder?
Answer:
78.5 mL
Explanation:
Step 1: Given data
Mass of the lead fishing weight: 39.7 g
Volume of water in the graduated cylinder: 75.0 mL
Step 2: Calculate the volume of the lead fishing weight
The density of lead is 11.34 g/mL.
39.7 g × (1 mL/11.34 g) = 3.50 mL
Step 3: Calculate to what volume will increase the water level
The final volume of water will be equal to its initial value plus the volume displaced by the lead fishing weight.
V = 75.0 mL + 3.50 mL = 78.5 mL

Describe how gasoline, as a fuel, can undergo a chemical change.
Answer with Explanation:
A "chemical change" occurs when the structure of the molecules change. If there's no change in structure, it is called a "physical change." This also means that a chemical reaction has to occur for something to be considered a chemical change.
Gasoline when used as a fuel is being transformed into other forms of energy. It undergoes a process called "combustion."
When used as a fuel for cars, the gasoline is being burned to produce heat energy. This energy is then converted into mechanical energy that allows the car to move. Clearly, the gasoline has undergone a chemical change.

Explanation:
An atom is the smallest particle of matter that takes part in a chemical reaction.
It is made up of three fundamental subatomic particles.
Protons are the positively charged particles in an atom. Neutrons do not carry any charges and are neutralElectrons are negatively chargedBoth the protons and neutrons occupy a tiny center where the mass of the atom is concentrated. The region is called the nucleus.
Diffusion of Ammonia in an Aqueous Solution. An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface. The concentration of ammonia in the organic phase is held constant and is such that the equilibrium concentration of ammonia in the water at this surface is 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). Water and the organic are insoluble in each other. The diffusion coefficient ofNH3 in water is 1.24 x 10- 9 m 2/sCalculate the flux N_B. Explain.
Answer:
The Flux N_B = 0
Explanation:
So, we are given the following set of data or parameters which is going to help in solving this particular Question. So, let us take each at a time;
=> "An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface."
=>" 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). ''
With the information above, we can determine the N_A(which the question did not specify that we should calculate).
For the value of N_B, it will be equals to zero(0) because the insolubility of water in organic solvent.
what is the covalent bond for Hydrogen + Chlorine (HCI)
Answer:
HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.
Explanation:
Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.

Observe the nature changing around your home. You can observe plants, animals, and parts of your actual home as you begin to notice changes in matter. Collect data for two examples of changes in matter. Use the Changes in Matter observation questions to determine if your examples are physical or chemical changes.
Your answer should include two examples, the types of changes observed, and evidence of how the examples were formed. You can use this format:
Example 1:
Type of Change:
Evidence:
Answer:
Example 1. One change I observed was when cooking, I needed to boil water. The water was later evaporated due to the increase of heat from the stove below the pot. Heat traveled and transferred from the stove to the pot then the water. This change is from liquid to gas.
Example 2. I was mixing sugar into my tea, the sugar dissolved into the tea. This is an example of dissolving a solid into a liquid. The tea took the properties of the sugar and turned the drink sweet.
Extra, taking a hot shower and steam leaves the shower. This change is of evaporation.

The image represents a(n)
A) ion of xenon.
B) atom of xenon.
C) molecule of xenon.
D) compound containing xenon.
Answer:
B) atom of Xenon
Explanation:
Xenon is already stable alone, because it has a complete octet, or 8 electrons. This graph is not an ion because it shows xenon is its default state, consisting of 8 electrons.
It is not a molecule because a molecule is a group of atoms, or a compound, what is shown is a singular atom.
