Find the distance that a car traveled that went 50 miles per hour in 3 hours.
The car travels 50 miles per hour. To find the distance it travelled in 3 hours, multiple 50 by 3.
50 x 3 = 150
Therefore, the car would travel 150 miles in 3 hours.

Which of the following statements is true?
A. Magnesium (Mg) is brittle.
B. Iodine (I) is magnetic.
C. Copper (Cu) conducts heat.
D. Iron (Fe) has a low density.
Answer:
I think it's C.copper conducts heat
The elements of the periodic table are arranged in the families and periods based on their properties. Copper (Cu) is a transition metal that can conduct electricity. Thus, option C is correct.
What are transition metals?Transition metals are the metallic elements that are arranged in groups 3 - 12 and periods 4-7. They are also called d-block elements due to the electron present in the d orbit of the atom making them capable of bond formation.
They all show the properties of metals that include shininess, luster, conductivity, etc. The series include copper, iron, cobalt, gold, zinc, chromium, nickel, manganese, molybdenum, etc.
Copper being a transition metal has the property of conducting electricity and is used in wirings as they have loosely bounded electrons in their shell that can carry the electrical charge in a circuit.
Therefore, option C. copper (Cu) can conduct electricity and heat is correct.

Identify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force. CHCI3,CH3COOH, CO2
Answer:
CH3COOH
Explanation:
CH3COOH has the highest boiling point because it participates in the strongest intermolecular interactions. The -OH group can participate in hydrogen bonding with other -OH groups. Hydrogen bonds are very strong because they are the result of large partial positive charge on the hydrogen and large partial negative charge on the oxygen. When surrounded by other -OH groups, the partial positive charge on the hydrogen can form temporary bonds with the partial negative charge of an oxygen on another molecule. The stronger the intermolecular interactions, the more difficult they are to overcome, thus increasing the boiling point.
The strongest IMF the other molecules participate in are dipole-dipole. These interactions are not as strong as hydrogen bonding.

An unidentified flying object has crashed in your yard! An alien emerges from the wreckage. The alien tells you that it has traveled here from the planet Geela which is 5.670x10^3 light years away. How many miles away is Geela? 1.06 x 10^-16 light years = 6.21 x 10^-4 miles
Answer : Geela away is [tex]33.22\times 10^{15}\text{ miles}[/tex]
Explanation :
As we are given that the alien tells you that it has traveled here from the planet Geela which is 5.670 × 10³ light years away.
And we know that:
[tex]1.06\times 10^{-16}\text{ light years}=6.21\times 10^{-4}\text{ miles}[/tex]
Now we have to determine the distance away is Geela.
As, [tex]1.06\times 10^{-16}\text{ light years}=6.21\times 10^{-4}\text{ miles}[/tex]
So, [tex]5.670\times 10^{3}\text{ light years}=\frac{5.670\times 10^{3}\text{ light years}}{1.06\times 10^{-16}\text{ light years}}\times 6.21\times 10^{-4}\text{ miles}[/tex]
= [tex]33.22\times 10^{15}\text{ miles}[/tex]
Therefore, the Geela away is [tex]33.22\times 10^{15}\text{ miles}[/tex]
what are the similarities and differences of the light waves on material
Answer:
1. Sound is longitudinal waves, light waves is transverse
2. Sound is a mechanical wave, light is an electromagnetic wave
3. Speed of sound is less than the speed of light waves. For example, in air, sound travels at approximately 333.1 m/s, while light travels at about 3*10^8 m/s
4. Sound waves can't be plane-polarized while light waves can be polarized.

The deciduous forest supports a diverse ecology. A warm growing season with abundant moisture encourages plants to grow, and the ground is covered with small plants, flowers, ferns, and grasses. In spring the trees and shrubs produce new leaves and colorful flowers. In summer the tall trees cast shade on the forest floor, providing ideal growing conditions for shade-tolerant plants. Seeds and berries provide for plant reproduction, and feed small rodents and birds. The leaves that fall in the autumn provide plenty of material for decomposers, soil bacteria, worms, grubs, and fungi. All these plants together are the primary producers. If berries were destroyed and taken out of the food web, which organisms would be directly affected? *

The snake, the owl, and the fox would be directly affected by the loss of berries.
The mouse and the frog would be directly affected by the loss of berries.
No organisms in the food web would be directly affected by the loss of berries.
The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.
Answer:
The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.
Explanation:
Refer to the attached picture below.
The arrows in the diagram represent which way the energy flows. There are only three ways the energy flows directly to an organism. Those are to the grasshopper, the frog, and the rabbit. (in the picture below, these are circled in red.)
Therefore, we can assume that the correct answer would be D. The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.

5. A flame test can be used to identify an unknown element. A student reacts two chemicals and decides to perform a flame test on the resulting product. If the product gives off a magenta hue when in flames, which element is likely to be present? Use your lab data to help determine the identity of this element.
Answer:
The element that is likely to be present is LITHIUM.
Explanation: ABOUT FLAME TEST
An analytical chemistry method used to help identify metal ions is the flame test. It can not be used to classify all metals, although it is a useful qualitative research test and a lot of fun to perform, since not all metal ions emit flame colors. Some metal ions also display colors similar to each other, making it difficult to tell them apart. However, for the detection of various metals and metalloids, the test is still useful.
One downside of the flame test is that the light color that is detected depends very much on the flame's chemical composition (the fuel that is being burned). This makes it difficult to match colors with a chart that has a high level of trust.
The bead test or blister test, in which a bead of salt is coated with the sample and then heated with a Bunsen burner flame, is an alternative to the flame test. Because more samples stick to the bead than to a simple wire loop, this test is slightly more accurate and Since most Bunsen burners, which appear to burn with a clean, blue flame, are linked to natural gas.
ABOUT LITHIUM ELELMENT -:It's metal, but it's soft enough to cut with a knife .It is so light that water can float on it. It is hard to put out lithium fires. Lithium, along with hydrogen and helium, was one of the three elements that the Big Bang produced in vast amounts.
Hence , we identifies the element in flame test by the color produces that is magenta or pink-red which gives the element Lithium . Therefore , the correct answer is lithium.
