Taken from a dictionary: "in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it."
Carbon has four valence electrons in its shell carbon can share electrons with up to four different atoms.
Answer: Yes it is large enough to store the acid.
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of acid = 225 grams
Density of acid =
Putting in the values we get:
Thus volume of the acid is and thus Erlenmeyer flask with volume of 150 ml is enough to contain the acid.
Answer is: from strongest to weakest attractions: ionic forces, covalent forces, hydrogen forces, Van der Waals forces.
Ionic bond is the electrostatic attraction between oppositely charged ions; ionic bond is very strong.
For example, sodium chloride (NaCl) has ionic bond between sodim cation and chlorine anion.
Covalent bond is bond between nonmetals. Hydrogen and oxygen are nonmetals.
For example, in water, atoms of hydrogen (H) and oxygen (O) are connected by polar covalent bonds.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
For example, because of hydrogen bonds, water has higher melting and boiling temperatures than H₂S.
There are two kinds of Van der Waals forces: weak London dispersion forces and stronger dipole-dipole forces.
