What is the opposite force to pushing off the ground to jump?
Answer:
Newton's Third Law of Motion states that to every action there is an equal and opposite reaction. When the earth pushes on you to send you into the air after jumping, you also push on the earth with the same force. But forces are different from accelerations. A force F is a push or pull on an object
Explanation:
Answer:
Friction
Explanation:
Friction causes an opposite force
why do the Noble gases have the highest ionization energies across a period?
Answer:
ionization energy decreases from top to bottom in groups, and increases from left to right across a period. So technically, the noble games have the largest ionization energy.

We can verify the properties as follows;
1) Sour taste - Put some soda on your tongue
2) Corrode metals - Put a little soda on a clean metal surface
3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calculate the density of the solid.
Answer:
The answer is 8.40 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]
We have the final answer as
8.40 g/mLHope this helps you

please help this is worth half of my grade! what letter represents the trough of the wave a,b,c,d,e
Hello good afternoon...God bless the answer to your following question is D
because...A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

In ecosystem, particles are carried as bed load by rubbing particles together.Path of stream can be varied depending on amount of humus present in soil and is measured in cubic meters per second and carrying capacity depends on type of material through which stream flows.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

How many Oxygen molecules are present? ___________
How many N2O molecules are present? ___________
The molecules of Nitrogen, oxygen, and N₂O are 2, 1, and 2 respectively.
What is the chemical equation?A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.
The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.
According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.
Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:
2N₂ + O₂ → 2N₂O
The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.

When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.

The diagram above shows the distribution of speeds for a sample of N2(g)
at 25°C
. Which of the following graphs shows the distribution of speeds for a sample of O2(g)
at 25°C
(dashed line) ?
Answer:
A
Explanation:
The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.
Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.
Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.
For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

lonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.
