How much space does 2 x 10^22 atoms of copper take up?

Answers

Answer 1

Answer:

2.35mL

Explanation:

The amount of space a substance holds is its volume.

Density = mass (g) /volume (L)

Where;

mole = mass/molar mass

Since 1 mol of Cu contains 6.022 × 10^22 atoms.

There are 2 x 10^22/6.022 × 10^22 moles in 2 x 10^22 atoms of copper

2 x 10^22/6.022 × 10^22

2/6.022 × 10^(22-22)

0.332 × 10^0

0.332mol

Mole = mass/molar mass

0.332 = mass/63.5

mass = 63.5 × 0.332

mass = 21.08g

Density = mass/volume

Density of copper (Cu) is 8.96 g/cm³

8.96 = 21.08/v

V = 21.08/8.96

V = 2.35mL or cm³

In science class, a student is given a copper cylinder to investigate. The student measures the mass of the cylinder as 53.76 grams. The
student measures the volume of the copper as 6 cm. Which additional property of the copper can the student determine from these
measurements?

Answers

Answer:

From these two values, i.e. mass and volume, density of the copper cylinder can be calculated.

Formula of density is :

Density = Mass / volume.

Now we have mass: 53.76g and volume 6cm³

Density = 53.76 / 6

Density= 8.96 g/cm³

You will learn in this course that organic compounds have covalent bonds with a significant amount of energy stored in them. This is why we burn fossil fuels to generate energy to heat our homes or drive our cars. Given this information, which of the compounds listed below would you expect to have the most energy is its carbon-carbon bond?

Answers

Answer:

See explanation

Explanation:

This question is obviously supposed to be a multiple choice question but the options are missing.

However, the question intends to test the student's knowledge about combustion of fossil fuels. Fossil fuels are mostly composed of hydrocarbons of different chain lengths.

The longer the chain length, the greater the energy released when the compound is burnt since there are more energy stored in its bonds.

Hence, the correct answer to this question will be the option that contains the greatest number of C-C and C-H bonds.

A metal object has a density of 2 g/ml. When placed in a graduated cylinder with 500 ml of water, the
water rises to 508 ml. What is the mass of the metal object?

Answers

Answer:

The answer is 16 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 2 g/ml

volume = final volume of water - initial volume of water

volume = 508 - 500 = 8 mL

We have

mass = 2 × 8

We have the final answer as

16 g

Why do atoms share electrons in covalent bonds?

A. to attain a noble-gas electron configuration

B. to become more polar

C. to become ions and attract each other

D. to increase their atomic numbers​

Answers

Answer:

Answer Option A) To attain a noble-gas electron configuration.

Explanation:

Correct answer from test

Taking into account the definition of covalent bond and octet rule, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

The covalent bond is the chemical bond that occurs between atoms of non-metallic elements. These atoms have many electrons at their outermost level and have a tendency to share them to acquire the stability of the noble gas electronic structure. In this way a molecule is formed.

The tendency of the elements to reach a stable configuration is known as the octet rule. For this, the octet rule explains that there must be eight electrons in their last energy levels, thus acquiring the structure of a noble gas.

So, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule in order to comply with the octet rule.

Finally, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

Answer:

Which indicates that thermal energy is no longer being transferred from boiling water to a mug?

The mug and the water lose all thermal energy.

The water is hotter than the mug.

The mug is hotter than the water.

•The water and the mug are the same temperature.

Explanation:

answer #D is correct

When the water and the mug are at the same temperature then thermal energy will no longer be transferred from the boiling water to the mug. Therefore, option (D) is correct.

What is thermal energy?

Thermal energy is generated in a substance when an increase in temperature causes atoms and molecules to move at a faster speed and result in the molecules colliding with each other. The energy generated from the temperature of the heated material is called thermal energy.

Thermal Energy or internal kinetic energy is because of the random motion of molecules in the system. The thermal energy of any system is directly proportional to its temperature.

The more the temperature of the system, the more the movement of molecules within a given system, and the more the thermal energy of the system.

The thermal energy will be transferred from the boiling water to the mug when the water is hotter than the mug. When both have the same temperature then the thermal energy is no longer being transferred from boiling water to a mug.

A student observes that instant tea dissolves more rapidly in a cup of 250 mL of stirred hot water than in a cup of 250 mL of stirred cold water. Which is the most relevant hypothesis that the student could develop based on this observation?

A.
Volume affects the rate that instant tea dissolves in a solvent.
B.
Temperature affects the rate that instant tea dissolves in water.
C.
Stirring affects the rate that instant tea dissolves in water.
D.
Pressure affects the rate that instant tea dissolves in water.

Please answer my question!

Answers

Answer:

B

Explanation:

In this question, there is no mention of pressure, so we can eliminate answer D. In both cups, it mentions they contain 250 mL of water and both are stirred, so these would be constants. The only difference between the cups is temperature, so temperature must affect the rate that instant tea dissolves in water. Therefore the answer is B.
