Given:1 inch = 2.54 cm (exact)1 pound = 454 g1 Liter = 1.0b quarts1 foot = 12 inches1 galion = 4 quarts1 pound = 16 ouncesCalcul
svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)

Which one of the following pairs of acids and conjugate bases is incorrectly labeled or incorrectly matched? Acid Conjugate Base
vekshin1

Answer : The incorrect option is, (d) NH_4^+/NH_2^-

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

(a) The equilibrium reaction will be,

HF+H_2O\rightleftharpoons F^-+H_3O^+

In this reaction, HF is an acid that donate a proton or hydrogen to H_2O base and it forms F^- and H_3O^+ are conjugate base and acid respectively.

In this reaction, HF/F^- are act as a conjugate acid-base.

(b) The equilibrium reaction will be,

HClO+H_2O\rightleftharpoons ClO^-+H_3O^+

In this reaction, HClO is an acid that donate a proton or hydrogen to H_2O base and it forms ClO^- and H_3O^+ are conjugate base and acid respectively.

In this reaction, HClO/ClO^- are act as a conjugate acid-base.

(c) The equilibrium reaction will be,

H_2O+H_2O\rightleftharpoons OH^-+H_3O^+

In this reaction, H_2O is an acid that donate a proton or hydrogen to

In this reaction, H_2O/OH^- are act as a conjugate acid-base.

(d) The equilibrium reaction will be,

NH_4^++H_2O\rightleftharpoons NH_3+H_3O^+

In this reaction, NH_4^+ is an acid that donate a proton or hydrogen to H_2O base and it forms NH_3 and H_3O^+ are conjugate base and acid respectively.

In this reaction, NH_4^+/NH_3 are act as a conjugate acid-base.

(e) The equilibrium reaction will be,

H_3O^++H_2O\rightleftharpoons H_2O+H_3O^+

In this reaction, H_3O^+ is an acid that donate a proton or hydrogen to H_2O base and it forms

In this reaction, H_3O^+/H_2O are act as a conjugate acid-base.

From this we conclude that that, NH_4^+/NH_2^- pairs of acids and conjugate bases is incorrectly labeled or incorrectly matched.

Hence, the incorrect option is, (d) NH_4^+/NH_2^-

Answer:

The answer to your question is: density = 0.5 g/ml

Explanation:

Data

Volume = 10 ml

mass = 5 g

Density = ?

Formula

density = mass / volume

Substitution

density = 5/ 10

density = 0.5 g/ml
