Answer:
A.) Q < K because Q decreased
B. shift right
Explanation:
Reactant-------->Products
K = Product/Reactant
An endothermic reffers to any reaction which absorbs energy from its surroundings, usually in the form of heat.
ΔH. In endothermic reactions, K increases when Temperature increases.
The given reaction is an endothermic reaction, and in an endothermic reaction, when there is increase in temperature, the product side is more favored. The system will shifts to the right side of the reaction. Q < K then K is constant and Q is decreased.then Q < K because Q decreased
The system respond to a temperature increase by shifting to the right
Answer:
The element iodine forms an anion with the charge -1. The symbol for this ion is I⁻¹, and the name is iodide. The number of electrons in this ion is 7.
Explanation:
Hello,
In this case, we have to consider iodine has the capacity to accept the electrons lost by other elements such as metals or hydrogen by becoming negatively charged. Such phenomena makes iodine to form an anion (negatively charged) with the charge -1, since it only needs one electron to attain the octet. Moreover, the symbol of such ion is I⁻¹ and its name is iodide. By cause of the aforementioned, the number of electrons it has is 7 since at its outer shell seven electrons are found (see electron configuration Kr,5s²,5p⁵).
Best regards.
Answer:
Concentrated sulfuric acid can perform a dehydration reaction with table sugar. After mixing, the color changes from white to brownish and eventually to black. The expansion of the mixture is the result of vaporization of water and CO2 inside the container.
Answer:
your answer would be : examples such as Thallium-206, Lead-210, & Bismuth-214.
It is easier to predict the boiling point of heptene rather than its melting point because of their geometrical isomerism.
<h3>What is melting point?</h3>
Melting point is that point at which any compound changes its state from solid to another state liquid, and at this point both the states are present in equilibrium.
It is easier to predict the boiling point of heptene as in this molecule constant number of double bond is present its not changing. But due to double bond heptance shows cis and trans isomer, and among them one isomer will be stable and another one is unstable.
That's why it is not easy to predict the melting point.
Hence, due to geometrical isomers it is not easy to predict melting point.
