Answer:
Molecular oxygen and Hydrogen fluoride.
Explanation:
Definition:
Hydrogen bonding:
It is a type of dipole-dipole attraction between the hydrogen atom and more electronegative atoms.
In hydrogen bonding mostly the highly electronegative atoms are fluorine, nitrogen and oxygen.
Explanation:
In given compound such as methane CH₄ the electronegativity of carbon is 2.55 while that of hydrogen is 2.2 so there is smaller electronegativity difference that's why it can not form hydrogen bond.
In case of molecular oxygen the electronegativite atom oxygen is present. It can form hydrogen bonds with water. its electronegativity is 3.44.
In case of hydrogen fluoride the electronegativity atom fluorine is present. It will form hydrogen bonds with water. Its electronegativity is 3.98. So it is more likely to take part in hydrogen bonding.
Answer:
The volume of a sample of gas (2.49 g) was 752 mL at 1.98 atm and 62∘C 62 ∘ C .
Answer:
210
Explanation:
according to vectors since they are in two different direction u minus them
F1 =10 F2=220
F1 has a forward direction
while f2 goes backward
Copper wire is not an example of a pure element because although it's made by pure elements, it's not one itself. It's made by factories.
Have a nice day! :)
The cap-like acrosome covers the head of the sperm and releases enzymes that will help the sperm penetrate the egg.
<h3>What is acrosome?</h3>
The acrosome is a unique membrane organelle found over the anterior region of the sperm nucleus that has been largely preserved throughout evolution. This acidic vacuole includes a number of hydrolytic enzymes that, when produced, aid sperm penetration of the egg covers.
<h3>What is acrosome made of?</h3>
The acrosome is formed from the Golgi complex of the spermatid. The acrosome is made up of a protein matrix core and multiple hydrolytic and glycolytic enzymes that are essential for fertilization.
