Thermal
idk why but I just know
Answer:
The correct answers are:
<em>c. The concentrations of the products decrease</em>
<em>d. The equilibrium constant decreases</em>
Explanation:
Changes in temperature shift the equilibrium. In this problem, the reaction is endothermic, so it absorbs heat so heat is considered as a reactant:
Reactants + heat ⇒ Products
If the temperature is decreased, the heat is decreased, so reactants are removed from the reaction at equilibrium. According to Le Chaterlier's principle, the system will try to compensate the produced change. If reactants are removed, the systems will form reactants and the equilibrium will shift toward the left (formation of more reactants). In consequence, the amount of products will be decreased.
Thus, acorrect option is: c. The concentrations of the products decrease.
Since the equilibrium constant is given by the ratio of concentration of products over concentration of reactants, if the concentration of products decrease, the equilibrium constant also decreases. So, another correct option is: d. The equilibrium constant decreases.
Answer:
Cloud condensation nuclei or CCNs are small particles typically 0.2 µm, or 1/100 the size of a cloud droplet on which water vapor condenses. Water requires a non-gaseous surface to make the transition from a vapour to a liquid; this process is called condensation.
Answer:
Explanation:
Ca₃( PO₄)₂ = 3 Ca⁺² + 2 PO₄⁻³
x 3x 2 x
Let solubility be x mole per litre
solubility product = (3x )³ x ( 2x )²
= 108 x⁵ = 1.2 x 10⁻²⁹
x⁵ = .0111 x 10⁻²⁹ = .111 x 10⁻³⁰
x = .64 x 10⁻⁶ moles / litre
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.
<h3>What is the atmosphere?</h3>
An atmosphere is the layers of gases surrounding a planet or other celestial body.
The three important functions of the atmosphere are:
1. The atmosphere protects life on earth by preventing it from incoming ultraviolet (UV) radiation.
2. The atmosphere keeps the planet warm through the insulation effect.
3. The atmosphere maintains extremes between day and night temperatures.
