describe how changing the particles changed the atom​

Answers

Answer: During chemical changes particles do change with atoms or ions regrouping . Bonds (links) between atoms break and new ones form and energy is either given out or taken in.

Explanation:

Chemical reactions make particles to change and resulting to change atoms or ions via regrouping .

What is chemical reaction?

The chemical reaction is the reaction between two reactants that led to the formation of products.

The products are substances that forms after reaction. The reactants are the substances which are original materials.

Bonds between atoms break and make new ones. In this process, energy is either rejected or taken in.

The particle are the electrons which are shared between the atoms of same or different elements.

The electrons in the valence get donated or accepted by the atoms and form bond. When the electrons are donated, the bonds break and when electrons are accepted, bonds are formed. So, the new element or compound is formed.

Thus, the chemical reaction are responsible for change in atoms due to change in particles.

An ant is Dragging a Housefly and Elephant is pushing a big tree which is not moving. who is doing work? The ant or the elephant? Justify Your Answer!​

Answers

Answer:

the ant

Explanation:

because work is done when there will be involvement of displacement in the direction of the force.

Answer:

The ant is doing work but the elephant is not

Explanation:

Work done = Force × Displacement

In case of ant and housefly,

Ants are dragging the housefly , so they are displacing the housefly from one point to the other by applying certain force , so we can say that they are doing work

In case of elephant and tree,

When the elephant is pushing the tree( applying force) , the tree is not moving which means that there is no Displacement, so work done will be

Work done = Force × Displacement

= Force × 0

= 0

equation D=mass/volume

D=m/v

example sample : D=m/v= 250/100 = 2.5 g/cm³

1- D=m/v = 454/2274 = 0.2 g/cm³

2- 1 liter = 1000 cm³

D=m/v=1000/1000= 1 g/cm³

3 - d=m/v

0.6 g/cm³=m / 1.2 cm³

m=0.6*1.2 = 0.72 g

If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?

Answers

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

[tex]m=\dfrac{h'}{h}[/tex]

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

[tex]m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm[/tex]

So, the size off the object is same as that of the size of the image i.e. 10 cm.

The elements least likely to form bonds are found in which group?
O 15
O 16
017
O 18

Answers

The answer is group 18.

Explanation:
Group 18 is known as the Noble Gases. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.

The element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.

What is group 18 of the periodic table known?

The elements of group 18 in the modern periodic table are known as noble gases. These gases are colorless, odorless, tasteless, and nonflammable under standard conditions.

They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.

Due to this fact, they would not have any ability to form bonds with other elements in order to produce compounds or molecules. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.

Therefore, the element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.
