Answer: B. silver sulfide
Explanation:
The law of conservation of mass states that atoms cannot be created nor destroyed in a chemical reaction, so an element that is NOT on the reactants side (the left side) CANNOT be on the products side (the right side), because that element cannot be created in a chemical reaction.
Our reactants are silver and sulfur, so only silver and sulfur will be in the products, so that eliminates lead bromide and glucose, because they do not have silver nor sulfur in them. Sulfuric acid has sulfur in it, but it also has oxygen and hydrogen, but no silver, so that choice is eliminated as well. That leaves silver sulfide, which is Ag₂S.
I hope this helps! :)
In the given reaction equation, silver + sulfur, the missing compound that is formed is silver sulfide.
Silver (Ag) is a metal, and sulfur (S) is a non-metal. When these two elements react, they combine to form a compound called silver sulfide (Ag2S).
It's important to note that the subscript 2 in Ag2S indicates that there are two silver atoms bonded to one sulfur atom. This balanced formula accurately represents the compound formed in the reaction.
Therefore, the missing compound from the equation is B. silver sulfide.
b. evaporation
c. filtration
d.sorting
SORTING METHOD can easily be used to separate a mixture of steel ball bearing and marbles. This separation method is suitable because the two substances that are mixed together have big sizes, so it is easy to separate the two by hand picking the particles. Sorting method is usually used as a separation technique when the size of the mixture is big and the mixed substances are in the same state.

Answer:
Valence electrons are the electrons located in an atom's outermost shell. They play a critical role in chemical bonding and reactions and determine the atom's reactivity and placement in the Periodic Table.
The electrons located in the outermost shell of an atom are correctly referred to as valence electrons. These electrons play a crucial role in chemical bonding and reactions because they are the most distant from the atom's nucleus and thus, the most loosely bound, making them available for interactions with other atoms. For instance, when atoms interact to form a chemical bond, the valence electrons are often the ones that are shared, transferred, or involved in the bond formation. The number of valence electrons in an atom also determines the atom's reactivity and its placement in the Periodic Table.
