Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is 
and one anion whose chemical symbol is 
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cation is formed by the metal sodium which forms and the anion is formed by non metal chlorine which forms .
For a formula unit of sodium chloride, the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus
and combine to form neutral 
Answer:
The answer is C. An electrochemical cell.
Explanation:
The aluminum ion react with the sulfide to form aluminum sulfide.
Answer:
Equal
Explanation:
When the bowling ball is first dropped, it has a maximum potential energy but minimum kinetic energy. The height is max, so the potential energy will be greatest. Velocity is 0, so kinetic energy will be 0.
Answer:
Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism's genes. ... Genetic engineering uses the techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly.
Explanation:
Data Given:
% w/w = 5 %
Solution weight = 1500 g
Solute weight = ?
Formula Used:
% w/w = (Mass of Solute / Mass of Solution) × 100
Solving for Mass of Solute,
Mass of Solute = (% w/w × Mass of Solution) ÷ 100
Mass of Solute = (5 × 1500 g) ÷ 100
Mass of Solute = 75 g K₂SO₄
