What are the 4 properties of substances that contain Hydrogen Bonds?

Answer:

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g

2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂

Molar mass of Fe = 56 g/mole

Mass of Fe from the balanced equation = 2 × 56 = 112 g

Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole

Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g

SUMMARY

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

Therefore,

1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃

Thus, 5792.44 g of Fe(NO₃)₃ were obtained from the reaction

Answer:

We assume that there is 100g of the compound (because it makes it easier to calculate) and we turn the percentages into grams.

2% of Hydrogen = 2g of H

32.7% of Sulfur = 32.7g of S

65.3% of Oxygen = 65.3g of O

Now we change the mass of these elements to moles by dividing the mass by the molar mass (which is the value of atomic mass on your periodic table)

2g/1.01g = 1.98 mol

32.7g/32.06g = 1.02 mol

65.3g/16g =4.08 mol

divide all these mol values by the smallest mol value, which is 1.02. (Round the values to whole numbers)

1.98/1.02 = 2 (rounded) of Hydrogen

1.02/1.02 = 1 of Sulfur

4.08/1.02 = 4 of Oxygen

H2SO4 (also known as sulphuric acid) is your empirical formula.

Considering the ideal gas law, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

In this case, you know:

Replacing:

2 atm× V = 4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K

Solving:

V = (4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K)÷ 2 atm

V= 68.67 L

Finally, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Explanation:

Answer:

8 electrons.

Explanation:

Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈1.00794amu≈1amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1−1=0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

another way of explaining:

The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons

Answer:

Thermal energy consists of the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is related to heat and temperature.

Explanation:

To solve for number one we must follow these steps:

m = 703.55 g − 345.8 g

m = 357.75 g

Then we solve for the density-

d = 357.75 g / 225 mL

d = 1.59 g/mL

Answer for number 5) 1.59 g/mL

Density= Mass/Volume

therefor- Mass = 65.14g and Volume = 35.4mL

Density = 65.14g/35.4 mL = 1.84 g/mL

Answer for number 6) 1.84 g/mL

Question 7-

g = (0.8765 g/mL)(250.0 mL) = 219.1 g

Answer: 219.1 g

Question 8-

Density = mass/volume

Mass = 1587g

4.5cm x 5.2cm x 6cm = 140.4 cubic-cm

Volume = 140.4 cubic-cm

Mass/volume = 1587/140.4 = 11.3 g/cm^3

Answer: 11.3 g/cm^3

Question 9:

First calculate the volume of iron

49.10mL − 45.50mL = 3.60mL

Density = mass/volume;

density = 28.5g/3.60 mL= 7.92 g/mL

Answer: 7.92 g/mL

Question 10:

Volume = 2500.0g / 10.5g/cm3 = 238.095cm^3

Now we round up the answer to 238cm^3

Answer: 238cm^3
