Answer:

<h2>844.4 mmHg</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{2 \times 760}{1.8}  =  \frac{1520}{1.8}  \\ =  844.4444...

We have the final answer as

<h3>844.4 mmHg</h3>

Hope this helps you

Which of the following are associated with the phenomenon of resonance in organic compounds? Select all that apply.
rusak2 [61]

Answer:

(B) Resonance will be a stabilizing factor.

(D) Charge is delocalized over several atoms.

Explanation:

Hello!

Resonance theory attempts to explain certain experimental data observed. Molecules such as benzene cannot be explained by previous theories because the experimental data does not match, for example, the link length is intermediate between a single and a double bond in said molecule.

Resonance theory explains the additional stability of certain molecules from the delocalization of electrons between several atoms.

. ¿Cuantos moles de Fosfato de Bario se producen cuando reaccionan 0.38 mol de Nitrato
kow [346]

Respuesta:

0.13 mol

Explicación:

Paso 1: Escribir la ecuación química balanceada

3 Ba(NO₃)₂ + 2 H₃PO₄ ⇒ Ba₃(PO₄)₂ + 3 H₂O

Paso 2: Establecer la relación molar apropiada

La relación molar de Ba(NO₃)₂ a Ba₃(PO₄)₂ es 3:1.

Paso 3: Calcular cuantos moles de fosfato de bario se producen a partir de 0.38 moles de nitrato de bario

0.38 mol Ba(NO₃)₂ × 1 mol Ba₃(PO₄)₂/3 mol Ba(NO₃)₂ = 0.13 mol Ba₃(PO₄)₂

Select the correct structure that
Leto [7]

Answer:

c) both

Explanation:

hey, could you check the question once because I suppose it's 2-hexyne when there's a triple bond and 2-hexene when there's a double bond between Carbon atoms. As of the question asked, it's c) both but it's 2-hexene due to presence of double bond between Carbon atoms.

do tell me as well. have a good day :-))
