Describe the difference between a strong acid and a weak acid?

A strong acid dissociates completely when you put it in water. So for example, if you put a certain amount of HCl in water, all of it will dissociate into H+ and Cl-A weak acid doesn't undergo full dissociation. So if you put a certain amount of something like CH3COOH (acetic acid) in water, only some of the acetic acid will dissociate into H+ and CH3COO-

Question 5 (1 point)

Aleksandr-060686 [28]

Answer : The pressure it exert under these new conditions will be, 87 atm

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 19 atm

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas = 100 L

$V_2$ = final volume of gas = 20 L

$T_1$ = initial temperature of gas = $25^oC=273+25=298K$

$T_2$ = final temperature of gas = $0^oC=273+0=273K$

Now put all the given values in the above equation, we get:

$\frac{19atm\times 100L}{298K}=\frac{P_2\times 20L}{273K}$

$P_2=87atm$

Therefore, the pressure it exert under these new conditions will be, 87 atm

How are forces measured and modeled?

Elodia [21]

Answer:

In physics, force is a push or pull on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape. The unit of measure for force is the newton which is abbreviated as "N". One newton is the force needed to accelerate one gram of mass by one centimeter per second squared.

Plssss help meeeeeeee

Montano1993 [528]

All you need to do is to look at both sides of the equation and see who has the same element, state, coefficient, and charge and those will be your spectator ions.

In this question, the spectator ions would be $Na^{+}$ and $Cl^{-}$ .
