Explain how metallic bonding supports the properties of metals

Answers

Answer 1

Answer:

Explanation: Because electrons are delocalized around positively charged nuclei, metallic bonding explains many properties of metals. ... Further, because the electrons are free to move away from each other, working a metal doesn't force together like-charged ions, which could fracture a crystal through the strong repulsion.

Answer:

C

Explanation

Because My teacher told me that for an example Florida is hot but in Central America is cold or hot and you don’t need a jacket. I don’t remember much

The Central America is near the equator could explain the above statement.

What is equator?

Equator is an imaginary line that passes through the centre of the globe at 0 degrees latitude and at equal distance between the North and South Poles.

Some countries of Central America are situated near the equator. The places near equator have little seasonal variation. These places have same amount of daylight and darkness throughout the year and remain warmer year round. These places near the equator have an alternating dry and rainy seasons.

Hence, we can conclude that option C is the answer.

An atom has 30 protons, 30 neutrons, and 30 electrons. What is the charge of the atom’s nucleus?
A: +30
B: +60
C: -30
D: -90

Answers

Answer:

+30

Explanation:

The nucleus holds both protons and neutrons. Since a neutron is neutral there is no charge. Protons are a positive charge. so the atoms nucleus is +30.

The charge on an atom's nucleus is the same as the number of protons in the nucleus. The charge on the nucleus of the atom is +30.

The nucleus houses positive particles called protons. Each proton carries a charge of +1.

The magnitude of charge of the nucleus is the same as the number of protons in the nucleus.

Since there are 30 protons, the magnitude of  charge of the nucleus is expected to be + 30.

The half-life of a radioisotope

a
gets shorter with time

b
is constant

c
get shorter with increasing temperature

d
decreases by a factor of two each time
e
become longer over time

Answers

Answer:

b  is constant

Explanation:

The half-life of a radioisotope is constant throughout its life cycle.

Half-life is the time taken for half of the radioactive nuclei to disintegrate.

Every radionuclide has its characteristic half-life and it is independent of the number of radioactive atoms.

The half-life does not depend on any variable. It is an inherent property of a radioactive isotope. The shorter the half-life, the faster a radionuclide decays. Nuclides with a long half life are fairly stable for a long period of time. The decay of a radioactive element is usually characterized by its half-life.

Therefore, the most ideal statement about half-life is that it is constant.

1. A student measures the height of a small lamp to be 32cm. According to the factory specifications,
the lamp is actually 30cm. What is the percent error of the student's measurement?

Answers

Answer:

6.67 %

Explanation:

Given that,

Measured height of a small lamp, l = 32 cm

Actual height, l' = 30 cm

We need to find the percent error of the student's measurement. Percent error is given by :

[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]

Putting all the values, we get :

[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]

So, the percent error of the student's measurement is 6.67 %.

The molar absorptivity of a compound at 500 nm wavelength is 252 M-1cm-1. Suppose one prepares a solution by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution. What would be the absorbance in a 3 .00 mm pathlength cell?

Answers

Answer:

The absorbance of the solution is 0.21168.

Explanation:

Given that,

Wavelength = 500 nm

Molar absorptivity = 252 M⁻¹ cm⁻¹

Number of moles = 0.00140

Volume of solution = 500.0 mL

Length = 3.00 mm

We need to calculate the molar concentration

Using formula of the molar concentration

[tex]C=\dfrac{N}{V}[/tex]

Where, N = number of moles

V = volume

Put the value into the formula

[tex]C=\dfrac{0.00140}{0.5000}[/tex]

[tex]C=0.0028\ M[/tex]

We need to calculate the absorbance of the solution

Using formula of absorbance

[tex]A=\epsilon C l[/tex]

Put the value into the formula

[tex]A=252\times0.0028\times0.300[/tex]

[tex]A=0.21168[/tex]

Hence, The absorbance of the solution is 0.21168.

The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.

First, we will calculate the molarity of the compound, which is equal to the moles of solute divided by the liters of solution.

[tex]M = \frac{0.00140mol}{0.5000L} = 0.00280 M[/tex]

Then, we will convert 3.00 mm to cm using the conversion factor 1 cm = 10 mm.

[tex]3.00 mm \times \frac{1cm}{10mm} = 0.300 cm[/tex]

Finally, we will calculate the absorbance of the compound using the Beer–Lambert equation.

[tex]A = \epsilon \times b \times C[/tex]

where,

A: absorbanceε: molar absorptivityb: length of light pathC: molar concentration

[tex]A = \epsilon \times b \times C = \frac{252}{M.cm} \times 0.300 cm \times 0.00280 M = 0.212[/tex]

The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.

At present, fusion reactions... Group of answer choices produce the energy in some nuclear power plants. cannot be used to produce energy in reactors. produce the energy in all recent nuclear power plants. produce the energy in most nuclear power plants.

Answers

Answer:

cannot be used to produce energy in reactors.  

Explanation:

Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.

Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

List the following elements in order of increasing atomic radius:
1. sulfur II. hydrogen III. strontium IV. iodine
V. oxygen

Answers

Answer:

sulfur

hydrogen

iodine

oxygen

strontium

Explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.

Order of increasing atomic radius:

O < H < S < I < Sr

Describe the trend of atomic radius.

The atomic radius measures the separation between an atom's nucleus and its farthest electrons.

The trend across a periodAtoms' atomic radii typically decrease from left to right.As electrons are added to the same primary energy level, protons are gradually added to the nucleus. Because of the increased positive charge on the nucleus, these electrons are gradually drawn closer to it. Atomic sizes shrink as the strength of attraction between nuclei and electrons grows.

The trend down the groupWithin a group, atoms' atomic radii typically increase from top to bottom. Again, the positive nuclear charge rises as the atomic number decreases inside a group. The number of major energy levels that are occupied is increasing as well, though. The orbitals from higher primary energy levels have greater sizes than the orbitals from lower principal energy levels. Atomic radius increases down a group as a result of the stronger impact of the major energy levels outweighing the increase in nuclear charge.
