What is the wavelength of a microwave with a frequency of 2450 mhz
JulsSmile [24]

Answer:

See below

Explanation:

The way to calculate this

  speed of light =  wavelength * frequency

   3 x 10 ^8 m/s   =   wavelength * 2450000000 Hz

       wavelength = .12245 meters

                    = 1.2245 x 10^-1  Meters

You have 846 ml of 3.95 M HCl. Using a volumetric pipet, you take 268 ml of that solution and dilute it to 803 ml in a volumetri
Anettt [7]

Answer: The concentration of hydrochloric acid in the final solution is 0.72 M

Explanation:

According to the dilution law,

M_1V_1=M_2V_2

where,

M_1 = molarity of stock solution = 3.95 M

V_1 = volume of stock solution = 268 ml

M_2 = molarity of diluted solution = ?

V_2 = volume of diluted solution = 803 ml

3.95\times 268=M_2\times 803

M_2=1.32M

Next, you take 100.00 ml of that solution and dilute it to 184 ml in a volumetric flask.

According to the dilution law,

M_1V_1=M_2V_2

where,

M_1 = molarity of stock solution = 1.32 M

V_1 = volume of stock solution = 100 ml

M_2 = molarity of diluted solution = ?

V_2 = volume of diluted solution = 184 ml

1.32\times 100=M_2\times 184

M_2=0.72M

Thus concentration of hydrochloric acid in the final solution is 0.72 M

Coordination chemistry of the carboxylate type siderophore rhizoferrin: the iron(iii) complex and its metal analogs
Afina-wow [57]

solution;

Rhizoferrin is a member of a new class of siderophores (microbial iron transport compounds) based on carboxylate and hydroxy donor groups rather than the commonly encountered hydroxamates and catecholates. We have studied the coordination chemistry of rhizoferrin (Rf), as a representative of this group, with Fe(3+), Rh(3+), Cr(3+), Al(3+), Ga(3+), VO(2+), and Cu(2+). The metal complexes have been studied by UV-vis, CD, NMR, and EPR spectroscopies and mass spectrometry. The formation constants for the iron complex have also been measured and yield a log K(LFe) of 25.3. The Rh and Cr rhizoferrin complexes are unusual in that they appear to adopt a chirality about the metal center that is the opposite of the native iron analog. Several of the alternative metal ion complexes are found to have biological activity toward Morganella morganii in a plate type assay.
