– Why could a flight from California to New York be shorter than a flight from New York to California?

Answers

Answer 1

Explanation: Honestly, I have no idea and I've never learned this, but I think it's because of air resistance and currents? Going downwind would mean the plane's rate would be the speed of the wind + the speed of the plane itself. Going upwind, the plane's rate would be the speed of the plane - the speed of the wind. Thus, going one way (e. g. California to New York) could take less time than going the other way.

Two students were conducting and experiment based on the ionization energy of alkali metals. The driving question for the experiment was: "What is the relationship between ionization energy and the rate of reaction (time for the reaction to be completed) using alkali metals."



Which of the following predictions would be the best option based on the student's prior knowledge learned and information provided in the graph above?

A.
Cesium will have a higher rate of reaction (faster) because it has the lowest ionization energy which indicates a higher reactivity.

B.
Cesium will have a lower rate of reaction (slower) because it has the lowest ionization energy which indicates a lower reactivity.

C.
The ionization energy of the alkali metals will not affect the rate of the reaction because the energy required to remove an electron does not affect time.

D.
Lithium will have a higher rate of reaction (faster) because it has the highest ionization energy which indicates a higher reactivity.

Answers

Answer:

A

Explanation:

Cs has a higher rate of reaction because it's easier to remove an electron from it, thereby leading to faster reactivity

How many grams of sodium chloride decompose to yield 15 grams of chlorine gas?
2NaCl → 2Na+ Cl2
A- 12.363 9 Naci
B- 49.453 g Naci
C- 30 g NaCl
D- 0.846 g Naci

Answers

Answer:

24.6g of NaCl

Explanation:

Expression of the reaction:

            2NaCl →  2Na  +  Cl₂

Given parameters:

Mass of Cl₂  = 15g

Unknown:

Mass of NaCl  = ?

Solution:

To solve this problem, we have to use mole relationships.

 Find the number of moles of the mass of the given specie;

    Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

     Molar mass of Cl₂  = 2(35.5) = 71g/mol

   Number of moles  = [tex]\frac{15}{71}[/tex]   = 0.21mole

Now;

 From the balanced reaction equation;

        1 mole of Cl₂ is produced from 2 moles of NaCl;

      0.21 mole of Cl₂ will be produced from 0.21 x 2 = 0.42mole of NaCl

So,

  Mass of NaCl = number of moles x molar mass

    Molar mass of NaCl  = 23 + 35.5 = 58.5g/mol

 Mass of NaCl  = 0.42 x 58.5 = 24.6g of NaCl

Answers

Answer:

YES

the main reason why bonds form is because the elements wants to be more stable so in a covalent bond the electrons are shared between two elements so they can fulfill or at least "feel" like they have fulfilled there outer shell.

How might emission spectra be used in studying stars?

Answers

Answer:

Emission spectra may be used in studying stars in order to determine what atoms makeup the individual star produces, due to the fact that each atom’s emission spectra biunique, one can observe the spectra emitted by the star and identify the atoms that are released by the light the star produces.

The emission spectrum can tell the elements present in the source of light. Therefore, this method can be used to get information about the element present in the stars.

What is the emission spectrum?

Electromagnetic radiations interact with atoms or molecules of matter, the electrons absorb energy and jump to a higher energy state of atoms by losing their stability.

They need to move from the higher energy state to the lower energy level to regain their stability. These atoms or molecules emit radiations in several regions of the electromagnetic spectrum. The spectrum of radiation emitted by electrons in the excited state is called the emission spectrum.

The emission spectrum of a chemical element is the spectrum of frequencies of electromagnetic radiation emitted when an atom transitions from a high-energy state to a lower-energy state. The emitted energy is unique for every element and is the characteristic of the element.
