Give the number of covalent bonds in Xenon and phosphorus

12. Draw an energy curve for a chemical reaction that begins at 30 kj and has an activation energy of

Rufina [12.5K]

Answer:

Since the activation energy is $50kJ$ , we need to supply it $50kJ$ from $30kJ$ to make it $80kJ$ .

How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution

Ganezh [65]

Answer:

0.01932 L

Explanation:

First we convert 105 mM to M:

105 mM / 1000 = 0.105 M

Next we convert 552 mL to L:

552 mL / 1000 = 0.552 L

Then we use the following equation:

C₁V₁=C₂V₂

Where:

C₁ = 3 M

V₁ = ?

C₂ = 0.105 M

V₂ = 0.552 L

We input the given data:

3 M * V₁ = 0.105 M * 0.552 L

And solve for V₁:

V₁ = 0.01932 L

1. We have new knowledge of how charge can be transferred from one object to another

NeX [460]

Charge can be transferred from one object to another in three way conduction, polarization, and friction

Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)

Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

It is observed that the atoms of hydrogen in gas discharge tube emit radiations whose spectrum shows line characteristics (line

azamat

Answer: the line Spectra of hydrogen lies between the ultra-violet, visible light and infra-red of the electro magnetic spectrum

Explanation:

Electromagnetic radiation spans an wide range of wavelengths and frequencies. This range is called the electromagnetic spectrum. The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The 7 regions includes; radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

lower-energy radiation, such as radio waves, is expressed as frequency while microwaves, infrared, visible and UV light are usually expressed as wavelength and finally, higher-energy radiation such as X-rays and gamma rays, is expressed in terms of energy per photon.

Therefore, hydrogen lies between the ultra-violet, visible light and infra-red region of the electro magnetic spectrum.
