My fee structure is based on an hourly time charge basis. Architectural services (for renovation and new construction): 20% of construction costs. Interior design services: 35% commission on all goods and services.I work a lot of different ways.ypical fee structure is 15-20% of construction costs plus reimbursable expenses. My billing practices are based on a 35% commission over cost to my clients. Then I charge a basic design fee to initiate my contracts of usually $100,000. This fee varies, however, on the size and scale of the project.
A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit. The prefix poly-means many, in Greek, but even ions of two atoms are commonly referred to as polyatomic.ts chemical formula is O H â . An ammonium ion is made up of one nitrogen atom and four hydrogen atoms: it has a charge of +1, and its chemical formula is N H 4 + . Polyatomic ions are often useful in the context of acid-base chemistry or in the formation of salts.
Look at Table 9.3 on page 257. Circle the letter of a polyatomic ion that is a cation. a. ammonium b. acetate c. oxalate d. phosphate 13. How many atoms make up the oxalate ion and what is its charge? 14. What three hydrogen-containing polyatomic anions are essential components of living systems? a. _____ b. _____ c. _____ A polyatomic ion is a tightly bound group of atoms that behaves as a unit and carries a charge. Element Name Formula Fluorine Calcium Oxygen fluoride ion calcium ion oxide ion Fâ Ca2+ O2â false The sulfite ion has one less oxygen atom than the sulfate ion. It is made up of 6 atoms (2 carbon atoms and 4 oxygen atoms) and it has a charge of 2 .
