Explanation:

A 1.00-L flask was filled with 2.00 moles of gaseous SO₂ and 2.00 moles of gaseous NO₂ and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous NO was present. Assume that the reaction

SO₂ + NO₂ ⇌ SO₃ + NO

occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.

Step 1: Calculate the molar concentrations

Since the reaction takes place in a 1.00 L flask, the molar concentrations are:

[SO₂]i = 2.00 M

[NO₂]i = 2.00 M

[NO]eq = 1.21 M

Step 2: Make an ICE chart

        SO₂ + NO₂ ⇌ SO₃ + NO

I       2.00   2.00       0        0

C        -x       -x         +x       +x

E    2.00-x  2.00-x    x         x

Step 3: Calculate the concentrations at equilibrium

The concentration of NO at equilibrium is 1.21 M. Then, x = 1.21.

[SO₂]eq = 2.00-1.21 = 0.79 M

[NO₂]eq = 2.00-1.21 = 0.79 M

[SO₃]eq = x = 1.21 M

[NO]eq = x = 1.21 M

Step 4: Calculate the value of the equilibrium constant, K, for this reaction

K = [SO₃] × [NO]/[SO₂] × [NO₂]

K = 1.21²/0.79² = 2.35

Answer:

Tsunamis are usually triggered by earthquakes, volcanic eruptions and underwater explosions, landslides and other mass movements. Underseas earthquakes have generated nearly all the major tsunamis in history. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.

Explanation:

Answer A is correct because of the fact that tsunamis can be caused by underwater explosions

The best description that shows the relationship between earthquake and tsunami is an underwater earthquake can cause a tsunami.

The correct option is (A).

Tsunamis are waves that form when the ocean surface moves suddenly due to earthquakes.

Some other causes of tsunami are landslides on the sea floor land collapsing into the water, massive volcanic eruptions, or a meteorite strike in the ocean.

The displacement or collision of tectonic plates of earth lithosphere causes earthquake.

The earthquake in the sea or ocean surface leads to tsunami.

Thus, option (A) An underwater earthquake can cause a tsunami is the correct option.

The micromoles of mercury(II) iodide : 0.013 μ moles

Given

215.0mL of a 6.0x10⁻⁵mmol/L HgI₂

Required

micromoles of HgI₂

Solution

Molarity(M) = moles of solute per liters of solution

Can be formulated :

M = n : V

n = moles

V = volume of solution

V = 215 mL = 0.215 L

so moles of solution :

n = M x V

n = 6.10 mmol/L x 0.215 L

n = 1.312 . 10⁻⁵ mmol

mmol = 10³ micromol

so 1.312 mmol = 1.312.10⁻⁵ x 10³ = 0.01312 micromoles ⇒ 2 sif fig = 0.013 μ moles

Answer:

mass of silver chloride (AgCl) = 3.0135  grams

Explanation:

The chemical equation is:

[tex]AgNO_{3(aq)} + NaCl_{(aq)} \to AgCl_{(s)} + NaNo_3_{aq)}[/tex]

No. of mole  = molarity × volume

For AgNO3:

No. of moles = 1.00 × 0.055

= 0.055 moles

No. of moles of NaCl = 0.84 × 0.025

= 0.021 moles

From the equation:

[tex]1 \ mol e \ of \ AgNO_3 \ react \ with \ 1 \ mole \ o f \ NaCl[/tex]

Therefore, 0.055 moles of AgNO3 react with 0.055 moles of NaCl

Here;

NaCl serves as the limiting reactant

Thus,

1 mole of NaCl will react with AgNO3 to yield 1 mole of AgCl

∴

0.021 moles of NaCl react with AgNO3 to yield 0.021 moles og AgCl

mass of AgCl = no of moles × molar mass

= 0.021 × 143.5

= 3.0135  grams

Answer:

rare username has joined the meeting.

Explanation:

Answer:

2450 mg

Explanation:

From the given information:

The total weight of the capsule = 12.5 mg + 37.5 mg

= 50 mg

The percentage of drug in each capsule = [tex]\dfrac{12.5}{50} \times 100[/tex]

= 25%

= 0.25

To make 0.5 mg of drug in each  100 mg of powder after dilution;

Then, the drug percent in each capsule after dilution is:

[tex]=\dfrac{0.5}{100}\times 100[/tex]

= 0.5%

= 0.005

Suppose (p) mg represent the amount that is added to the diluent in the given capsule. Then;

The total amount is = (50 + p) mg

Since the amount of the drug = 12.5 mg

Then the concentration  [tex]=\dfrac{12.5}{50 + x}[/tex] which needs to be equal to the needed concentration that is diluted.

i.e.

[tex]\dfrac{12.5}{50 + x} = 0.005[/tex]

By cross multiply;

(50 + x) 0.005 = 12.5

(50 × 0.005) + (0.005x) = 12.5

0.25 + 0.005x = 12.5

0.005x = 12.5 - 0.25

0.005x = 12.25

x = 12.25 / 0.005

x = 2450 mg

Thus, there is a need for an additional 2450 mg to make a dilution that compass 0.5 mg of drug in 100 mg powder.

Answer: 5.4

Explanation: The Law of Impenetrability says that two objects can't occupy the same space at the same time; therefore, the pennies and the water can't occupy the same space at the same time. Without the pennies the water level read 20.6 mL, dropping in the pennies gives a level of 26.0.

A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Volume in mL of the stack of 15 pennies is  26.0 mL.

A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that may be used to indicate volume, the most common ones are litres, m³, gallons, milliliters, teaspoon, as well as ounces.

Due to the Law of Impenetrability, which states that two items cannot occupy the same place at the same time, neither can pennies nor water. When the pennies are added, the water level rises to 26.0 mL from 20.6 mL before.

Mass is the quantity of matter a material contains, whereas volume is indeed the space that it occupies. The density of a sample is the quantity of mass in a given volume.

Therefore, volume in mL of the stack of 15 pennies is  26.0 mL.

Answer:

[NH₃] = 14.7 mol/L

Explanation:

28 wt% is a type of concentration that indicates that 28 g of ammonia is contained in 100 g of solution.

Let's determine the amount of ammonia:

28 g . 1 mol / 17.03g = 1.64 moles of NH₃

You need to consider that, when you have density's data it is always referred to solution:

Mass of solution is 100 g, let's find out the volume

0.90 g/mL = 100 g /V

V = 100 g / 0.90mL/g → 111.1 mL

We convert the volume to L → 111.1 mL . 1 L/1000mL = 0.1111 L

mol/L = 1.64 mol/0.1111L → 14.7 M

mol/L = M → molarity a sort of concentration that indicates the moles of solute in 1L of solution

Answer:

The number of electron in neutral atom of nitrogen are 7.

Atomic mass = 14 amu

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

The number of electron in neutral atom of nitrogen are 7.

Thus its atomic number is also 7.

Atomic mass = number of proton + number of neutron

Atomic mass = 7 + 7

Atomic mass = 14 amu
