Answer:

The halogens

Explanation:

In the s and p-blocks, the halogens have the highest value of electronegativity.

This is because they only need one electron to complete their configuration.

Electronegativity is the tendency of an atom to draw electrons to itself in a covalent bond.
Halogens requires just one electron to complete their octet.
In a bond, they have more electronegativity than other elements.
The most electronegative atom is located in the halogen group.

<h2>Hello!</h2>

The answer is:

Hence, the new pressure will be 2.07 atm.

$P_{2}=2.07atm$

Since we know that the gas is inside of a rigid container, meaning that the volume will be kept constant, we can solve the problem using the Gay-Lussac's Law.

The the Gay-Lussac's Law establishes that when an ideal gas is kept at the same volume, the pressure and the temperature will be proportional.

We need to pay special attention when we are working with the Gay-Lussac's Law since its equaitons works with absolute temperatures (Kelvin ), so, if we are working with relative temperatures such as Celsius degrees or Fahrenheit degrees, we need to convert the temperatures to Kelvin.

We can convert from Celsius degrees to Kelvin using the following formula:

$Temperature(K)=Temperature(C\°)+273$

So, we have the Gay-Lussac's equation:

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

Also, we are given the following information:

$T_{1}=30\° \\P_{1}=2atm\\T_{2}=40\°$

Therefore, converting the temperature to Kelvin, we have:

$T_{1}=30C\°=30+273K=303K\\\\T_{1}=40C\°=40+273K=313K\\$

Now, calculating we have:

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

$P_{2}=\frac{P_{1}}{T_{1}}*T_{2}\\\\P_{2}=\frac{2atm}{303K}*313K=2.07atm$

Hence, the new pressure will be 2.07 atm.

$P_{2}=2.07atm$

Have a nice day!

A compound is formed when 171.2g of carbon reacts with 28.8 g of hydrogen what is the mass percent of hydrogen in the compound

PolarNik [594]

Hi.

You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.

28.8 ÷ (171.2 + 28.8) = 0.144

0.144 · 100 = 14.4

I believe the mass percent of the hydrogen in the compound is 14.4%
