Answer:

32, 30 and 41

Explanation:

The problem here is to find the number of:

Protons, neutrons and electrons in Ge²⁺

In this ion,

We must understand that for a net positive charge to remain on an atom, the number of protons must be greater than the number of electrons.

Ge is Germanium with atomic number of 32;

So the number of protons is 32

Since the atom has lost two electrons;

Number of electrons now is 32 - 2 = 30

Number of neutrons is 41 from the periodic table.

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

Angelina_Jolie [31]

Answer:

sodium sulfite) Na2SO3 + HCl (hydrochloric acid). This reaction is a gas evolution reaction. The products are sodium chloride (NaCl), sulfur dioxide (SO2) and water (H2O). Sulfurous Acid (H2SO3) is produced as an intermediate in this reaction.

D. is the missing element.

Carlos <em>hasn’t done research</em> on what other scientists have observed and investigated on this topic. If he hasn’t done his literature research, he may just be repeating the experiments of other scientists working in the same area.

Options “A.”, “B.”, and “C.” are all part of the scientific method.
