How much heat is absorbed during production of 147 g of NO by the combination of nitrogen and oxygen?

marin [14]

Answer:

$\large \boxed{\text{105 kcal}}$

Explanation:

MM: 30.01

N₂ + O₂ ⟶ 2NO; ΔH = +43 kcal/mol

m/g: 147

Treat the heat as if it were a reactant in the reaction. Then you can write

N₂ + O₂ + 43 kcal ⟶ 2NO

The conversion factor is then 43 kcal/2 mol NO.

1. Moles of NO

$\text{Moles of NO} = \text{147 g NO} \times \dfrac{\text{1 mol NO}}{\text{30.01 g NO}} = \text{4.898 mol NO}$

2. Amount of heat

$\text{Heat} = \text{4.898 mol NO } \times \dfrac{\text{43 kcal}}{\text{2 mol NO}} = \text{105 kcal}\\\\\text{The reaction absorbs $\large \boxed{\textbf{105 kcal}}$}$

If 26.2 mL of AgNO3 is needed to precipitate all the Cl− ions in a 0.785-mg sample of KCl (forming AgCl), what is the molarity o

sweet-ann [11.9K]

Answer:

The molarity of the $AgNO_3$ solution is $4.02 \times 10^4 M$

Explanation:

The Balanced chemical equation is

$1AgNO_3 (aq) +1KCl (aq) > 1 AgCl (s)+1KNO_3 (aq)$

Mole ratio of $AgNO_3$ : KCl is 1 : 1

So moles $AgNO_3$ = moles KCl

$Moles KCl = \frac {mass}{molarmass}$

$= \frac {0.785 mg}{(39.1+35.5 g per mol)}$

$= \frac {0.000785 g}{74.6 g per mol}$

$= 0. 0000105 mol KCl$

$= 0.0000105 mol AgNO_3$

So Molarity

$= \frac {moles of solute}{(volume of solution in L)}$

$= \frac {0.0000105 mol}{26.2 mL}$

$=\frac {0.0000105 mol}{0.0262 L}$

= 0.000402M or mol/L is the Answer

(Or) $4.02 \times 10^4 M$ is the Answer

Products and reactants are used and created at the same rate when a reaction is at this stage

V125BC [204]

This means that the reaction is in dynamic equilibrium.

Hope this helps because I don't really know the question you asked :)))

When water evaporates

vladimir1956 [14]

c) The motion of water molecules causes them to leave the liquid and become a gas

Explanation:

When water evaporates, the motion of water molecules causes them to leave the liquid and become a gas. Evaporation is merely a phase change in which liquids changes to solid.

During the process of evaporation, heat energy causes the motion of the particles or molecules to increase.
This will then break the intermolecular forces holding them together leading to more freedom of the molecules.
The molecules will then move from being liquids to solids.
