How do core electrons relate to the ionization energy of the atom?

Answers

Answer:

For any given element, ionization energy increases as subsequent electrons are removed. For example, the energy required to remove an electron from neutral chlorine is 1251 kJ/mol. ... An even sharper increase in ionization energy is witnessed when inner-shell, or core, electrons are removed.

Present Your Findings
1. Make a graph of the data collected.
a. Label the x-axis as time.
b. Label the y-axis as the number of undecayed atoms.
c. Be sure to title the graph.
d. Turn the graph into your teacher.
2. Write a summary paragraph discussing this experiment and the results. Use the following questions to help guide the
content of your paragraph.
a. What was your hypothesis? According to your data, do you think your hypothesis was correct?
b. What is a half-life?
c. When does a radioactive sample emit the largest number of decay particles? Why is this information important?
(How can it be applied in our world today?)
d. Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds?
What does this reveal about radioactive decay?
e. Do you think the shape of the curve on your graph would change if you started with a smaller sample, say 50
atoms (pennies)? What does this reveal about radioactive decay?

Answers

Answer: To your project!!

Experiment Half-Life

a. My hypothesis is that when we get through 6 half-life’s you will be left with no atoms, and each time the atom number will decrease. Half of my hypothesis was correct whilst the numbers did decrease we, after 6 trials were left with one undecayed atom.

b.what is a half life?

the time required for the decay of one-half of the atoms in a sample of radioactive material

c. When does a radioactive sample emit the largest number of decay particles? when it first starts to decay

Why is this information important? Half-Life and decay is important today because it helps us determine the date of death and birth of ancient mummies.

d. Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds? Yes different data would arise and that would change the graph.

What does this reveal about radioactive decay? The longer a material or substance takes to decay the larger the amount of decayed material or substance will come from the substance

e. Do you think the shape of the curve on your graph would change if you started with a smaller sample, say 50 atoms (pennies)? Yes, again different data would arise and that would change the graph.

What does this reveal about radioactive decay? The smaller the sample the quicker it will decay. And the less product that comes from the sample.

Your project is done, it worked for me hope it does for you? DON'T USE THE EXACT SAME WORDS IT'S SUS

here is the graph too!

Answer:

Hey I dont know if you got the same project as me but I had to record pennies and make a graph so I recorded pennys here

Explanation:

first half-life =  tails 49 : heads 51

second half-life = tails 19 : heads 29

third half-life = tails 8 ; heads 11

fourth half-life = tails 2 ; heads 6

fifth half-life = tails 1 ; heads 1

sixth half-life = I didnt know what to say so I put 1

Find the mass of AlCl3 that is produced when 3.58 moles of Al2O3 react with excess HCl according to the following equation.

Answers

Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(l)

Moles of Al2O3, m = 3.58 moles.

We need to find the mass of AlCl3 produced.

Solution :

1 mole of Al2O3 produce 2 moles of AlCl3.

So, 3.58 moles of AlCl3 produce 7.16 moles of AlCl3.

Mass of AlCl3 produced is :

m = moles × molecular mass of AlCl3

m = 7.16 × 133.34 g

m = 954.714 g

Therefore, mass of AlCl3 produced is 954.714 g.

Hence, this is the required solution.

How do you find the mass in grams of one formula unit of a compound given all the atomic masses of every element in the compound?

Answers

Answer:

Explanation:

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).  The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.  (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)

Answer:

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

Explanation:

When a lithium atom becomes ionized its new electron configuration is 4 points
the same as which element?

A. Ar
B. Mg
C. He
D. Fe

Answers

Answer:

C. He

Explanation:

When lithium is ionized, its new electronic configuration is the same as that of a helium atom.

 Lithium is made up of 3 electrons with a configuration of:

                     2, 1

it has 1 electron in its outermost shell.

As a metal lithium will prefer to lose an electron due to its electropositivity.

    On losing an electron, it will have 2 electrons remaining

Now, Helium has 2 electrons and this makes it similar to Lithium that has lost one electron.

This makes Lithium isoelectronic with Helium.

Plants use a process called photosynthesis to survive. What
evidence proves this process is a chemical change?
A. They turn green and change space
B. They get taller and change size
C. Water is needed
Glucose is created in the chloroplasts

Answers

Answer:

D

Explanation:

Glucose is produced through a process powered by sunlight that consumes Carbon Dioxide and produces oxygen as a waste product.  In order for glucose to be produced, Carbon dioxide (a compound) must be, in essence, converted into a completely different chemical: dioxygen.

Photosynthesis is biochemical process by which green plants produce energy and release oxygen. Glucose is produced in this reaction and thus it is a chemical change. Thus, option D is correct.

What is a chemical change?

The change in a substance if involves any bond making or bond breaking then it is called a chemical change. Whereas, if the substance just changes from one phase or state to the other it is called a physical change.

All chemical reactions are chemical changes involving bond making or breaking or both. Photosynthesis is a biochemical reaction takes place in plant leaves with the aid of light energy.

Photosynthesis involves several stages where an electron transport chain, various oxidising and reducing agents are performing significant roles.

The net reaction in photosynthesis is the combination of water and carbon monoxide to form molecular oxygen and glucose. Therefore, there occurs bond making and breaking. Thus option D is correct.

What would happen if we couldn't carry respiration out?

Answers

Answer:

There would be no energy for cellular activities

Explanation:

Cellular respiration is the process whereby living organisms breakdown ingested food in their cells in order to obtain energy in form of ATP. In other words, respiration converts the stores energy in food molecules into usable energy by the cell. The general equation of the process is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

The process of cellular respiration is carried out by every living organism in order to obtain energy to perform their various metabolic activities. Hence, without RESPIRATION, there would be no energy (ATP) for use by the cell, which utterly means no cellular activities will take place.
