A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42
Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42
Newtons. With what force does the scale push back up against her feet?
Answer:
The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

Which metal reacts spontaneously with NiCl2(aq)?
A) Au(s)
B) Cu(s)
C) Sn(s)
D) Zn(s)
Answer:
THE answer IS B)cu(s)
Explanation:
HOPE ITS HELP
The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

How do microorganisms influence the chemical characteristics of soil? Explain Please.
Answer:
Soil microbes are also important for the development of healthy soil structure. ... Soil microorganisms are both components and producers of soil organic carbon, a substance that locks carbon into the soil for long periods. Abundant soil organic carbon improves soil fertility and water-retaining capacity.

Complete the sentences to identify the difference between a nonmetal atom and its anion.
In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.
In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.
key bank:
- a positive
- no net
- electrons
- protons
- a negative
- neutrons
Answer:
more protons than neutrons and the number of electrons and blank are blank
Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
Please don't just give the sample response.
Answer:
The food coloring mixes much faster in the hot water than it mixes with the cold water. This is because in the hot water, water molecules have more energy and are moving faster than the molecules of cold water.

compound
element
Answer:
Mixture
Explanation:
When a prospector scoops up part of the stream bed, the pan contains stream sediments.
The term that best describes what is in his pan when he scoops up part of the stream bed is the mixture. Thus, the correct option for this question is A.
What is a Stream bed?A stream bed may be defined as the strait extremity of a stream or river through which the physical confine of the normal water flow. It is a type of channel significantly occupied by a stream.
According to the context of this question, when a prospector scoops up part of the stream bed, the pan contains stream sediments, which implies that the mixture contains stream sediments or contamination.
Therefore, the mixture is the term that best describes what is in his pan when he scoops up part of the stream bed. Thus, the correct option for this question is A.

Low
Check ansive
Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.
Explanation:
Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".
The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).
In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
