Detergent has a ph of about 10. is detergent acidic or basic? use figure 8-3 to answer this question.
harina [27]

Answer is: detergent is basic.

pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity an aqueous solution.  

When pH is less than seven (pH<7), solution is acidic.  

When is equal seven (pH = 7), solution is neutral.  

When pH is greater than seven (pH > 7), like in this example, solution is basic.

(23.4m)(14m) rounded off to the correct number of significant figures
VARVARA [1.3K]

The value of the given expression up to correct significant figures is 330 m^2.

  • The rule that applies for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

  • The rule that applies for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

Given:

The expression: (23.4m)(14m)

To find:

The answer up to correct a number of significant figures.

Solution

Number of significant figures in '23.4' = 3

Number of significant figures in '14' = 22

=(23.4m)(14m)\\=(23.4m)\times (14m)\\=327.6 m^2

The number with the least significant figures is '14' is 2, so the answer will be reported up to 2 significant figures:

=327.6 m^2\approx 330 m^2

Number of significant figures in '330' = 3

The value of the given expression up to correct significant figures is 330 m^2.

Determine the value of the equilibrium constant (report your answer to three significant figures) for the following reaction if
Debora [2.8K]

Answer:

6.25e-6 is the value of the equilibrium constant

Explanation:

we have this equation

PbBr(s) ----- Pb^{2+}(aq)  + 2Br(aq)

When at a state of equilibrium,

we have the concentration of Pb^2+ to be 0.01

we have the concentration of Br^- to be 0.025

the equilibrium constant concentration of both pure solids and liquid s are said to be equal to 1

[PbBR2] = 1

such tht

Keq = [Pb^2+] x [Br-]^2

we already know the values of these from the above.

0.01x0.025^2

= 0.01 x 0.000625

= 0.00000625

= 6.25 x 10^-6

= 6.25e^-6
