Water is a polar molecule, meaning the covalent bonds in it share electrons unequally. They spend more time around the oxygen, making it positive and the hydrogens negative. This helps water stick to surfaces, a property called adhesion. The hydrogens of one molecule are also attracted to the oxygens of another. This is called cohesion, and it helps water form droplets
Carbon can form four covalent bonds.
Hydrogen can form one covalent bond.
Nitrogen can form three covalent bonds.
Oxygen can form two covalent bonds.
Answer:
Explanation:
Hello there!
In this case, we can identify the solution to this problem via the Dalton's rule because the partial pressure of helium is given by:
Whereas the mole fraction of helium is calculated by firstly obtaining the moles and then the mole fraction:
Then, we calculate the partial pressure as shown below:
