Answer:

The answer to your question is: hydrogen bonding

Explanation:

Hydrogen bonding is a kind of interaction dipole-dipole, that means that 2 molecules attract each other because the have partial charges.

In the picture we can see 4 molecules of water, red circles are oxygens and white circles are hydrogens. In this bonding, Oxygen due to its size, and atomic number is more electronegative than hydrogen, then in water molecule is formed a partial negative charge in oxygen and a partial positive charge in hydrogen.

Finally, because of this partial charge, one oxygen can bond to one hydrogen of another molecule.

madam [21]

Answer:

highest first ionization energy - Br

smallest atomic size - Br

most metallic character - Na

Explanation:

Ionization energy of Br is higher than P because higher zeff value

Sodium is more metallic than calcium because it is able to loose electron more readily as compared to calcium because of higher electro positivity.

Atomic radius of Br is the smallest as its atomic radius is 114, P (115), Ca (197), Na (186)

If you have 1.00 mole of F2 at 1.00 atm of pressure and 0°C, what is the volume of F2?
ss7ja [257]

Answer:

V=22.4L

Explanation:

Hello,

In this case, by using the ideal gas equation, er can compute the volume of fluorine gas as shown below:

PV=nRT\\\\V=\frac{nRT}{P}=\frac{1mol*0.082\frac{atm*L}{mol*K}+(0+273)K}{1.00atm}  \\\\V=22.4L

Best regards.

Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa
Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.
