How many electrons, protons, and neutrons are contained in the 17o?

Amanda [17]3 years ago

The Atomic Number and Atomic Mass of ¹⁷O are 8 and 17 respectively.

Atomic Number:
                         Atomic Number of Element is the Number of Protons contained by the Element. So, there are 8 Protons in ¹⁷O.

Atomic Mass:
                     Atomic Mass of Element is the total number of Protons and Neutrons present in the Nucleus of that element.
So,
                    Atomic Mass  =  # of Protons + # of Neutrons

As the Atomic mass of ¹⁷O is 17 and it has 8 protons, So # of Neutrons are calculated as,

                     # of Neutrons  =  Atomic Mass - # of Protons

                     # of Neutrons  =  17 - 8

                     # of Neutrons  =  9
And,
As there is no charge on ¹⁷O, so the number of Electrons and Protons are equal. i.e.
                     # of Electrons  =  8

Result:
             
In ¹⁷O Number of Neutrons are 9, Number of Protons are 8 and Number of Electrons are 8.

A child pushes a desk with a force of 15 N to the right. The desk accelerates to the right. Which of the following statements co
ratelena [41]

Answer:

The answer to your question is: number 1

Explanation:

Third law of Newton: says that for every action ,there is an equal and opposite reaction.

So, if the child is pushing an object to the right, it will recipe the same amount of force that he is exerting to the object but in opposite direction.

Number 2 and 3 are incorrect because, because the third law of Newton says "an equal and opposite reaction", not slightly more or less.

Number 4 is wrong, it is not in agreement with Newton's third law of motion.

The reaction of glucose, c6h12o6, with oxygen produces carbon dioxide and water. what is the sum of the coefficients in the bala
Misha Larkins [42]

The balanced equation for the given reaction:

C₆H₁₂O₆ (glucose) + 6O₂→ 6CO₂ + 6H₂O

So in the balanced equation the coefficients before glucose, oxygen, water and carbon dioxide are 1, 6, 6 and 6 respectively.

Therefore, the sum of the coefficients in the balanced equation

= 1 + 6 + 6 + 6

= 19

The correct answer is 19.

Breaking an object such as a mirror is an example of physical change, chemical change,physical reaction, chemical reaction
dangina [55]

Answer:

option A= Physical change

Explanation:

physical change:

" It is a change in which no new substance is formed"

Breaking of object like glass is the example of physical change because it is not change into another object. It effect the form of object but can not change the chemical composition.

Chemical changes:

" it is a change in which one substance is converted into new product through chemical reaction".

During the chemical changes the types and the number of atom remain same but their arrangement changed.

for example: burning of wood, baking of cake, digesting food, resting of iron etc.

Physical reaction:

" physical reaction occur during the molecular rearrangement. There is no chemical change occur"

In this type of changes no bonds are break to form new bonds, for example boiling point.

Chemical reaction:

" chemical reaction occur when molecules are chemically react with each others and bonds formation and breaking is also occur"

A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial
V125BC [204]

The fact that the student used different amount of water (another independent variable) is wrong with the experimental design

WHAT ARE THE COMPONENTS OF AN EXPERIMENT?

  • An experiment aims at solving a scientific problem or answering a scientific question. An experiment should contain a variable being changed called INDEPENDENT VARIABLE and a variable being measured called DEPENDENT VARIABLE.

  • In an ideal experiment, only one independent variable should be used while every other variable should be kept constant. This is done so as not to affect the result of the experiment.

In the experiment conducted by the student in this question, two independent variables were used i.e. the different amount of water and the different temperatures. This is what is wrong about the experimental design.

  • In a nutshell, the fact that two independent variables were used by the student is what is wrong about the experimental design.
