Why are sulphur and oxygen in group 6 in terms of electronic configuration

Irina-Kira [14]

Answer: Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. ... O=O. double bonds are much stronger than S=S double bonds.

A sample of sulfur dioxide (SO2) is initially at a temperature of 105C, a volume of 15 L, and a pressure of 1.5 atm. If the volu

Agata [3.3K]

The new pressure is 1.08 atm

From the question, we are to determine the new pressure

Using the General gas equation,

$\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}$

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature

P₂ is the final pressure

V₂ is the final volume

and T₂ is the final temperature

From the given information,

P₁ = 1.5 atm

V₁ = 15 L

T₁ = 105 C = 105 + 273.15 = 378.15 K

V₂ = 25 L

T₂ = 181 C = 181 + 273.15 = 454.15 K

P₂ = ?

Putting the parameters into the equation, we get

$\frac{1.5 \times 15}{378.15} = \frac{P_{2} \times 25 }{454.15}$

$P_{2}= \frac{1.5 \times 15 \times 454.15}{25 \times 378.15}$

P₂ = 1.08 atm

Hence, the new pressure is 1.08 atm

You complete a chemical reaction and recover 79 grams of product. However, you calculate you should have recovered 104 grams of

spin [16.1K]

Percent yield is calculated using:
$percent \: yield = \frac{actual \: yield}{theoretical \: yield} \times 100\%$

Your actual yield is how much you actually had at the end of the experiment = 79g.

Your theoretical yield is how much you calculated you should have gotten in an ideal, perfect experiment = 104g.

So put those values into the equation:
$percent \: yield = \frac{79}{104} \times 100\% = 76\%$

What function is most affected if the sepal of a flower is damaged by air pollution?

stepladder [879]

Answer:answer in explanation try to understand dear

Explanation:Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy.
