What makes an ionic difference than a covalent bond

1 answer:

3 0

I’m not completely sure what you mean here but if your talking about charges in covalently bonded molecules then here is something:

Charges in covalent bonds are partial because the ions are shared when bonding.

The charges are no longer full and strong they are half charges, they are not as strong.

You might want to just google a little bit. :)

Hope that helps

Convert 2.0 micrometer to centimeters and to inches

Dima020 [189]

Answer:

2x10⁻⁴cm and 7.9x10⁻⁵ inches

Explanation:

Micrometer, μm, is an unit of length. Could be related with another units of lenght as, for example:

1.0μm = 1x10⁻⁴cm

1.0μm = 3.93701x10⁻⁵ inches

That means, 2.0μm are:

2.0μm * (1x10⁻⁴cm / 1μm) = 2x10⁻⁴cm

And:

2.0μm * (3.93701x10⁻⁵ inches / 1μm) = 7.9x10⁻⁵ inches

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

How do greenhouse gases in the atmosphere affect Earth’s temperature?

Maurinko [17]

Answer: The greenhouse gases cause Earth's surface to heat up from the sunlight.

Explanation: The greenhouse gases causes the Earth's surface to warm up in the morning and at night, the surface cools down. When it cools down, that gives the heat a chance to get back into the air, but some of the heat is trapped (which is caused by the greenhouse gases). That's why, on average, Earth stays at 58 degrees Fahrenheit.
