Answer:
3.29 M
Explanation:
Molarity refers to the molar concentration of a solution and it can be calculated using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to this question, the mass of HCl was given to be 60.4 grams and the volume of water as 505 mL.
Using mole = mass/molar mass to convert mass of HCl to moles
Molar mass of HCl = 1.0079 + 35.453 = 36.4609g/mol
mole = 60.4g ÷ 36.4609g/mol
mole = 1.66mol
Volume of water = 505mL = 505/1000 = 0.505L
Molarity, M = 1.66 ÷ 0.505
Molarity of HCl solution = 3.29 M
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is 2(NH4)Cl + CuSO4.
Explanation:
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is
CuCl2 + (NH4)2SO4 ⇔ 2(NH4)Cl + CuSO4.
Here the left side one's are reactants i.e.,CuCl2 and (NH4)2SO4.
The right siders are products i.e.,(NH4)Cl and CuSO4.
The complete ionic equation is used to include both chemical species as well as spectator ions. It is used to indicate which of the reactants and products in the equation exists primarily as ions in aqueous solution.
It is nothing but a chemical equation in which electrolytes which are soluble in water are formed as dissociated ions.
The above chemical reaction is double displacement reaction.

Some indicators of rusting include:
a. color change
b. formation of as solid
Explanation:
Rusting is a redox ( a reaction in which reduction and oxidation occur concurrently) reaction which occcur when metallic iron is exposed to air and water or water vapor reacts with the oxygen and water to form a hydrated mixture of oxides of the metal.
The shiny metallic iron becomes oxidized to Fe²⁺ and Fe³⁺ ions while neutral oxygen gas molecules are reduced to O²⁻ ions. The shiny metallic iron also loses its lustrous appearance as the process proceeds and is covered by a layer of rust.
The equation for reaction is given below:
4Fe(s) + 30₂(g) + xH₂O(l) -----> 2Fe₂O₃. xH₂O(s)
The product of the reaction above is known as rust and is reddish-brown solid.
Rusting causes iron to become flaky and weak as rust is very light and porous, reducing the strength and appearance of iron which are desirable properties of iron when used in construction. The rusting of iron can lead to damage to automobiles, railings, bridges, and several other iron structures.
