Answer:
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl.
Explanation:
Answer:
B
Explanation:
As you move from left to right, the number of protons increases. More protons means a bigger positive charge to pull in the electrons from the shells. This would then decrease the size of the atom.
Thus, the answer is B, the size decreases.

The critical point is said to be the end point of a phase diagram. The most known example is the liquid-vapor critical point, the point in a PT curve that signifies that at this point both vapor and liquid coexist. The critical point is characterized by a critical pressure and a critical temperature.
Answer : The products of the chemical reaction are, 
and 
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
When sodium bromide react with silver nitrate then it react to give sodium nitrate and silver bromide as a product.
The balanced chemical reaction will be:
The given reaction is a double-displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.
The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
In the balanced chemical reaction,
and 
are reactants.
and are products.
Hence, the products of the chemical reaction are, and
Answer:
Firing a muzzleloader leaves a corrosive residue inside the barrel that causes pitting and reduces accuracy. The buildup of residue, called fouling, also will make loading difficult. ... Black powder residue can damage the barrel if left overnight.
