chemical properties and same number of shell
Explanation:
elements in the same group have the same number of eletrons in their outermost shell and hence have the same chemical properties
Answer:
In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That is, the gas drives oxygen away from the fire, thus stopping the chemical reaction.
Answer:
0.85M
Explanation:
Given parameters:
Mass of CuCl₂ = 400g
Volume of water = 3.5L
Unknown:
Molarity of the solution = ?
Solution:
Molarity is one of the ways of expressing the concentrations of a solution. It is defined as the number of moles per unit volume of a solvent.
Molarity = 
To find the number of moles of CuCl₂;
Number of moles = 
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.6g/mol
Number of moles = 
= 2.97moles
Molarity = 
= 0.85M
Answer:
Yes they woll react.
Explanation:
Ferous oxide and zinc will be product.
Answer:
it is D
Explanation:
NaOH and chlorine gas
Electrolysis of Aqueous NaCl Since water can be both oxidized and reduced, it competes with the dissolved Na+ and Cl– ions. Rather than producing sodium, hydrogen is produced. ... The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.
