A. false. Colder water sinks because its denser. It's particles are closer together due to the temperature.
B. True. Liquids of higher density sink.
C. False. Seawater is denser than freshwater due to the salt particles in it
D. False. The higher the salinity, the higher the density. High salinity means there's more salt mixed into a specified volume. The more particles in a specified volume, the higher the density.
Your answer is B
A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.
The options are missing in the question statement. However, I managed to find from another source. These are
A.they ruled much of West Africa
B.they built large cities in the West African rain forest
C. they controlled the gold for salt exchange
D. they grew powerful through trade
Answer:
B. They built large cities in the West African rain forest.
Explanation:
"They built large cities in the West African rain forest" doesn't describe all three kingdoms of Ghana, Mali, and Songhai. Ghana, Mali, and Songhai were three of the greatest western African trading states. They controlled the trade of gold, salt, and merchandise between North Africa and sub-Saharan Africa in the 16th century. Their strong trade grew them powerful.
