Which of the following is the strongest base? Cl- Br- NH2 – HO- HS – H2O The Correct Answer and Explanation is: Correct Answer: NH₂⁻ Explanation To determine which of the given species is the strongest base, we need to examine their basicity—that is, their ability to accept a proton (H⁺). A strong base has

Which is the stronger base in water, NH2- or -OH? a) NH2-, because the negative charge is delocalized making the nitrogen more willing to accept a proton. b) NH2-, because the nitrogen is less electronegative and cant hold the negative charge as well as oxygen c) -OH, because the negative charge is delocalize making the
Your cousin Throckmorton skateboards from rest down a curved ramp in the form of a quarter circle of radius. Assume that the wheels of the skateboard roll without slipping and that the friction in the wheel bearings is negligible. If we treat Throcky and his skateboard as a particle of mass, he undergoes (nonuniform) circular
Your cousin Throckmorton skateboards from rest down a curved, frictionless ramp. If we treat Throcky and his skateboard as a particle, he moves through a quarter-circle with radius R = 3.00 m. Throcky and his skateboard have a total mass of 25.0 kg. (a) Find his speed at the bottom of the ramp. (b) Find
