How do you think chemical change is defined?

Answers

A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.

Which of the following is true about the picture above? What would it be?

Answers

Answer:

Container A is a solution and Container B is a colloid.

Explanation:

Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.

Container B is a suspension or a colloid as you can see the beam through the glass.

The first option proposes Container A is a colloid...this is not correct

The third option is not true as the tyndall effect is only displayed in container B

The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution

Water molecules are polar because the
water molecule has a linear shape.
water molecule has a bent shape.
oxygen atom has fewer electrons around it.
hydrogen atom forms an ionic bond with oxygen.

Answers

Answer: B (water molecule has a bent shape)

Explanation:

Water molecules are polar molecules because of their shape. Water molecules have one side that is positively charged due to hydrogen atom which is partially positive and the other side which is negatively charged, due to the oxygen atom.

When two molecules get close to each other the polar forces of attraction brings them close to each other. Oxygen bonds with several hydrogen atoms in the other water molecules resulting to hydrogen bonds.

a. The sharing of all electrons
b. The transfer of all electrons
c.
The transfer of valence electrons
d. The sharing of valence electrons

Answers

Answer:

The sharing of valence electrons

Explanation:

A covalent bond is formed when two or more atoms share valence electrons.

In BeCl2, electrons are shared between the beryllium atom and two chlorine atoms.

Owing to the large difference in electronegativity between the two elements, the bond is polar covalent.

how many picoliters are in 3.16 mL

Answers

Answer:

3.16×10⁹ pL

Explanation:

Given data:

Volume in mL = 3.16

Volume in picoliters = ?

Solution:

Picoliter and milliliters are units of volume. Milliliter is greater unit than picoliter.

1 mL = 10⁹ pL

Now we will convert the 3.16 mL into pL.

3.16 mL × 10⁹ pL/ 1 mL

3.16×10⁹ pL

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

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.

When 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.

Which of the following is a CORRECT statement?


Chemical change cannot be undone or reversed.


Physical change often cannot be undone or reversed.


In chemical change, you end up with the same substance you started with.


In physical change, particles of 2 or more substances rearrange to form new or different substance.

Answers

ANSWER: Chemical change cannot be undone or reversed.

Answer:

Detail is given below.

Explanation:

1) Chemical change cannot be undone or reversed.

The given statement is correct. Because,

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible .

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood  and this reaction can not be reversed.

2) Physical change often cannot be undone or reversed.

The given statement is incorrect.

Physical Change                                                                                              

The changes that occur only due to change in shape or physical properties but their chemical or internal composition remain unchanged.  

These changes were reversible.

Example :

Water converting to Ice

Water converting to gas

3) In chemical change, you end up with the same substance you started with

The given statement is incorrect. Consider the following example.

The reaction of Hydrogen and oxygen:

H₂ (g)  + O₂  (g) -------------------------------------> 2H₂O  (l)

A totally new compound is formed when oxygen and hydrogen are undergo reaction which is water.

4) In physical change, particles of 2 or more substances rearrange to form new or different substance.

The given statement is incorrect.

When particles rearrange them selves the different substance is not formed. Consider the example of water when it converted into ice or vapors. Only phase is changed but water retain its properties so new substance is not formed.
