when do meanders form in a river?

A.young
B.old
C.mature
D.rejuvenated

Answers

Answer 1

Answer:

The formation of a meander. As the river erodes laterally, to the right side then the left side, it forms large bends, and then horseshoe-like loops called meanders . The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.

You are about to take a short trip. However, you will not be traveling by car or bus; instead you will be traveling up in a hot air balloon. You know that hot air balloons, like the ones pictured, are able to rise when the air contained in them is heated. Why does the balloon rise? What is happening at the molecular level to make the balloon rise?

Answers

Answer:

Hot air rises. Heated air molecules “spread out” or expand and bounce around, and the space becomes less dense than the surrounding space. Increasing the air temperature inside the balloon envelope makes it less dense than the air, thus making it “lighter than air”.

Explanation:

I'm new to brainly but I hope this helped!

Balloon rise because  Warm air ascends. Heat causes the molecules of the air to "spread out," or expand, and bounce off one another, making the area less dense than the surroundings.

What are molecules ?

A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds.

Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.

Explanation:

Describe how calcium and fluorine bond together to form calcium fluoride. The electron arrangement of each atom is shown.

Answers

Answer:

Detail is given below.

Explanation:

Calcium is alkaline earth metal. It has two valance electron. Thus calcium needs six more electron to complete the octet. Thus, its very easy for calcium to remove its two electron and get complete octet.

Electronic configuration of Ca:

Ca₂₀ = [Ar] 4s²

While,

Fluorine is halogen. It has seven valance electrons. It needed only one electron to complete the octet. When it combine with calcium , calcium loses two electrons thus two atom of fluorine combine with one atom of fluorine and stable compound calcium fluoride is formed.

Electronic configuration of F:

F₉  = [He] 2s² 2p⁵

Chemical equation:

Ca  + F₂     →     CaF₂

A student drops a 95g object into a graduated cylindor that has 30ml of water in it. After the object is added to the cylinder the water level reads 63ml. What is the density of the object? ​

Answers

Answer:

The answer is 2.88 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 95g

volume = final volume of water - initial volume of water

volume = 63 - 30 = 33 mL

We have

[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]

We have the final answer as

2.88 g/mL

Describe what will happen to the pressure of the gas as the plunger is pushed in.

Answers

Answer:

The pressure of gas will increase.

Explanation:

The question above is related to "Boyle's Law." According to this law, provided that the temperature and amount of gas are stable, the absolute pressure of gas is inversely proportional to its volume.

In this sense, if the plunger will be pushed in, the volume of the gas will definitely decrease due to lack of space while the pressure will increase because the molecules of the gas are colliding with each other. The greater the collision, the greater the pressure. This explains the answer above.

What are alkali metals

Answers

Answer:

Alkali metals are highly reactive elements that appear to be silver and they are found in group 1 of the periodic table.  It consists of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).  As you go further down the group, the more reactive they are.  Those elements all react to water and air, so they must be kept in oil to preserve their state.  

Alkali metals are any of the elements lithium, sodium, potassium, rubidium, cuisine, and francium, occupying Group 1A (1) of the periodic table. They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.

A large marble is dropped in a graduated cylinder with 45 mL of water in it. The water level increased to 61 mL. What is the volume of the marble?​

Answers

Answer:

Volume of the marble is 16 ml.

Initial volume present in graduated cylinder=45 ml.

Final volume in graduated cylinder after marble is dropped=61 ml.

Volume of water displaced=volume displaced by marble.

Volume displaced by marble=final volume in cylinder-initial volume in cylinder

Volume displaced=61ml-45ml=16ml

So volume of marble=16ml.

Answer:

16mL

How much space does 2 x 10^22 atoms of copper take up?

Answers

Answer:

2.35mL

Explanation:

The amount of space a substance holds is its volume.

Density = mass (g) /volume (L)

Where;

mole = mass/molar mass

Since 1 mol of Cu contains 6.022 × 10^22 atoms.

There are 2 x 10^22/6.022 × 10^22 moles in 2 x 10^22 atoms of copper

2 x 10^22/6.022 × 10^22

2/6.022 × 10^(22-22)

0.332 × 10^0

0.332mol

Mole = mass/molar mass

0.332 = mass/63.5

mass = 63.5 × 0.332

mass = 21.08g

Density = mass/volume

Density of copper (Cu) is 8.96 g/cm³

8.96 = 21.08/v

V = 21.08/8.96

V = 2.35mL or cm³

Answers

Answer:

There is an overall release of energy when bonds form.

Explanation:

There is a general release of energy when bonds form. This energy is called bond energy.

Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
