Answer:

The waves travel in a direction parallel to direction of the vibration of the medium

The waves travel in a direction parallel to direction of the vibration of the medium

A mechanical wave is defined as an oscillation of matter which is responsible for energy transfer via  medium.

The propagation of  wave is limited by the medium of transmission, the oscillating material which revolve around a fixed point with little translational motion.

A surface wave which is an example of  mechanical wave that propagate  along the interface of two different media in physics. other common examples are Gravity waves on the surface of liquids, ocean waves.

Surface wave can be propagated in a slow way through Earth material and are generally lower in frequency than body waves.

Answer:

4.935×10-1

Explanation:

Take away the 0

Given

Reaction

C+02 = CO2

Required

The equilibrium constant

Solution

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction  

pA + qB -----> mC + nD  

[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]

So for the reaction :

C+O₂ ⇔ CO₂

[tex]\tt Kc=\dfrac{[CO_2]}{[C][O_2]}[/tex]

Answer:

CsNO₃

Explanation:

The reactants are:

         Cesium chloride  = CsCl

          Silver nitrate  = AgNO₃

Products:

           Silver chloride  = AgCl

The other product:

 Now;

        CsCl  +    AgNO₃  →  AgCl  + ?

The other product is CsNO₃

So;

      CsCl  +    AgNO₃  →  AgCl  +    CsNO₃

Answer:

The manner in which objects will move is determined by the answer to this question. Unbalanced forces will cause objects to change their state of motion

Explanation:

Since these two forces are of equal magnitude and in opposite directions, they balance each other.

Answer:

balance force are those force whose resultant force is zero and unbalanced force are those whose resultant are non zero

Answer:

54.66 liters

Explanation:

First of all, remember this. 1 mole equals 22.4 liters.

Second of all, to show your work use dimensional analysis.

Write 2.44 moles and then put moles on the bottom and liters on top.

2.44 moles of O * 22.4 liters / 1 mol of O

Moles will cancel out.

2.44 x 22.4 = 54.656

Usually I would have used sig figs. But the question said to round your answer to two digits after the decimal point.

54.656 rounds to the hundreths place.

So 54.656 = 54.66

All in all, the final answer is 54.66 liters(don't forget the units).

Explanation:

Answer:

The temperature at which rhenium becomes superconducting is -271.6 ºC.

Explanation:

We can convert the temperature given in Kelvin, which is an absolute scale, into degrees Celsius. which is a relative scale, by a simple algebraic translation, that is:

[tex]T_{C} = T_{K} - 273[/tex] (1)

Where:

[tex]T_{C}[/tex] - Temperature, measured in degrees Celsius.

[tex]T_{K}[/tex] - Temperature, measured in Kelvins.

If we know that [tex]T_{K} = 1.4\,K[/tex], then the temperature given in degrees Celsius is:

[tex]T_{C} = 1.4\,K-273[/tex]

[tex]T_{C} = -271.6\,^{\circ}C[/tex]

The temperature at which rhenium becomes superconducting is -271.6 ºC.

Answer:

1.593 moles

Explanation:

Therefore, 1.593 moles are equal to 89.23 g of calcium oxide.

Answer:

9.64 × 10²³ molecules

Explanation:

Given data:

Mass of calcium oxide = 89.23 g

Number of molecules = ?

Solution:

First of all we will calculate the number of moles of calcium oxide.

Number of moles = mass/molar mass

Number of moles = 89.23 g/ 56.1 g/mol

Number of moles = 1.6 mol

Number of molecules;

1 mole contain 6.022 × 10²³ molecules

1.6 mol × 6.022 × 10²³ molecules / 1mol

9.64 × 10²³ molecules

The number 6.022 × 10²³ is called Avogadro number.

Answer:

3) Compound 1 is ionic, and compound 2 is molecular

Explanation:

Compound-1 is an ionic compound while Compound-2 is a molecular compound. Option 3 is correct.

Ionic Compound:

They are formed when an atom donates its electron to another atom. This results in one positive and one negative ion.

Hence, it is a very strong bond. These compounds have a very high melting and boiling point. They are very good electric conductors in the aqueous solution.

For example- NaCl.

Molecular compounds:

They are compounds that are made up of discrete molecular units. For example- [tex]\bold {H_2O}[/tex]

They have very weak intermolecular bonds hence have low boiling and melting point and do not conduct electricity.

SInce Compound-1 has higher MP and BP and Compound-2 has low melting and boiling point.

Therefore, Compound-1 is an ionic compound while Compound-2 is a molecular compound.

Kp/Kc = RT

Given

Reaction

A(g) ⇌ C(g)+B(g)

Required

Kp/Kc

Solution

For reaction :

pA + qB ⇒ mC + nD  

[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]

While the equilibrium constant Kp is based on the partial pressure  

[tex]\large {\boxed {\bold {Kp ~ = ~ \frac {[pC] ^ m [pD] ^ n} {[pA] ^ p [pB] ^ q}}}}[/tex]

The value of Kp and Kc can be linked to the formula '  

[tex]\large {\boxed {\bold {Kp ~ = ~ Kc. (R.T) ^ {\Delta n}}}}[/tex]

R = gas constant = 0.0821 L.atm / mol.K  

Δn=moles products - moles reactants or

number of product coefficients-number of reactant coefficients  

For reaction :

A(g) ⇌ C(g)+B(g)

number of product coefficients = 1+1=2

number of reactant coefficients   = 1

Δn= 2 - 1 =1

So Kp/Kc = RT

Answer:

436.55841 grams.

Explanation:

The molecular formula for Iron(III) Iodide is FeI3. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Iron(III) Iodide, or 436.55841 grams.

You use the 1 / 436.55841 conversion rate. This is different for each element, according to the stoichiometry tables. Iron(II) oxide would be 2/3 of the 1/436.55841 conversion rate, that is, multiplying the fraction to denominator.
