what is the ionization energy of a hydrogen atom if the electron is in its ground state? =1.09678×10−2 nm−1 r=1.09678×10−2 nm−1 ionization energy

Answers

Answer 1

The ionization energy of a hydrogen atom in its ground state is 13.6 electron volts (eV) or 1.09678×10−2 nm−1.

This energy is the amount of energy required to remove the electron from the hydrogen atom when it is in its lowest energy state, or ground state. When the electron is removed, the hydrogen atom becomes a positively charged ion. The ionization energy of a hydrogen atom is important in understanding the behavior of atoms and molecules in chemical reactions and in many other areas of physics and chemistry. It is also used in calculating the energy levels of other atoms and molecules, and in determining the properties of materials such as metals and semiconductors.

Overall, the ionization energy of a hydrogen atom is a fundamental property of matter that has important implications in many areas of science.

Wendy wants to find out if a substance is an acid or a base. What are two ways that Wendy could
investigate to find out what kind of substance it is?

Answers

If it is corrosive and sour, or bitter and smooth. Or, by its pH level.

Without tasting a colorless liquid, an acid or a base can be determined using indicators.

The three most common indicators to test for acids and bases are: Litmus. Methyl orange. Phenolphthalein.

How do you know something is an acid?One practical method for determining how acidic something is is to use the pH scale. A solution is acidic if its pH is less than 7. If the pH of the solution is 7, it is neutral; if the pH is greater than 7, it is basic.To identify acids and bases, two types of litmus paper are available: red litmus paper and blue litmus paper. When exposed to acidic conditions, blue litmus paper turns red, while red litmus paper turns blue when exposed to basic or alkaline conditions.

Why Doesn't The Earth Usually Feel Solar Winds?

Answers

Answer:

When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.

How does the temperature of the air change with altitude?

Answers

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

what creates an electric current in a battery?

A. Atoms dissolving
B. Metals generating
C. Electrons jumping
D. Liquids moving ​

Answers

Answer:

There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.

Explanation:

option (B) is right

Metals used in batteries undergo a chemical reaction with the electrolyte and free the electrons. The flow of electrons produces the electric current.

What is the electrical battery?

An electric battery can be described as a source of electric power containing of one or more electrochemical cells with external connections.

The positive terminal of the battery is the cathode and its negative terminal is the anode. The negative terminal can be denoted as the source of electrons that will flow via an external electric circuit to the positive terminal.

A redox reaction transforms high-energy reactants into lower-energy products, and the free-energy difference provides the external circuit as electrical energy.

Each cell of the battery contains two half-cells connected in series by an electrolyte containing metal cations. One half-cell includes an electrolyte and the negative electrode and the other half-cell includes an electrolyte and the positive electrode. Cations are reduced at the cathode, while metal atoms are oxidized at the anode.

How many grams of magnesium oxide would be produced if 3.8 grams of magnesium reacted completely with 2.1 grams of oxygen

Answers

Answer:

5.3g of MgO would be produced

Explanation:

Based on the chemical reaction:

2Mg(s) + O₂(g) → 2MgO(s)

1 mole of Mg reacts per mole of oxygen.

To solve this question we need to convert the mass of each reactant to moles in order to find limiting reactant using the chemical equation:

Moles Mg -Molar mass: 24.305g/mol-:

3.8g Mg * (1mol / 24.305g) = 0.1563moles Mg

Moles O₂ -Molar mass: 32g/mol-:

2.1g O₂ * (1mol / 32g) = 0.0656 moles O₂

For a complete reaction of 0.0656 moles of O₂ are required:

0.0656 moles O₂ * (2 mol Mg / 1mol O₂) = 0.132 moles Mg

As there are 0.1563 moles of Mg, Mg is the excess reactant and O₂ the limiting reactant.

0.0656 moles O₂ produce:

0.0656 moles O₂ * (2 mol MgO / 1mol O₂) = 0.132 moles MgO

The mass is -Molar mass MgO: 40.3g/mol-:

0.132 moles MgO * (40.3g / mol) =

5.3g of MgO would be produced

2. Calculate the wavelength of a space shuttle with a mass of 2.05 x 107kg traveling at a rate of 7.85 x 103 m/s. ​

Answers

Answer:

See explanation

Explanation:

1) With the advent of the quantum theory came the idea that the path of a moving electron can not be exactly determined. We can only talk about the probability of finding the electron within a given region in space.

2) Using the De Broglie's relation;

λ = h/mv

Where;

λ = wavelength

h = Plank's constant

m = mass

v = velocity

λ = 6.6 * 10^-34/2.05 x 10^7 * 7.85 x 10^3

λ = 4.1 * 10^-25 m
