In the process of ionization, what is the relationship between the second ionization energy and the third ionization energy?

Answers

Answer 1
Answer:  The first ionization energy is the energy it takes to remove an electron from a neutral atom. The second ionization energy is the energy it takes to remove an electron from a 1+ ion. (That means that the atom has already lost one electron, you are now removing the second.) The third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) 
And 2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth.

A student adds a tablespoon of sugar to a glass containing tea and ice cubes. The mixture is then stirred until all the sugar dissolves. Which observation is a clue that the student's final mixture is heterogeneous
A. Some ice cubes are floating in the tea
B. The sugar crystals are no longer visible in the tea
C. The mixture looks the same throughout
D. Some water droplets form on the outside of the glass
The subject is science

Answers

Answer:

The correct option is;

A. Some ice cubes are floating in the tea

Explanation:

A heterogenous mixture is one that is made up of more than one clearly identifiable phase of matter (such as solid and liquid, liquid and gas, gas and solid, or solid, liquid and gas combined) and therefore having non-uniform composition, which varies from one section to another within the mixture.

Ice cubes which are solids being observable on the surface of the mixture provides clue that the student has made an heterogenous mixture.

Physical activity and exercise typically lead to __________.a. increased stress
b. depression
c. higher energy levels
d. reduced quality of life

Answers

The answer is c - physical activity and exercise typically lead to higher energy levels. The endorphins and hormones released during periods of high activity actually help to combat stress and depression linked to a depletion in serotonin, and therefore can only increase the quality of life. The other possible answers to this question are therefore all incorrect.

the answer is c i just took the test

Whether an ionic bond or a covalent bond forms, bonds form in order to make newly created substances ________ than the substances they were created from.a. less stable
b. more stable
c. less efficient
d. more efficient

Answers

I am sure the correct answer is B. Bonds are formed in order to make substances more stable than their former. Every process in this world works in order to achieve equilibrium or to be in a stable state this includes chemical reactions. Unstable substances will always find a way to become stable because it is the state with minimum energy.

Given the balanced equation:2C + 3H2==> C2H6
What is the total number of moles of C that must completely react to produce 2.0 moles of C2H6?
(1) 1.0 mol (3) 3.0 mol
(2) 2.0 mol (4) 4.0 mol

Answers

Answer: The correct answer is option 4.

Explanation:

2C+3H_2\rightarrow C_2H_6

According to the reaction, 1 mol of C_2H_6 is obtained from 2 moles of C gives

Then, 2 moles of C_2H_6 will be obtained from:

(2)/(1)* 2 moles of C =4 moles

Hence, the correct answer is option 4.

The answer is (4) 4.0 mol. This is a stoichiometry problem. You start with 2.0 mol of C2H6 and obtain the moles of C by multiplying 2.0 by the mole ratio, in this case 2. 2.0*2=4.0mol.

An atom of titanium has an atomic number of 22 and a mass number of 49. Calculate the number of protons and neutrons in this atom. If the atom of titanium is neutral, how many electrons are in the atom?

Answers

If an atom of titanium has the mass number of 49, then the atom is comprised of 49 protons and neutrons. Since it’s atomic number is 22, we know that it has 22 protons. This means that there are 27 neutrons in the nucleus (49-22).

If the atom is neutral, then the number of protons equals the number of electrons. Therefore, there are 22 electrons in a neutral titanium atom.

Protons: 22
Neutrons: 27
Electrons: 22

Final answer:

An atom of titanium with atomic number 22 and mass number 49 contains 22 protons, 27 neutrons, and 22 electrons.

Explanation:

An atom of titanium has an atomic number of 22 and a mass number of 49. The atomic number represents the number of protons in an atom, so there are 22 protons in this titanium atom. The mass number of an atom is the sum of its protons and neutrons.

Since the atomic mass is 49, and the atomic number is 22, we can subtract the atomic number from the atomic mass to find the number of neutrons. In this case, there are 27 neutrons in the titanium atom. If the titanium atom is neutral, it means it has an equal number of protons and electrons. Since there are 22 protons, there are also 22 electrons in the atom.
