why is xenon monatomic but bromine is diatomic

Answer:

I believe the answer is false

Explanation:

Earth's gravity comes from all of its mass. All the mass makes a combined gravitational pull on all the mass in an object. If you were on a planet with less mass than Earth, you would weigh less than you do here. Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Mass is not the gravitational pull on the earth.

Hydrogen

Explanation:

An example of this can be In this example, hydrogen is the limiting reagent and oxygen is the excess reagent. The amount of product formed is limited by the amount of hydrogen.

Answer:

The frequency of the wave is 34 Hertz

Considering the reaction stoichiometry, the correct answer is second option: the total number of moles of water produced from 13. 35 mol of oxygen is 26.7 moles.

The balanced reaction is:

2 H₂ + O₂ → 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 1 moles of O₂ produce 2 moles of H₂O, 13.35 moles of O₂ will produce how many moles of H₂O?

[tex]amount of moles of H_{2} O=\frac{13.35 moles of O_{2} x2 moles of H_{2} O}{1 mole of O_{2}}[/tex]

amount of moles of H₂O= 26.7 moles

Finally, the correct answer is second option: the total number of moles of water produced from 13. 35 mol of oxygen is 26.7 moles.

All three elements  in the periodic table will for sure have characteristic of mass and volume.

An element  is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom which is characteristic of it's own. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Answer:

In a pure metal, the force needed to make the layers slide over each other is small. This explains why many pure metals are soft. ... The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide over each other.

Answer:

The differences in atmospheric pressure generate winds.

Explanation:

At the Equator, the sun warms the water and land more than it does the rest of the world. Warm equatorial air rises higher into the atmospher and migrates towards the poles. The complex relationships between fronts cause different types of winds and weather patterns.

The frequency of the X - ray is [tex]7.95 \times 10^{28} \ Hz[/tex].

The given parameters:

The frequency of the wave is calculated as follows;

[tex]E = hf\\\\f = \frac{E}{h} \\\\[/tex]

where;

Substitute the given parameters;

[tex]f = \frac{E}{h} \\\\f = \frac{5.27 \times 10^{-5} }{6.626 \times 10^{-34}} \\\\f = 7.95 \times 10^{28} \ Hz[/tex]

Thus, the frequency of the X - ray is [tex]7.95 \times 10^{28} \ Hz[/tex].

Desert environment will probably have the lowest relative humidity.

Relative humidity is a measure of water vapor content in the air. Desert environment will have the lowest relative humidity due to its high temperature and no availability of water bodies such as river, ocean etc so we can conclude that desert environment will probably have the lowest relative humidity.

Answer:

A pH calibration is the process of adjusting your pH meter by measuring solutions of a known pH value. This is because the characteristics of your electrode will change over time and this needs to be compensated for. A calibration does this by matching your pH meter to the current characteristics of your pH sensor.

O 7.94 x 10-8 M

Explanation:

Did the test

The hydronium ion concentration of a solution with a pOH of 6.90 is 7.94 × 10⁻⁸ M.

Relation between the pH and pOH will be represented by the below equation as:

pH + pOH = 14

Given that pOH = 6.90

So, pH = 14 - 6.90 = 7.1

Also we know that, pH = -log[H⁺]

[H⁺] = [tex]10^{-pH}[/tex]

[H⁺] = [tex]10^{-7.1}[/tex]M

[H⁺] = 7.94 × 10⁻⁸ M

Hence the concentration of hydronium ion is [tex]10^{-7.1}[/tex] M.

Answer:

211.0

Explanation:

∆G(free energy) = ∆H(enthalpy) - T∆S(entropy)

∆H = 215KJ/mol

T = 90°C = 273 + 90

= 363K

∆S = 11J/mol/K or 11 × 10^-3kJ/mol/K

∆G = 215- 363(11 × 10^-3)

= 215 - 3.993

= 211.007

To the nearest tenth 211.0
