Explanation:
NaCl is a strong salt of strong base and strong acid whereas HCl is a strong acid.
In the solution both dissociates in the solution into their respective ions as shown below:
NaCl ⇒ Na⁺ + Cl⁻
HCl ⇒ H⁺ + Cl⁻
Hence, the ions Na⁺, Cl⁻ and H⁺ are formed and there is no scope of reaction between them for a gas to evolve. They remain in the hydrated state in water.
Answer:
71.1
Explanation:
1 mol Fe = 10.4 g/55.85 g/mol = 0.186
1 mol AgNo3 = 28.4 g/169.87 g/mol = 0.178 mol AgNo3
then since Ag:Fe is 1:3, AgNo3 is the limiting reactant
So now
0.178 moles * 1/3 * 241.83 g/mol Fe(NO3)3 = 14.35 g Fe(NO3)3
Excess reactant: 0.178 moes AgNO3 * 1/3 = 0.059
0.186 - 0.059 = 0.127 moles Fe * 55.85 g/mol Fe = 7.1 g Fe excess
1 — Element D and A ( Which are Sodium and aluminium )
2 — ( 2 + 8 + 3 = 13 electrons total ) Element A Because it's atomic number is 13.
3 — Element E Is stable. ( Which is Argon )
( Note, Elements which has 8 election on its outermost cell is stable. ( Helium is exception which is a noble gas but have 2 electrons in outermost cell )
4 — Element F , which is hydrogen. ( Hydrogen is the only element to not have any neutron )
5 — Element D ( Which is sodium )
6 — The element F ( Which is hydrogen ) Don't contain any neutron.
