The opportunity costs of working part-time while attending high school could be studying time, grades, and your own free time. It depends on the person, how they do in school, but if it were for me, I would say the benefits outweigh the costs. I have enough time to study and still get good grades in school.

A phosphate buffer solution (25.00 mL sample) used for a growth medium was titrated with 0.1000 M hydrochloric acid. The compone
AysviL [449]

Answer:

0,07448M of phosphate buffer

Explanation:

sodium monohydrogenphosphate (Na₂HP) and sodium dihydrogenphosphate (NaH₂P) react with HCl thus:

Na₂HP + HCl ⇄ NaH₂P + NaCl <em>(1)</em>

NaH₂P + HCl ⇄ H₃P + NaCl <em>(2)</em>

The first endpoint is due the reaction (1), When all phosphate buffer is as NaH₂P form, begins the second reaction. That means that the second endpoint is due the total concentration of phosphate that is obtained thus:

0,01862L of HCl×\frac{0,1000mol}{L}= 1,862x10⁻³moles of HCl ≡ moles of phosphate buffer.

The concentration is:

\frac{1,862x10^{-3}moles}{0,02500L} = <em>0,07448M of phosphate buffer</em>

<em></em>

I hope it helps!

A mercury lamp emits radiation with a frequency of 5.62 x1024 Hz. Calculate the wavelength of
Nitella [24]

Answer:

wavelength = 0.534×10⁻¹⁶ m

Explanation:

Given data:

Frequency of wave = 5.62 ×10²⁴ Hz

Wavelength = ?

Solution:

Speed of photon = wavelength × frequency

wavelength = speed of photon / frequency

Now we will put the values in formula:

wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ Hz

Hz = s⁻¹

wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ s⁻¹

wavelength = 0.534×10⁻¹⁶ m
