The compound that has the element ratio 2:1 is 2H20. 
In 2H2O, four atoms of hydrogen react with two hydrogen of oxygen to form molecules of water. Four divided by two will give two, that implies ratio 2;1. This implies that, two atoms of hydrogen will react with one atom of oxygen to give a molecule of water.<span />

what is the pressure, in atmospheres, of 2.97 mol h2 gas if it has a volume of 73 liters when the temperature is 298 k? 0.50 atm
Triss [41]
P x V = n x R x T

P x 73 = 2.97 x 0.082 x 298

P x 73 = 72.57492

P = 72.57492 / 73

P = 1.0 atm

hope this helps!

What kind of intermolecular forces act between a hydrogen cyanide molecule and a potassium cation?
andriy [413]

Answer:

ion-dipole

Explanation:

Let us remember that the potassium cation is an ion, a positive ion to be precise.

There is a dipole existing in the hydrogen cyanide molecule. The positive end of the dipole is on hydrogen while the negative end of the dipole is on the cyanide moiety.

The only possible interaction between the potassium cation and the hydrogen cyanide is an ion dipole interaction. The cation interacts with the cyanide moiety having a partial negative charge in the molecule.
