Answer: Option D) covalent bonds between water molecules
In water, hydrogen bonds are best described as covalent bonds between water molecules
Explanation:
The hydrogen bonds between water molecules are covalent bonds because they are formed when oxygen attract the lone electron in hydrogen, thus resulting in the formation of a partially negative charge on the oxygen atom and a partially positive charge on two hydrogen atoms
Thus, the sharing of electrons between oxygen and hydrogen atoms is responsible for the covalent bonds between water molecules
The molecules will be more separated, and will have least amount of intermolecular force of attraction.
<h3><u>Explanation:</u></h3>
The molecules inside the jar of Lilly are moving around each other. This means the state of the matter present inside the jar is liquid. As Lily gives more energy inside the jar , the molecules inside the jar will get more separated as the kinetic energy of the molecules increase and the intermolecular force of attraction decreases as well as the intermolecular separation or distance increase. As the energy is continued to be supplied from outside, there will be a time when this liquid will reaches boiling point and will start to change into gas. After this point the intermolecular force of attraction will be least among molecules and their separation will be maximum.
Answer:
Coefficient: number balancing sulfuric acid in a chemical reaction.
Subscripts: number of atoms of each element forming the compound.
Explanation:
Hello!
In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:
- Two hydrogen atoms.
- One sulfur atom.
- Four oxygen atoms.
We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.
Moreover, since the molecules is given as 7 H2SO4
; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.
Best regards!
