Answer:

Los huesos se mantienen unidos a otros huesos a través de unas largas tiras fibrosas llamadas ligamentos. El cartílago, una sustancia flexible y elástica que contienen las articulaciones, sujeta los huesos y los protege en los puntos donde varios huesos friccionan entre sí.

Given a chemical equation, showing the dissociation of an acid in solution, be able to identify the "acid", the "base", the "con

Karo-lina-s [1.5K]

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory:

An acid is defined as a substance which looses donates protons and thus forming conjugate base
A base is defined as a substance which accepts protons and thus forming conjugate acid.

$HA+H_2O\rightarrow A^-+H_3O^+$

Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.

HA = Acid

$H_2O$ = Base

$A^-$ = Conjugate base

$H_3O^+$ = Conjugate acid

For example:

$H_2SO_4+2H_2O\rightarrow SO_4^{2-}+2H_3O^+$

Sulfuric acid dissociating in its solution to form conjugate base and conjugate acid.

Sulfuric acid = Acid

$H_2O$ = Base

$SO_^{2-}$ = Conjugate base

$H_3O^+$ = Conjugate acid

Determine the ph of a 0.00598 m hclo4 solution. 1.777 6.434 7.566 2.223 3.558

Black_prince [1.1K]

Answer: 2.223
Explanation:
HClO4, also known as perchloric acid, is a very strong. This means we can assume that complete dissociation occurs.
This means that:
[H+] = [HClO4] = <span>0.00598

pH = -log[H+]
pH = -log[</span><span>0.00598] = 2.223

Note: The base of the log is 10 (conventionally we don't write the base if it is 10)</span>

What does the phrase i meter per second mean

slega [8]

The phrase 1 meter per second is a unit of velocity and is a unit of rate. 1 meter per second means for every second, for example, a man runs, he travels 1 meter distance. 1 meter per second is a derivative of the primary units of SI system, meter for distance and second for time.
