"Select True or False: The following data for the reaction: A(g) + 2B(s) === AB2(g) provides evidence that the reaction is exoth

ermic.Table: Temp (K) K(c)300. 1.5 x 10^4600 55900. 3.4 x 10^-3.a) True b) False"This would be true because as we are increasing T, the K value is decreasing, which indicates that we are favoring the reactants; therefore, heat is a product, which means it is exothermic.

The reaction as shown is known to be an exothermic reaction.

<h2>Endothermic and exothermic reaction:</h2>

Depending on the temperature of the reaction vessel after reaction, the reaction could be classified as;

  • Endothermic
  • Exothermic

In an endothermic reaction, heat is absorbed and the rate of reaction increasing with increase in temperature while in an exothermic reaction, the rate of reaction decreases with increase in temperature.

Hence, the correct statements are;

  • The reaction is an exothermic reaction.
  • The value of K decreases as the value of T increases.

Which element has this electron configuration? <br> astatine<br> bromine<br> chlorine<br> fluorine
oksano4ka [1.4K]
Unfortunately you did not specify the electronic configuration in the question, however since one of the answers must be a halogen, i took the liberty to attach an image with the configuration (both the simple numeric and spdf form) for all the halogen and all you have to do is match the electronic configuration you have in your question to the one in the table attached and you can then deduce the answer.

Hope this helps.

Whats the difference between covalent and ionic bonds
il63 [147K]

Answer: The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms.Jan 23, 2020

Explanation: Hope this helped!!!!

explain how the number of valence electrons in atoms relate to their bonding with other atoms to form molecules ?????
Westkost [7]


valence electrons are the number of electrons in the outer shell. there can only be 8 electrons in the outer shell. The number of valence electrons can be used to determine how many bonds are needed.

For example: H2O

O (oxygen) has 6 valence electrons
H (hydrogen) has 1 valence electron

O needs 2 more electrons to be stable
H needs 1 more electron to be stable

O forms one bond with two H atoms to form H2O.
