Answer:
The answer is lithium(LI)
Answer:
Synthesis
Explanation:
Reaction Given:
NH₃+ HCI ------> NH₄Cl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
NH₃+ HCI ------> NH₄Cl
In this reaction two reactant combine and give 1 products.
Reactant of the reaction
NH₃ = Ammonia
HCl = Hydrochloric acid
Product of the reaction
NH₄Cl = Ammonium chloride
So,
That ammonia (NH₃) react with Hydrochloric acid (HCl) and produces salt.
in this reaction NH₃ is a week base and take a proton from HCl and form ammonium ion and Cl ion. these two ions in combine form gives a salt called ammonium chloride.
Type of Reaction:
This is type of synthesis reaction, in which NH₃ and HCl combine and form a new compound that is ammonium chloride salt (NH₄Cl). As the synthesis reaction is that reaction in which two are more compounds or molecules combine and form a new compound.
Answer:
B) mutagens
Explanation:
Mutagens are substances that causes mutation. Mutation involves alteration of the genetic materials of an organism.
Substances such as ultra-violet radiation, x-rays, nitrous acid, viruses, fungal-infections e.t.c leads to the physical, chemical and biological alteration of genetic sequences to produce a mutant. A mutant is an organism whose genetic sequence has been altered.
Note: Pathogens are disease causing organisms. Vectors are carriers of pathogens.
Answer:
Neon
Explanation:
1s² 2s² 2p⁶ 3s¹ or [Ne] 3s¹
The outer most shell is the 3s¹.
For this atom to achieve stability, if it loses the electron in the 3s shell, it would resemble an inert element with a complete octet configuration. Therefore, the atom would be like:
1s² 2s² 2p⁶ which is the configuration of Ne
