Answer:
A reaction is at equilibrium when the amounts of reactants or products no longer change. Chemical equilibrium is a dynamic process, meaning the rate of formation of products by the forward reaction is equal to the rate at which the products re-form reactants by the reverse reaction.
Basaltic Rocks
Basaltic Rocks
The top layer of the sea floor is primarily composed of about 50 % basalt, which is the most common type of volcanic rock to be erupted.
Both igneous and sedimentary rock types can transform physically and chemically into a third rock type. Metamorphic rocks are formed when igneous or sedimentary ... Basalt
Granite is a common intrusive rock in continents. If magma with the same composition reaches the surface, it forms extrusive rocks such as rhyolite and pumice (PUHM-ihs). Basalt (buh-SAWLT) is an extrusive igneous rock that forms the ocean floor. Gabbro is an intru- sive rock that has the same composition as basalt.
Answer:
Heterogeneous mixture
Explanation:
Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture.
Answer:
b. protein
Explanation:
Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.
Triglycerides are made of a glycerol molecule esterified by three fatty acids.
Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.
The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.
