Answer:
NH3 , SO3 , BF3
Explanation:
trigonal planar = AB3 ------------> Coordination number = 3
for example = NH3 , SO3 , BF3
all of them are trigonal planar
Answer:
Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution. A concentrated solution of sodium oxide in water will have pH 14. ... For example, it reacts with dilute hydrochloric acid to produce sodium chloride solution.
Answer:
Use E = h*c / lambda, where h is Planck's constant, c is the speed of light, and lambda is the wavelength.
E = (6.626 * 10^-34 J*s x 3.00 * 10^8 m/s) / (1*10^-6 m) = 1.99 * 10^-19 J
Explanation:
Explanation:
Ph=14-4.23
Ph=9.77
Its a Base because bases have high Ph and acids have low ph
Answer:
2 electrons
Explanation:
The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons.
