What is the angle between two of the nitrogen-hydrogen bonds in the ammonium (NH4+) ion?

Chemistry

Arlecino [84]3 years ago

Answer:

109° 27'

Explanation:

The ammonium ion is tetrahedral in shape, all the HNH bonds are exactly at the tetrahedral bond angle since there are only bond pairs in the structure and no lone pairs. Recall that lone pairs decrease the bond angke from the ideal value in a tetrahedron due to higher repulsion.

What is the kinetic energy of a 1-kilogram ball is thrown into the air with ab ititial velocity of 30m/s?
mariarad [96]
KE=1/2*mass*velocity^2
So u do 1/2 * 1 * 30^2
1/2 * 1 * 900
= 450kgm/s

P.s. I'm not sure if I would have to convert kg to g.
Anyways hope this helped

Calculate the energy of a photon of 765 nm wavelength light in J.
weqwewe [10]

Answer:

2.6×10^-19 J/photon

Explanation:

E  of photon  =  h  ×  ν

where h= 6.63 × 10^-34 j.s

v= C ÷ λ

E = ( h × c) ÷ λ

E = (6.63 × 10^-34 × 3.00 ×10^8 )  ÷ ( 765 × 10^-9)

E = 2.6×10^-19 J/photon
