Answer:

Explanation:

Single displacement reactions  or single replacement reactions are reactions in which one substance is replacing another. The replacement of  a metallic ion in solution by a metal atom higher in the activity series than the metal in solution is one of such reaction. The positions of the elements on the activity series provides the driving force for the reaction to occur:

            A + BC → AC + B

A smaple of 1cm cuvette gives an absorbance reading of 0.558. if they absorptivity for this sample is 15000l/(mol.cm), what is t
Mazyrski [523]
To solve this problem, we use Beer's Law: A= ε.l.c
A is the absorbance- 0,558
<span>ε is</span> the molar absorptivity- is <span>15000 </span><span><span>L⋅mol-1</span><span>cm-1</span></span>
<span>l is </span>the length of the cuvette- 1 cm
<span>c is</span> the molar concentration

Applying the formula,
0,558= 15000 x 1 x c
0,558/15000= c
c= <span>3.72×<span>10⁻⁵ </span> <span>mol⋅L<span>⁻¹</span></span></span>

Lynne is riding her bike at a speed of 22.55<br> km/hr. What is this speed in mi/min?
antiseptic1488 [7]

Answer:

0.2335320064 mi/min

Explanation:

1 km/h = 0.0103561865 mi/min

1 mi/min = 96.56064 km/h

For conversion:

22.55 km/hr = 22.55 x 0.0103561865 mi/min = 0.2335320064 mi/min
