weakness, There are two conditions that lead to a weak volcanic eruption, low viscosity magma and little presence of trapped gases.

strength, The VEI or (Volcanic Explosivity Index)  is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity. The numerical scale (from 0 to 8) is a logarithmic scale, and is generally analogous to the Richter and other magnitude scales for the size of earthquakes.

Answer:

-65 kJ

Explanation:

To use Hess's Law, you need to combine the equations in a way that results in the desired equation. To add reactants/products, just add the equations and their subsequent heat of reactions. Subtracting reactants/products involves flipping the signs of enthalpies, duplicating reactants/products involves multiplying the coefficients and enthalpies by a desired number.

    A + 2B -->   C + D

+            B --> 2C + D
------------------------------------

    A + 3B --> 3C + 3D

In this case, you only need to add the equations together to get the desired equation. Because you just add the equations, combine each equations' heat of reaction.

(-20 kJ) + (-45 kJ) = -65 kJ

The overall heat of reaction of the desired reaction is -65 kJ.

Answer: 44.0 g/mol

Explanation:

[tex]M=m.RT/PV[/tex]

M=1.211*0.082*296/ 0.987*0.677

M= 44 g/mol

A gas collected from a reaction has a mass of 1.211 g and occupies a volume of 0.677 L. The temperature in the laboratory is 296 K, and the air pressure is 0.987 atm  the molar mass of the gas 23.7 g/mol. option A is correct.

The universal gas law given by Boyle, Charles , Avogadro and Gauss known as combined gas law with respect to temperature, volume and pressure using universal gas constant and number of moles.

According to universal gas equation or combined gas equation

          P V = n R T

where , P = pressure

             V = volume

              n = number of moles

              R = universal gas constant = 8.313

               T = temperature

n = W / M.M

W = weight

M.M = molar mass

substituting the value in the equation

0.987 × 0.677 = 1.211 / M.M × 8.313 × 296

M.M = 23.7 g/mol

Therefore, gas collected from a reaction has a mass of 1.211 g and occupies a volume of 0.677 L. The temperature in the laboratory is 296 K, and the air pressure is 0.987 atm  the molar mass of the gas 23.7 g/mol. option A is correct.

Answer:

Dalton's law of partial pressure

Explanation:

In Dalton's law of partial pressure is states that the total pressure of a gas mixture is equal to the sum of the partial pressures of the component gasses.

This is the equation: [tex]P_{total} =P_{gas 1} +P_{gas2} + P_{gas3}[/tex].. so on and so forth.

basically what Dalton is saying partial pressures are just fractions of the total pressure, think of it as if you cut 12 slices of pizza and 12 people grabbed a slice of the pizza. Each person has 1/12 of that pizza, 1/12 x 12 = 1.  

let's say there is a container filled with nitrogen gas (N) , hydrogen gas (H), and ammonia gas (NH₃).

N= 40 atm

H=20 atm

NH₃= 10 atm

you would plug this information into this equation: [tex]P_{total} =P_{gas 1} +P_{gas2} + P_{gas3}[/tex]

[tex]P_{N} + P_{H} + P_{NH{3}} = P_{total}[/tex]

 [tex]P_{40} + P_{20} + P_{10} = 70[/tex]  

N is 40/70 of the gaseous mixture.

H is 20/70 of the gaseous mixture.

NH₃ is 10/70 of the gaseous mixture.

if you add these fractions up:

[tex]\frac{40}{70} +\frac{20}{70} +\frac{10}{70} =\frac{1}{1} =1[/tex]

Answer: 0.37 M

Explanation:

HCl has a gram-formula mass of 36.46 g/mol, so 40.0 g is about 40.0/36.46=1.10 mol.

A covalent bond is formed by the sharing of electrons between 2 atoms.

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Sharing of electrons forms covalent bonds between the atoms.

These bonds are mainly formed between two similar atoms of electronegativity.

Where ionic bonds are formed by sharing electrons where there is an electronegativity difference between metals and non-metals. Ex. NaCl

Hence, a covalent bond is formed by the sharing of electrons between 2 atoms.

Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.

Given that quantity of salt solution = 2.50 L

We know that, 1 L = 1.06 qt

Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:

2.50L = 2.50L × 1.06qt/L = 2.65qt

Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.

Following are the harmful effects caused by the oxides of nitrogen

Nitrogen oxides causes irritation in mucous membrane.

Large concentrations of Nitrogen oxide causes lungs problems in humans

It causes injuries to vegetation by damaging leaves.

Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.

Answer: the gas molecules interact with one another

Explanation:

According to the forces of attraction, the  gas molecules interacting  with one another makes a gas non - ideal.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

P₁V₁/T₁ = P₂V₂/T₂

Given the data in the question;

We substitute our given values into the expression above.

P₁V₁/T₁ = P₂V₂/T₂

( 0.980atm × 14.5L )/293.15K = ( 0.973684atm × 14.3L )/T₂

14.21Latm / 293.15K = 13.92368Latm / T₂

14.21Latm × T₂ = 13.92368Latm × 293.15K

14.21Latm × T₂ = 4081.72679LatmK

T₂ = 4081.72679LatmK / 14.21Latm

T₂ = 287.24K

T₂ = 14.09°C

Explanation:

#4: Morality is Moles/ Liters

So take 3.2 mols ÷ 3.6 L = 0.8888... since there are 2 sig figs in the question the answer would round to 0.89 mol/L

#5: to find the number of moles needed, you take the mol/L and multiply that by the volume.

0.89 mol/L ×0.400L = 0.356 mols. the liters cancel out. Since 0.89 has the least number of sig figs your final answer should have 2. which it 0.36 mols.
