What is the “Island of Stability”?

Answers

Answer 1

Answer:

The island of stability is a term from nuclear physics that describes the possibility of elements with particularly stable "magic numbers" of protons and neutrons. This would allow certain isotopes of some transuranic elements to be far more stable than others, that is, decay much more slowly.

An avocado has a mass of 215 g and a density of 0.86
g/mL. What is the volume of the avocado?

Answers

density = mass/volume
.86 = 215/volume
.86(volume) = 215
volume = 250

The volume of avocado here is 250 ml as per the given data i.e., mass of 215 g and a density of 0.86 g/mL.

What is density?

The density of an artifact is delineated as its mass divided by the volume. Density is commonly expressed in grams per cubic centimeter.

The grams are a unit of mass and indeed cubic centimeters are a unit of volume. A box with more particles will be denser than a box with fewer particles.

The density of a solid, liquid, or gas illustrates how closely packed the particles can be. The amount of mass per unit volume is defined as density.

Density is defined as d = M/V, where d is density, M is mass, and V is volume. Density is commonly measured in grams per cubic centimetre.

We know that,

Density = mass/volume.

Volume = mass/density.

Here, it is given that

Density = 0.86 g/mL.

Mass = 215 g.

Volume = 215/0.86 mL.

Volume = 250 mL.

Thus, the answer is 250 mL.

How many moles of carbon are in 7.00 x 1023 atoms of carbon?

Answers

Answer:

1.16 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{7 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{7}{6.02} \\ = 1.162790....[/tex]

We have the final answer as

A gram of gasoline produces of energy when burned. Gasoline has a density of . How would you calculate the amount of energy produced by burning of gasoline

Answers

Answer:

1.66x10⁶kJ of energy are produced

Explanation:

...Produces 45kJ... Has a density of 0.77g/mL... By burning 48L of gasoline...

To solve this question we need to calculate the mass in grams of gasoline in 48L using its density.

With the mass and knowing 1gram produces 45kJ of energy we can find the energy produced by burning 48L of gasoline, thus:

mL of gasoline:

48L * (1000mL / 1L) = 48000mL of gasoline

g of gasoline:

48000mL * (0.77g/mL) = 36960g of gasoline

Energy produced:

36960g of gasoline * (45kJ / g) =

1.66x10⁶kJ of energy are produced

From the question given above:

We are to find the sum of:

4x³ + 2x² – 4x + 3 and 7x³ – 4x² + 7x + 8

To add the above polynomials together we must recognise that we can only add like terms together. The sum of the above polynomials can be obtained as follow:

Number of mole of O₂ = 22.63 moles

Volume of O₂ =?

Recall:

1 mole of a gas occupy 22.4 L at STP.

With the above information, we obtained the volume occupied by 22.63 moles of O₂ as follow:

1 mole of O₂ occupied 22.4 L at STP.

Therefore, 22.63 moles of O₂ will occupy = 22.63 × 22.4 = 506.912 L at STP.

Thus, 22.63 moles of O₂ is equivalent to 506.912 L.

In this case, since the Fischer esterification stand for the organic acid-base reactions, we infer that the alcohol is related to the -yl part on the name (ethyl propanoate) as the alcohol is likely to lose the -OH and provide a carbocation for the carboxyl group of the carboxylic acid.

In such a way, since the -yl part is given as ethyl, we infer the used alcohol is ethanol:

Consider the production of sulfur trioxide from sulfur dioxide and oxygen gas:How many grams of sulfur dioxide reacted if 163 kilojoules of heat were evolved in an experiment

Answers

Answer:

102.4 g

Explanation:

The equation of the reaction is;

2SO2(g) + O2(g) -----> 2SO3(g) --------ΔH = -198 KJ/mol

Now, given that;

If 2 moles of SO2 evolves 198 KJ/mol of heat

x moles of SO2 evolves 163 KJ/mol of heat

x = 2 * 163/198

x = 1.6 moles of SO2

molar mass of SO2 = 64 g/mol

mass of SO2 = 1.6 moles * 64 g/mol = 102.4 g

Energy absorbed (Q): 4430 JMass of water (m): 237 gSpecific heat of water (c): 4.186 J/g.°C

Step 2: Calculate the temperature change

We will use the following expression.

Q = c × m × ΔT

ΔT = Q / c × m

ΔT = 4430 J / (4.186 J/g.°C) × 237 g

ΔT = 4.46 °C

The temperature change is 4.46 °C.

Which wave can travel in both empty space and matter?
(10 Points)
A. radio
B. seismic
C. sound
D. water

Answers

I believe Choice B is the answer.

Seismic waves can move through both empty space and matter. Electromagnetic waves differ from sound waves in this regard because they do not require molecules to move.

What are earthquake waves?Seismic waves are waves that pass through or over the Earth. They can also be caused by explosions, volcanoes, landslides, and earthquakes, which are movements of the Earth's tectonic plates. They can reveal a lot about the Earth's composition. Earthquakes are caused by sudden movement along Earth's fault lines. Seismic waves, which cause damage by traveling through the Earth, are created when movement releases energy from the "elastic strain" that has been stored.This means that electromagnetic waves can travel through solid materials like air as well as across space. Astronauts use radios in this manner to communicate while on spacewalks. Radio waves are an example of an electromagnetic wave.

what is this element

Answers

Answer:

Oxygen

Explanation:

From the question given above, the following data were obtained:

Number of electrons = 8

Number of protons = 8

Number of Neutrons = 8

Name of element =?

Next, we shall determine the atomic number of the element. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically, it is expressed as:

Atomic number = proton number

From the question given above,

Number of protons = 8

Therefore,

Atomic number = 8

Comparing the atomic number of the element (i.e 8) with those in the periodic table, we can conclude that the element is oxygen since no two elements have the same atomic number.
