Answer: -

When electrons are fired at an element, the resulting interference pattern is called electron diffraction.

Electrons get scattered on hitting and they are observed via a luminescent screen. The pattern of scattered electrons is consistent with wave behavior like that of X rays.

The experimental evidence that electrons could act as waves was based on quantized wavelengths and diffraction pattern evidence is therefore correct.

Answer:

True

Explanation:

There was a theory proposed by the French physicist <u>Louis de Broglie</u> in 1923. This theory basically states that particles that are studied in quantum mechanics (for example, electrons and light), exhibit properties that can be seen when studying both particles, and waves. This theory was called Wave-Particle Duality.

When studying electrons, they were observed to behave like particles in certain experiments, however, in other experiments they also behaved how a wave would. We think of electrons as particles, which have mass, but they can also be diffracted like electromagnetic waves.

atroni [7]

Answer:

Ammonium chloride

Explanation:

The powder is:- Ammonium chloride

When mixed with silver nitrate, white prescipitate of silver chloride is formed as:-

NH_4Cl+AgNO_3\rightarrow NH_4NO_3+AgCl

When mixed with sodium hydroxide, ammonia gas is formed which has noxious order.

NH_4Cl +NaOH\rightarrow NH_3 + H_2O + NaCl

Ammonia gas on reaction with nickel (II) hydroxide forms deep blue colored complex as shown below:-

Ni(OH)_2(s) + 6NH_3(aq)\rightarrow [Ni(NH_3)_6]^{2+}(aq) + 2OH^{-}(aq)

solniwko [45]
Answer : Average atomic weight of copper atoms will be 63.62 u. 

Explanation : For calculating average atomic weight for any given atom we use this formula,

m = Σm_{i} X % abundance

where, m - avg atomic mass of isotope.
and m_{i} - mass of isotope

on solving we get, 
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.
