What information does the periodic table give you?
Answers
The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.
The periodic table is divided using groups (columns) and periods (rows).
Each specific group or period has a specific pattern in the elements.
The modern periodic table is arranged in order of increasing atomic number.
I’m not really sure what information what you were asking for but I hope this helps..
The modern periodic table was created by Dmitri Mendeleev with the main goal of showing rows and columns with a logic arrangement of chemical elements.
In each column, the groups, the elements have the same number of electrons in the outermost shells. While the rows are called periods or series.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

The forces from below the surface that change the surface of the earth are
Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers
Answers
Correct! The forces from below the surface that change the surface of the Earth include:
1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

Oil is a powerful source of energy used for cars, machines, and many other purposes. While studying sources of energy that could replace the use of oil, a student thinks about solar power, wind power, nuclear power, and electric batteries. The students asks,"Which type of source will waste the least energy and provide the most energy in all situations?"
Which best describes why a scientist would ask a different question than this one?
O The question asks about subjective personal preferences regarding energy.
O The question focuses on the objective measurements of amounts of energy.
O The question has too wide of a focus, as though all situations can be studied at once.

On the way to school, Ellie sat on a bench waiting for her friend. She noticed snow all around her. Later that day, Ellie and her friend walked home and passed the same bench. Ellie's friend said, “There is a puddle in front of the bench. It must have rained while we were in school, creating this puddle.”
Ellie disagreed. She had a different claim about how the puddle formed based on the evidence from her observations. Ellie's evidence was as follows:
The park was covered in snow that morning but not in the afternoon.
Ellie didn’t need her jacket on the way home because it was so warm.
It was sunny all day.
Do you think the puddle was formed from rain? Why or why not?
Answers
Answer:
No, the puddle was formed because of the sun, because if there was snow and it rained then it would have turned slippery or icy
Explanation: If Ellie didn’t need a jacket but there was still some snow that means that it snowed the night before and melted today because the temperature became higher not because it rained
In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.
