Draw a graph of how kinetic energy & temperature are related
(LOOK AT THE PICTURE ATTACHED)
Answer:
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

What will happen if you add salt to water that is "saturated"? *
The salt will react with the water quicker because you're adding more reactants.
The added salt will sink to the bottom.
The salt will dissolve more slowly than usual.
Dissolved salt will precipitate out and sink to the bottom.
Answer:
The added salt will sink to the bottom
Explanation:
A saturated solution is that solution that contains the maximum amount of solute it can dissolve and ,hence, will no longer dissolve any more solute. This question is describing a water solution that is "saturated", this means that water can no longer dissolve any more solute because it has reached the maximum solute limit it can contain.
Hence, adding more solute to a saturated solution like the WATER being described in this question will result in the solute forming a PRECIPITATE at the bottom of the solution. Hence, in this water solution, adding salt to the saturated water solution will result in the added salt sinking to the bottom.

According to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.
According to the given chemical equation, 70.906 g of chlorine gives 117 g sodium chloride, thus, 2.4 g of sodium chloride will be produced, when 2.4×70.906/117= 1.45 g of Cl₂ reacts.
Thus, according to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.

Why was Wegener’s theory of continental drift almost completely discarded?
A. It didn’t explain how continents fit together.
B. It didn’t explain how mountains formed.
C. It wasn’t supported by fossil evidence.
D. It didn’t have a mechanism for how drift occurred.
Which of the following is evidence that the continents were once part of a supercontinent called Pangaea?
A. Island Arcs
B. Deep ocean trenches
C. Glacier scrapings
D. Mid-ocean ridges
Answer:
1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
Answer:
1. D
2. C
Explanation:
1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.
2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

A student increases the temperature of a 300 cm3 balloon from 40 °C to 110 °C.
What will the new volume of the balloon be? Round your answer to one decimal point.
(To convert, add 273.15)
Will Mark brainliest!!!
Answer:
367.1 cm³
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 40 °C
Final temperature (T₂) = 110 °C
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273.15
Initial temperature (T₁) = 40 °C
Initial temperature (T₁) = 40 °C + 273.15
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 110 °C
Final temperature (T₂) = 110 °C + 273.15
Final temperature (T₂) = 383.15 K
Finally, we shall determine the final volume (i.e the new volume) of the balloon. This can be obtained by using the Charles' law equation as illustrated below:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 383.15 K
Final volume (V₂) =?
V₁/T₁ = V₂/T₂
300 / 313.15 = V₂ / 383.15
Cross multiply
313.15 × V₂ = 300 × 383.15
313.15 × V₂ = 114945
Divide both side by 313.15
V₂ = 114945 / 313.15
V₂ = 367.1 cm³
Therefore, the new volume of the balloon is 367.1 cm³
Which energy resource produces the least amount of air pollution?
coal
natural gas
oil
hydropower
Answer:
hydropowered
Explanation:
took the test
Hydropower is the energy source that produces the least amount of air pollution. Therefore, the correct option is option D.
What is energy?Energy is The capacity or ability to do tasks, such as the ability to forcefully move an object. Energy can exist in a multitude of forms and can change from one to another, including thermal, mechanical, chemical, and nuclear energy. The flow of electric charges known as electrons is what generates electrical energy.
Energy is utilised to make a wide range of goods, power transportation, and power the appliances we use to heat and light our houses. The production of electricity is the main purpose of these various energy sources. All of these many energy sources contribute to the electrical power reserve that is then distributed to various locations via high-powered lines. Hydropower is the energy source that produces the least amount of air pollution.

What two types of matter are closest in
density? How do you know?
ings.
Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them
