Answer:

T₂ = 687.6 K

Explanation:

Given data:

Initial pressure = 108 Kpa = 108/101 = 1.06588 atm

Initial temperature = 20°C = 20+273.15 = 293.15 k

Final temperature = ?

Final pressure = 2.50 atm

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.06588 atm / 293.15 K = 2.5 atm/T₂

T₂ = 2.5 atm ×293.15 K / 1.06588 atm

T₂ = 732.875 atm. K /1.06588 atm

T₂ = 687.6 K

Aluminum reacts with oxygen to form aluminum oxide. Select the correct unbalanced skeleton equation for this reaction. A. Al(s)

Natasha2012 [34]

Answer:

D. Al(s) + O₂(g) → Al₂O₃(s)

Explanation:

Aluminum is a solid metal, so it is written as Al(s).

Oxygen is a diatomic gas, so we write this compound as O₂(g).

Aluminum oxide has the formula Al₂O₃ because in oxides the oxidation number of oxygen atom is -2 and for aluminum, the oxidation number is 3. Thus, we write this compound as Al₂O₃(s).

Now, we have to found the chemical equation in which the reactants (left side) are Al(s) and O₂(g) while the product (right side) is Al₂O₃(s). From the options, we can see that the correct is (D):

Al(s) + O₂(g) → Al₂O₃(s)

<h3>Further explanation</h3>

Given

the structure of the alkanes

Required

match the image to the name

Solution

Alkanes are saturated hydrocarbons with all of the carbon bonds being single bonds

General formula:

$\large {\boxed {\bold {C_nH_2n + 2}}}$

If we look at the picture, we define the black atom as Carbon and the branch is Hydrogen

To determine the name of the alkane, all we have to do is count the number of Carbon atoms

Butane : C₄H₁₀ : 4 C atoms

Methane : CH₄ : 1 C atom

Ethane : C₂H₆ : 2 C atoms

Propane : C₃H₈ : 3 C atoms

A wave at sea travel with a velocity of 25 m/s. If it has a wavelength of 10 m, what is it’s frequency?

stealth61 [152]

Answer:

2.5 Hz

Explanation:

Formula for the given question is:

Velocity= frequency X Wavelength.

v= f X λ.

25 = 10 X f

f= 2.5 Hz
