Answer:

He showed that by absorbing a discrete quantum of energy, an electron can jump from one orbit to another. ... In spite of his contributions to the Bohr model of the atom, Einstein remained deeply troubled by the notion that atoms seemed to emit photons at random when their electrons change orbits.

Which part of the mantle is still a solid but flows like a thick, heavy liquid?

marusya05 [52]

Hello!

Your answer is A, asthenosphere

The asthenosphere is a part of the mantle. It helps move the plates in the Earth.

It is below the lithosphere, between 80 and 200 km below the surface.

Therfore, the asthenosphere is the part of the mantle that is still a solid but flows like a thick, heavy liquid.

Hope this helps!

Have a great day!

What occurs when a solid substance dissolves into a liquid? 1 It stays solid and sinks to the bottom of the liquid substance. 2

katrin [286]

Explanation:

When a solid substance is dissolved in a liquid such as water, the intermolecular forces of attraction between the molecules in the solid substance are overcome and they exist as ions in the solution. Hence the answer is 2.

Predict the sign of ΔS° for 2NO2(g) LaTeX: \longrightarrow⟶ N2O4(g) CaCO3(s) + 2HCl(aq) LaTeX: \longrightarrow⟶ CaCl2(aq) + H2O(

prisoha [69]

Answer: a. $2NO_2(g)\rightarrow N_2O_4(g)$ : $\Delta S$ is negative

b. $CaCO_3(s)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l)$ : $\Delta S$ is negative

c. $Ag^+(aq)+Cl^-(aq)\rightarrow AgCl(s)$ : $\Delta S$ is negative

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa

a) $2NO_2(g)\rightarrow N_2O_4(g)$

In this reaction 2 moles of gaseous reactants are converting to 1 mole of gaseous products. The randomness will decrease and hence entropy will also decrease. Thus $\Delta S$ is negative.

b) $CaCO_3(s)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l)$

In this reaction solid reactants are converting to aqueous products. The randomness will increase and hence entropy will also increase. Thus $\Delta S$ is positive.

c) $Ag^+(aq)+Cl^-(aq)\rightarrow AgCl(s)$

In this reaction aqueous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus $\Delta S$ is negative
