Answer:
2M
Explanation:
Given parameters:
Number of moles of FeCl₃ = 0.3 moles
Volume of water = 150mL
Unknown:
Molarity of solution = ?
Solution:
The molarity of a solution is the number of moles of solutes in a given solution. It is one of the ways of expressing concentration. The unit is always M i.e mol/dm³.
Molarity =
Express the volume in dm³;
150mL gives 0.15dm³
Molarity =
= 2M
Answer:
H+/PO-4^-2
Explanation:
hydrogen has dissolved completely
Answer:
The genetic element is the insulator.
Explanation:
The insulator is a basic component of the eukaryotic genomes. In recent studies, insulators have been found in many eukaryotic cells ranging from yeast to human. These genetic elements can clog the enhancer–promoter communication and can also prevent the movement of repressive chromatin. They also can be used to restrict the actions of silencers and enhancers in the system. Insulators can also efficiently protect the gene expression from the negative and positive chromatin effects. Another important function of the insulator is to serve as a regulatory element and prevent genes from unnecessary regulatory interactions.
Answer:
In the quantum-mechanical model of an atom, electrons in the same atom that have the same principal quantum number (n) or principal energy level are said to occupy an electron shell of the atom. Orbitals define regions in space where you are likely to find electrons.
Salt is soluble in water.
