Answer:

2.06 × 10⁻¹⁰

Explanation:

Let's consider the solution of a generic compound AB₂.

AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)

We can relate the molar solubility (S) with the solubility product constant (Kps) using an ICE chart.

      AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)

I                      0              0

C                    +S            +2S

E                      S              2S

The solubility product constant is:

Kps = [A²⁺] × [B⁻]² = S × (2S)² = 4 × S³ = 4 × (3.72 × 10⁻⁴)³ = 2.06 × 10⁻¹⁰

750.0g of water that was just boiled (heated to 100.0/c loses 78.45KJ of heat as it cools.What is the final temperature of water
Iteru [2.4K]
  • Mass=m=750g=0.75kg
  • Q=78.45\times 10^3J=78450J
  • T_i=100°C
  • T_f=?
  • Specific heat capacity=c=4200J/kg°C

According to thermodynamics

\\ \tt\bull\rightarrowtail Q=mc\Delta T

\\ \tt\bull\rightarrowtail Q/mc=\Delta T

\\ \tt\bull\rightarrowtail \Delta T=\dfrac{78450}{0.75(4200)}

\\ \tt\bull\rightarrowtail \Delta T=24.9°C

\\ \tt\bull\rightarrowtail T_i-T_f=24.9

\\ \tt\bull\rightarrowtail T_f=100-24.9=76.1°C

Answer:

The Sun and the planets were born from a cloud of gas and dust called the solar nebula 4.6 billion years ago. The collapse of the solar nebula was most likely triggered by a shock wave from a nearby supernova explosion. The Sun formed in the center, with the planets surrounding it in a thin disk.

What happens when a chemical change occurs
Alona [7]
Chemical change happens when a substance combines with another substance to form a new substance. It produces chemical reactions and generally is not reversible except by further chemical reactions. Heat is sometimes produced in some reactions. When chemical reactions occur, the atoms are rearranged and an energy change happens along with it as new products are generations. At a molecular level, chemical changes involves the making or breaking of bonds between atoms. Some examples of chemical change are iron rusting (iron oxide forms) and bread rising (yeast converts carbohydrates into carbon dioxide gas).
