How does an element differ from a compound

Answers

Answer 1

Answer: Elements are one , but compound is elements all together to form something.

Answer 2

Answer:

-_- Compounds n Elements -_-

A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds.

When the elements are joined, the atoms lose their individual properties and have different properties from the element they are composed Of .

Consider this molecular‑level representation of a mixture of gases. There are three gas particles containing two spheres. There are six gas particles containing a single sphere of a different color. There are five gas particles containing a single sphere of a third color. If the partial pressure of the diatomic gas is 0.330 atm, what is the total pressure?

Answers

The total pressure of the gaseous mixture is 1.57 atm.

The mixture of the gases consists of 3 diatomic molecules, 6 monoatomic molecules, and 5 other monoatomic molecules.

The total number of molecules in the mixture are:

$\rm Total\;molecules\;=\;3+6+5\nTotal\;molecules\;=\;14$

Computation for the total pressure of the gas

The total pressure of a gas by Raoult's law is given as:

$\rm Total\;pressure=(Partial\;pressure)/(Mole\;fraction)$

The partial pressure of the diatomic gas is 0.330 atm.

The mole fraction of the diatomic gas is given as:

$\rm Mole\;fraction=(Molecules\;of\;diatomic\;gas)/(Total\;molecules) \n\nMole\;fraction=(3)/(14)\n\n Mole\;fraction=0.2$

The mole fraction of the diatomic gas is 0.2.

The total pressure of the gas is given as:

$\rm Total\;pressure=(0.330)/(0.2)\;atm\n\n Total\;pressure=1.57\;atm$

The total pressure of the gaseous mixture is 1.57 atm.

Explanation:

The given data is as follows.

Number of particles of diatomic gas = 3

Number of particles of monoatomic gas = 6

Number of particles of another monoatomic gas = 5

Therefore, total number of particles or moles present will be as follows.

3 + 6 + 5 = 14

As we know that, mole fraction = $\frac{\text{moles of given substance}}{\text{total no. of moles}}$

Hence, more fraction of the diatomic gas will be as follows.

mole fraction = $\frac{\text{moles of given substance}}{\text{total no. of moles}}$

= $(3)/(14)$

= 0.21

Now, formula to calculate partial pressure will be as follows.

Partial pressure of one species = molar fraction of that species x total pressure

Therefore, $P_(diatomic) = \text{mole fraction diatomic} * P_(total)$

$P_(total) = (0.330 atm)/(0.21)$

= 1.57 atm

Thus, we can conclude that total pressure is 1.57 atm.

If i add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be ?

Answers

Taking into account the definition of dilution, the molarity of the diluted solution is 0.125 M.

Dilution

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentration
Vi: initial volume
Cf: final concentration
Vf: final volume

Final molarity

In this case, you know:

Ci= 0.15 M
Vi= 125 mL
Cf= ?
Vf= 125 mL + 25 mL= 150 mL

Replacing in the definition of dilution:

0.15 M× 125 mL= Cf× 150 mL

Solving:

(0.15 M× 125 mL)÷ 150 mL= Cf

0.125 M= Cf

In summary, the molarity of the diluted solution is 0.125 M.

Answer:

0.125 M

Explanation:

M₁V₁ = M₂V₂

125 mL / 1000 = 0.125 L = V₁

25 + 125 = 150 mL / 1000 = 0.150 L = V₂

0.15 M = M₁

M₁ × V₁ / V₂ = M₂

(0.15) × (0.125) / (0.150) = 0.125 M

0.125 M is the answer

If an excess of sulfric acid reacts with 23.0 grams of sodium chloride how many grams of hydrochloric acid are produced? 2H2SO4 + 4NaCI -> 2H2SO4 + 4HCI

Answers

NaCl = 58.44 g/mol
H₂SO₄ = 98.0 g/mol

H₂SO₄ + 2 NaCl = 2 HCl + Na₂SO₄

98.0 g H₂SO₄ -----------> 2 x 58.44 g NaCl
? g H₂SO₄ ------------> 23.0 g NaCl

Mass of H₂SO₄ = 23.0 x 98.0 / 2 x 58.44

Mass of H₂SO₄ = 2254 / 116.88

=> 19.284 g of H₂SO₄

Need a correct answer fastHow many moles of solute are contained in a 500.0 milliliter solution that has a concentration of 0.35 M?

Answers

There would be 0.175 moles of solute contained in a 500.0 milliliter solution that has a concentration of 0.35 M.

Let x be the number of moles
Since the equation is moles/liters=molarity, change 500 mL to liters:
500.0 mL=0.5L
Divide:
x/0.5L = 0.35M
Cross multiply: x=0.35*0.5
x=0.175 moles
