Answer:
The empirical formula of the compound C₃H₆N₂ is C₃H₆N₂
Explanation:
The empirical formula of a compound is the formula of the compound given in the (smallest) whole number ratio of the elements of the compound
The empirical formula of S₂O₂ is SO
The empirical formula of C₃H₆O₃ is CH₂O
The given compound's molecular formula is C₃H₆N₂
The smallest whole number ratio of of the elements of the compound is 3:6:2, therefore, the empirical formula of the compound C₃H₆N₂ is C₃H₆N₂.
Answer:
D. ![2NaBr + Cl_2\rightarrow 2NaCl + Br_2](https://tex.z-dn.net/?f=2NaBr%20%2B%20Cl_2%5Crightarrow%202NaCl%20%2B%20Br_2)
Explanation:
Hello!
In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:
Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:
![2NaBr + Cl_2\rightarrow 2NaCl + Br_2](https://tex.z-dn.net/?f=2NaBr%20%2B%20Cl_2%5Crightarrow%202NaCl%20%2B%20Br_2)
![Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow Br_2^0+2e^-](https://tex.z-dn.net/?f=Cl_2%5E0%2B2e%5E-%5Crightarrow%202Cl%20%5E-%5C%5C%5C%5C2Br%5E-%20%5Crightarrow%20%20Br_2%5E0%2B2e%5E-)
Unlike the other reactions whereas no change in the oxidation states is evidenced.
Answer and Explanation:
Natural selection can benefit a species in many ways. One way natural selection benefits a species is by helping a species adapt to constant changing environments and biomes. natural selection can also benefit a species by dying of the weaker links of a species and adapting the mutated species
You should have given us a table, but I think my table shouldn't be too different.
Let's put oxidation numbers first.
![Mg^{0}(s)+Br_2^{0}(l) --> Mg^{+2}Br_2^{-2}(?)](https://tex.z-dn.net/?f=%20Mg%5E%7B0%7D%28s%29%2BBr_2%5E%7B0%7D%28l%29%20--%3E%20Mg%5E%7B%2B2%7DBr_2%5E%7B-2%7D%28%3F%29%20)
You would have to know that Mg(s) is a reducing agent and Br2(l) is an oxidizing agent. But it is pretty common knowledge that the halogens will tend to take the electrons and alkali and alkaline earth metals will tend to give up electrons.
Mg is oxidized because it gives up electrons; Br2(l) is reduced because it gains electrons. Since the reaction conforms to what we would expect to <em>naturally</em> (thermodynamically favored) occur, it can take place given that the activation energy is supplied.
