Answer:
Crystal field splitting is the difference in energy between d orbitals of ligands. Crystal field splitting number is denoted by the capital Greek letter Δ. Crystal field splitting explains the difference in color between two similar metal-ligand complexes.
Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
Answer:
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series. Magnesium oxide decomposes into magnesium and oxygen. If 4.03 g of magnesium oxide decomposes to form 2.43 g of magnesium, what mass of oxygen gas is also released in the reaction
The word say magnesium oxide decomposes to magnesium and oxygen
the chemical symbols say
MgO-----------> Mg + O2 (since natural oxygen is diatomic)
the balanced equation says
2MgO-------------->2Mg + O2
4.03 gm----------> 2.43 + ?0 gms
tour high school Algebra I class says
? = 4.03 -2.43 =1.60
your chemical analytcal lab says %mO in MgO = 16/40.3 = 39.7%
your calculator says
39.7/100 X 4.03 = 1.60
all of these prove the law of conservation of mass
Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V = 
The cylindrical tube can hold 0.215 cubic decimeters of blood.
