Answer:

the concentration of hydrogen iodide will be higher than it was in the original equilibrium conditions.

Answer: The molarity of given solution is 0.0235 M.

Explanation:

Given : Volume of solution = 511 mL

Convert mL into L as follows.

[tex]1 mL = 0.001 L\\511 mL = 511 mL \times \frac{0.001 L}{1 mL}\\= 0.511 L[/tex]

Mass of [tex]NH_{3}[/tex] (solute) = 205 mg

Convert mg into gram as follows.

[tex]1 mg = 0.001 g\\205 mg = 205 mg \times \frac{0.001 g}{1 mg}\\= 0.205 g[/tex]

As molar mass of [tex]NH_{3}[/tex] is 17 g/mol. Hence, number of moles of [tex]NH_{3}[/tex] are calculated as follows.

[tex]No. of moles = \frac{mass given}{molar mass}\\= \frac{0.205 g}{17 g/mol}\\= 0.012 mol[/tex]

Molarity is the number of moles of a solute dissolved in a liter of solution.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}[/tex]

Substitute the values into above formula as follows.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\= \frac{0.012 mol}{0.511 L}\\= 0.0235 M[/tex]

Thus, we can conclude that the molarity of given solution is 0.0235 M.

Answer:

Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water's hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

Answer:

I think A

Explanation:

Grams are the unit of weight or the mass that is the multiplication of the moles and the molar mass of the substance. The mass of hydrogen gas produced is 6.06 gm.

Mass is calculated in grams by multiplying the number of moles of the substance and the molar mass of the given molecule or compound.

Given,

Moles (n) of hydrogen = 3 mol

Molar mass of dihydrogen = 2.007 g/mol

Mass is calculated as:

[tex]\begin{aligned} \rm Mass &= \rm moles \times molar\; mass\\\\&= 3 \times 2.007\\\\&= 6.06\; \rm gm\end{aligned}[/tex]

Therefore, option D. 6.06 gm is the mass of hydrogen gas.

Answer:

115 mL of a gas is at 45.8 kPa and 57.2°C. What is the volume of the gas at 99.3 kPa and 112.3°C?[5] 11. ... What is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of 35,000 mL at standard temperature?

Explanation:

By using gas law , the volume will be 61.9 mL .

According to the gas law, the pressure of a gas generally directly proportional to its temperature at a fixed volume.

Gas law can be represented as:

[tex]P_{1} V_{1}/ T_{1} = P_{2} V_{2} / T_{2}[/tex]

Calculation of volume with the aid of gas law:

It is given that, [tex]P_{1}[/tex] = 45.8 kPa, [tex]P_{2}[/tex] = 99.3 kPa , [tex]T_{1}[/tex] = 57.2°C, [tex]T_{2}[/tex] = 112.3°C, [tex]V_{1}[/tex] = 115 mL .

Now, put the values of given data in gas laws equation.

(45.8kPa)(115mL)/(330K)= (99.3kPa)([tex]V_{2}[/tex])(385.3K)

[tex]V_{2}[/tex] = 61.9 mL

Therefore, the volume will be 61.9 mL .

Explicación:

Paso 1: Escribir la ecuación química balanceada

N₂ + 3 H₂ ⇒ 2 NH₃

Paso 2: Calcular el rendimiento teórico de NH₃ a partir de 140 g de N₂

En la ecuación balanceada, participan de N₂: 1 mol × 28.01 g/mol = 28.01 g y de NH₃: 2 mol × 17.03 g/mol = 34.06 g.

140 g N₂ × 34.06 g NH₃ /28.01 g N₂ = 170 g NH₃

Paso 3: Calcular el rendimiento porcentual de NH₃

El rendimiento experimental de NH₃ es 153 g. Podemos calcular el rendimiento porcentual usando la siguiente fórmula.

R% = rendimiento experimental / rendimiento teórico × 100%

R% = 153 g / 170 g × 100% = 90.0 %

Here heat is absorbed to break the crystalline nature of ice and to make well separation between water molecules.

Explanation:

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. ... Ice cubes melting as their temperature rises. During melting, the ice absorbs latent heat, which is used to change the state of the water from ice to liquid water.

Answer:

1.238 years will it take

Explanation:

The isotope decay of an atom follows the equation:

Ln[A] = -kt + ln[A]₀

Where [A] could be taken as the amount of the isotope after t years

[A] = 1.00mg

t = ?

k is the decay constant; k = ln2 / Half-life

k = ln 2 / 2.86 years = 0.2424 years⁻¹

[A]₀ is the initial amount of the isotope = 1.35mg

Replacing:

ln1 = -0.2424years⁻¹*t + ln 1.35

0.2424years⁻¹*t = ln 1.35

t =

Answer:

Robert Boyle

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Robert Boyle was the first to determine the relationship between the pressure and volume of a gas.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

[tex] PV = K[/tex]

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

Answer:

41.8 g of water.

Explanation:

To solve this, we introduce the concept of mol.

1 mol of anything contains 6.02×10²³ particles.

In this case, we talk about molecules of water.

Molecular weigh is 18 g/mol which indicates that 1 mol of water weighs 18 g.

So let's do the conversion

(18 g of water / 6.02×10²³ 1 mol of molecules) . 1.4×10²⁴ molecules = 41.8 g

In this case, since this is a problem about the combined gas law because the temperature, volume and pressure undergo a change:

[tex]\frac{P_2V_2}{T_2}= \frac{P_1V_1}{T_1}[/tex]

Answer:

Magnesium chloride.

Explanation:

When magnesium and chloride react with each other produces magnesium chloride. Magnesium belongs to second group in the periodic table which means it has two electrons in its outermost shell while on the other hand, chlorine belongs to seven group which means it has seven electrons in its outermost shell so it needs one electron to become stable. So in the reaction, magnesium loses two electrons and become cation whereas two chlorine atoms receives two electrons from magnesium and become anion. Ionic bond type is present between magnesium and chlorine atoms.
