Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by firstly setting up the equilibrium expression for the given reaction, in agreement to the law of mass action:
![K=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Next, we plug in the given concentrations on the data table to obtain:
Regards!
Answer:
Covalent
Step-by-step explanation:
Covalent substances have relatively weak intermolecular forces. Many covalent substances such as hydrogen and oxygen are gases at room temperature, so they have low melting points.
<em>Ionic substances</em> have strong ion-ion attractive forces, and <em>metals </em>have strong metallic (electron-metal cation) attractions. I don't know of any metals or ionic compounds that are gases at normal conditions.
Answer: e. All voltaic (galvanic) cells involve the use of electricity to initiate nonspontaneous chemical reactions.
Explanation:
Electrochemical cell or galvanic cell or voltaic cell is a cell which converts chemical energy to electrical energy.
There are two electrodes in an electrochemical cell , where one is called as anode and one is called as cathode.
At cathode reduction takes place and at anode oxidation takes place.Thus the electrons generated at anode travel towards cathode and flow of electrons lead to generation of electricity.
Thus chemical reactions lead to generation of electricity.
Thus the statement that all voltaic cells involve the use of electricity to initiate nonspontaneous chemical reactions is false.
