Answer: E. Occurs when methane gas is burned.
Explanation:
A chemical change occurs when matter undergoes a change to form a new substance with different chemical properties, and the reaction is usually not reversible.
In the case of burning methane gas (CH4) ,oxygen and methane are the reactants, while the new substance formed from the reaction are carbondioxide (CO2) and water (H2O) .
A cell is a microscopic living organism which is the smallest part of an organism such as a plant or animal.
Answer:
Option 3.
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Explanation:
To know which option is correct, we must have an ideal of what is acid–base neutralization.
Neutralization is a reaction involving an acid and a base which produces salt and water only.
With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.
From the question given above, only the 3rd equation gas water as part of the products i.e
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Hence, equation 3 is an acid-base neutralization reaction
B. He would be considered an Organic Chemist since Organic Chemistry is the study of Carbon and its compounds.
