Answer:

shift to restore equilibrium

Explanation:

Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.

Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.

Equilibrium is the state of a reversible reaction when:

• two opposing reactions occur at the same rate;

• the concentrations of reactants and products are constant

Which of these substances has the lowest pH? 0.5 M HBr, pOH = 13.5 0.05 M HCl, pOH = 12.7 0.005 M KOH, pOH = 2.3

vagabundo [1.1K]

<h3><u>Answer;</u></h3>

0.5 M HBr, pOH = 13.5 ; Has the lowest pH

<h3><u>Explanation;</u></h3>

From the question;

pH = -Log [OH]

or pH = 14 - pOH

Therefore;

For 0.5 M HBr

[H+] = 0.5 M

pH = - Log [0.5]

= 0.30

For; pOH = 13.5

pH = 14 - pOH

= 14 -13.5

= 0.5

For; 0.05 M HCl

pH = - log [H+]

[H+] = 0.05

pH = - Log [0.05]

= 1.30

For; pOH = 12.7

pH = 14 -pOH

= 14 -12.7

= 1.30

For; 0.005 M KOH,

pOH = - log [OH]

[OH-] = 0.005

pOH = - Log 0.005

= 2.30

pH = 14 - 2.30

= 11.7

For; pOH = 2.3

pH = 14 -pOH

= 14- 2.3

= 11.7

Answer:

Ti6Al4V1 or Ti6Al4V

Explanation:

So, from the question above we are given the following Important data or parameters or information which is going to help us in solving this question and they are;

The "surgical-grade" titanium is made up of 64.3% titanium, 24.19% aluminum and 11.42% vanadium.

This is a stoichiometry Question so in order to be able to solve this question one must have the basic knowledge of stoichiometry, it is advisable that one revise it.

So, let us delve right into the solution of this question. Recall that, the formula for Calculating the number of moles = mass/molar mass.

Hence, the number of moles of titanium,Ti = 64.3/47.87 = 3 moles.

Also, the number of moles of aluminum = 24.19/26.98 = 0.8966

For vanadium; 11.42/51 = 0.22

The next step is to divide each number of moles component by the lowest number of mole, that is;

Ti = 1.34/ 0.22 = 6; Al = 0.8966/0.22= 4 and V = 0.22/0.22 = 1.

Thus, the emperical formula is = Ti6Al4V.
