Answer:b

Explanation:

Answer:

6.52×10⁴ GHz

Explanation:

From the question given above, the following data were obtained:

Wavelength (λ) = 4.6 μm

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

Next we shall convert 4.6 μm to metre (m). This can be obtained as follow:

1 μm = 1×10¯⁶ m

Therefore,

4.6 μm = 4.6 μm × 1×10¯⁶ m / 1 μm

4.6 μm = 4.6×10¯⁶ m

Next, we shall determine frequency of the light. This can be obtained as follow:

Wavelength (λ) = 4.6×10¯⁶ m

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

v = λf

2.998×10⁸ = 4.6×10¯⁶ × f

Divide both side by 4.6×10¯⁶

f = 2.998×10⁸ / 4.6×10¯⁶

f = 6.52×10¹³ Hz

Finally, we shall convert 6.52×10¹³ Hz to gigahertz. This can be obtained as follow:

1 Hz = 1×10¯⁹ GHz

Therefore,

6.52×10¹³ Hz = 6.52×10¹³ Hz × 1×10¯⁹ GHz / 1Hz

6.52×10¹³ Hz = 6.52×10⁴ GHz

Thus, the frequency of the light is 6.52×10⁴ GHz

Answer:

1.00 mol

Explanation:

Step 1: Given data

Molecules of water: 6.02 × 10²³ molecules

Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water

In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

Answer:

Explanation:

Ionization energy of hydrogen atom is 13.6 eV . This energy will be provided by energetic proton , the kinetic energy of which is 1000 eV.  The kinetic energy of ionized electron is 15.2 eV . Kinetic energy of proton produced from from the ionization of hydrogen or the nucleus of the hydrogen atom is 4.3 eV . All these energy must have come from kinetic energy of initial proton.

So kinetic energy of projectile proton after collision

= 1000 - ( 13.6 + 15.2 + 4.3 ) eV.

= 966.9 eV .

Answer:

It can come from unstable atoms that undergo radioactive decay, or it can be produced by machines. Radiation travels from its source in the form of energy waves or energized particles. There are different forms of radiation and they have different properties and effects

Answer:  A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions

Explanation:

Answer:

increase

Explanation:

Reactions that are initiated by light are called photochemical reactions. The brighter the light, the faster the reaction.

Answer: An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Explanation: Literally learning about this in my science class XD

Answer:

See explanation

Explanation:

We know that

%ic of the interatomic bond = [1 - e^-(XA - XB)^2/4] * 100%

Now;

XA = electronegativity of Ti = 1.61

XB = electronegativity of Al = 1.54

Substituting values;

%ic of the interatomic bond = [1 - e^-(1.61 - 1.54)^2/4] * 100%

%ic of the interatomic bond = 0.12%

Given the low %ic of the interatomic bond, the bond is metallic.

The percent ionic character is 0% and the type of interatomic bonding would be metallic.

The percent ionic character can be determined by using the formula,

[tex]1-exp{-0.25(Xa-Xb)^{2} ][/tex]

• In the given equation, Xa and Xb refers to the electronegativities of the elements.  

• The intermetallic compound given is TiAl₃.  

• Based on the electronegativity table, the electronegativity of Al or Xa is 1.5 and the electronegativity of Ti or Xb is 1.5.  

Now putting the values in the above formula we get the % ionic character,

[tex]= 1-exp [-0.25 (Xa -Xb)^{2}]*100%\\\\\\=1-exp [-0.25 (1.5 -1.5)^{2}]*100%\\[/tex]

[tex]= 0 percent[/tex]

Thus, the ionic bond character is 0% and the compound TiAl₃ comprises two metals, it exhibits metallic bonding.

Answer:

12.2 g

Explanation:

Step 1: Write the balanced equation for the synthesis of SO₃ from S

S + 1.5 O₂ ⇒ SO₃

Step 2: Calculate the moles corresponding to 4.91 g of S

The molar mass of S is 32.07 g/mol.

4.91 g × 1 mol/32.07 g = 0.153 mol

Step 3: Calculate the theoretical yield, in moles, of SO₃ from 0.153 moles of S

The molar ratio of S to SO₃ is 1:1. The moles of SO₃ produced are 1/1 × 0.153 mol = 0.153 mol.

Step 4: Calculate the mass corresponding to 0.153 moles of SO₃

The molar mass of SO₃ is 80.06 g/mol.

0.153 mol × 80.06 g/mol = 12.2 g

Step 2: Calculate the final volume of the balloon

The balloon is filled with air. If we assume it behaves as an ideal gas, we can calculate the final volume of the balloon using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 0.5 L × 20 K/293 K = 0.03 L

Statement that gives description as regards energy and bonding changes between atoms such as fluorine become a molecule of fluorine, bond Energy is released as a bond is formed. Thus option 4 is correct.

The Bond Energy otherwise called as bond enthalpy  is a quantity that offers insight into the strength of a chemical bond.

The  ‘bond energy’ can also be represented as “the average value obtained from the bond dissociation enthalpies of all the chemical bonds  in a given chemical compound.

The bond energy of a chemical bond is directly proportional to the stability of that bond which implies that the greater the bond energy o between two atoms, the greater the stability of that chemical bond.

[tex]P_{Ar}=7.068mmHg[/tex]

Explanation:

Hello!

In this case, according to the given percent of argon in our atmosphere, it is possible to compute the pressure contributed by it as shown below:

[tex]P_{Ar}=P_{atm}*0.93\%[/tex]

Thus, we plug in to obtain:

[tex]P_{Ar}=760mmHg*0.0093\\\\P_{Ar}=7.068mmHg[/tex]

Best regards!

The pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]

Pressure is defined as the normal force acting on any surface in the case of gases it is the normal force acting on the surface of the earth.

now it is given in the question that the Argon contains 0.93%  part in the atmosphere.

So here are the calculations

[tex]\rm P_{Ar}=P_{Atm}\times 0.93[/tex]%

[tex]\rm P_{Ar}=700\times 0.93[/tex]%

[tex]\rm P_{Ar}=7.068\ mmHg[/tex]

Thus the pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]

Explanation:

Answer:70L

Explanation:

The volume occupied by 100g of oxygen gas at STP is 70L.

1 mole of a gas at STP occupies 22.4 L volume.

The same goes for oxygen gas, [tex]O_2[/tex]. 1 mole of [tex]O_2[/tex] occupies 22.4L volume.

Now the molar mass of [tex]O_2[/tex] is = 32g

So the number of moles of [tex]O_2[/tex] in 100g is

n = 100/32

n = 3.125 moles

Volume occupied by 3.125 moles or 100g of [tex]O_2[/tex] is

V = 3.125 × 22.4 L

V = 70 L volume is occupied by 100g of oxygen gas.
