Which of the following statements is/are true regarding hydrogen bonds in water?

Choose all that apply.
A. Hydrogen bonds in liquid water organize water molecules into six-sided structures.
B. Hydrogen bonds are responsible for the high latent heat of melting of ice to liquid water.
C. Hydrogen bonds hold the atoms in a single water molecule together.
D. Hydrogen bonds are responsible for the high latent heat of vaporization of liquid water to water vapor.
E. Hydrogen bonds are responsible for the high heat capacity of water.

Answer

B,C,D,E

Explanation:

Hydrogen bonds in water forms a tetrahedral ( four sided structure) and not a six sided structure.

The hydrogen bonds are needed to be broken first when heat is applied to change from one state to another.It makes room for more heat to be applied than the required amount which signifies a higher latent heat of melting or vaporization and also a higher heat capacity .

your answer would be a. 12.5 kg

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
