I hope that this helps! Best of luck!
Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.
Answer:
a. angiotensin II
Explanation:
Angiotensins are a set of peptide hormones that cause vasoconstriction and a subsequent increase in blood pressure, its main objective is to lower blood pressure.
Aldosterone is a hormone produced by the adrenal cortex that inhibits the level of sodium excreted in the urine, maintaining volume and blood pressure.
Nitric acid is a viscous and corrosive liquid that can cause severe burns in living things. It is used as a laboratory reagent and to make explosives such as nitroglycerin and trinitrotoluene, as well as fertilizers such as ammonium nitrate.
The atrial natriuretic peptide is a polypeptide and is related to the homeostatic control of body water, sodium, potassium and adipose tissue.
