Which of the following compounds can be considered a Lewis acid and not a Bronsted-Lowry acid? A acetylene hydronium ion © iron

8_murik_8 [283]

Answer:

iron (III) bromide

Explanation:

Bronsted-Lowry acid -

The species which can release proton , when dissolved in water .

Lewis acid -

The electron deficient species are called the Lewis acid .

From the question ,

The iron (III) bromide is a Lewis acid but not a Bronsted- Lowry acid because it can accept electrons pairs but cannot release proton .

The other options are -

The hydronium ion, the hydrochloric acid and the acetylene are Bronsted- Lowry acids because they can release proton .

And since , all the Bronsted- Lowry acids are Lewis acids .

How much would the temperature of 275 g of water increase if 36.5 kj of heat were added?

Andrew [12]

Answer: The temperature increase will be 31.70°C.

Explanation:

To calculate the increase in the temperature of the system, we use the equation:

$q=mc\Delta T$

where,

q = Heat absorbed = 36.5 kJ = 36500J

m = Mass of water = 275 g

c = Specific heat capacity of water = $4.186J/g^oC$

$\Delta T$ = change in temperature = ? °C

Putting values in above equation, we get:

$36500J=275\times 4.186J/g^oC\times \Delta T\\\\\Delta T=31.70^oC$

Hence, the temperature increase will be 31.70°C.

In order to study hydrogen halide decomposition, a researcher fills an evacuated 1.11 L flask with 0.822 mol of HI gas and allow

Elza [17]

Answer:

Kc = 168.0749

Explanation:

2HI(g) ↔ H2(g) + I2(g)

initial mol: 0.822 0 0

equil. mol: 2(0.822 - x) x x

∴ [ HI ]eq = 0.055 mol/L = 2(0.822 - x) / (1.11 L )

⇒ 1.644 - 2x = 0.055 * 1.11

⇒ 1.644 = 2x + 0.06105

⇒ 2x = 1.583

⇒ x = 0.7915 mol equilibrium

⇒ [ H2 ] eq = 0.7915mol / 1.11L = 0.7130 M = [ I2 ] eq

⇒ Kc = ([ H2 ] * [ I2 ]) / [ HI ]²

⇒ Kc = ( 0.7130² ) / ( 0.055² )

⇒ Kc = 168.0749

Ira Lisetskai [31]

Answer:

In each Amplify Science unit, students figure out

a phenomenon by asking questions, gathering

evidence, and coming up with an explanation of how

the phenomenon works. The Coherence Flowchart

visually represents the storyline of the unit, showing

the coherent flow of questions, evidence, and ideas that

support students as they build complex explanations

of the unit’s anchor phenomenon. The Coherence

Flowchart on the following pages (one chapter per

page) can be used to see the connections between

the questions that drive students’ experiences, the

evidence they gather, the ideas they figure out, and the

new questions that those ideas generate. The diagram

to the right explains the structure of a chapter in the
