6 0

Answer:

b. Ar-CHCHX2

Explanation:

The hydrogen atoms when combine with carbon atoms forms the carbon hydrogen molecule. There is 1H NMR which means two hydrogen atoms are adjacent to the carbon atoms. The correct choice is b and there is one hydrogen and one carbon atoms adjacent to each other forming a molecule.

The chemical reaction between the reactants:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Explanation:

We have the following chemical reaction:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Complete ionic equation:

3 Ag⁺ (aq) + 3 NO₃⁻ (aq) + Fe³⁺ (aq) + 3 Cl⁻ (aq) → 3 AgCl (s) +   Fe³⁺ (aq) + 3 NO₃⁻  (aq)

We remove the spectator ions and we get the net ionic equation:

Ag⁺ (aq) + Cl⁻ (aq) → AgCl (s)

where:

(aq) - aqueous

(s) - solid

What is the mass of 2.70 ×10^22 molecules of NaOH (Molar mass = 40.0 g/mol)?
Viefleur [7K]
Data:
Molar Mass of NaOH = 40 g/mol

Solving: <span>According to the Law Avogradro, we have in 1 mole of a substance, 6.02x10²³ atoms/mol or molecules
</span>
1 mol -------------------- 6.02*10²³ molecules
y mol -------------------- 2.70*10²² molecules

6.02*10²³y = 0.270*10²³ 
y =  \frac{0.270*\diagup\!\!\!\!\!\!10^{\diagup\!\!\!\!\!\!23}}{6.02*\diagup\!\!\!\!\!\!10^{\diagup\!\!\!\!\!\!23}}
\boxed{y \approx 0.04\:mol}


Solving: <span>Find the mass value now
</span>
40 g ----------------- 1 mol of NaOH
x g ------------- 0.04 mol of NaOH

x = 40*0.04
\boxed{\boxed{x = 1.6\:g}}\end{array}}\qquad\quad\checkmark

Answer:
The mass is 1.6 grams
