What is the frequency of a wave traveling at 5,000 m/s with a wavelength of .002 m/cycle?

Chemistry

Answer:

2.5\cdot 10^6 Hz

Explanation:

The relationship between the speed of a wave, its frequency and its wavelength is given by the wave equation:

v=f\lambda

where

v is the wave speed

f is the frequency of the wave, which is the number of cycles completed by the wave in one oscillation

\lambda is the wavelength, which is the distance between two consecutive crests of the wave

For the wave in this problem we have:

v = 5000 m/s is the speed

\lambda=0.002 m is the wavelength of the wave

Solving for f, we find the frequency:

f=\frac{v}{\lambda}=\frac{5000}{0.002}=2.5\cdot 10^6 Hz

For a tablet containing 500. mg of vitamin C, calculate how many ml of 0.095 M NaOH is required to reach the equivalence point.
Gala2k [10]

Answer:

mL of NaOH required =29.9mL

Explanation:

Let us calculate the moles of vitamin C in the tablet:

The molar mass of Vitamin C is 176.14 g/mole

moles=\frac{mass}{molarmass}=\frac{500mg}{176.14}=\frac{0.5}{176.14}=0.0028

Thus we need same number of moles of NaOH to reach the equivalence point.

For NaOH solution:

moles=MolarityXvolume=0.095Xvolume

0.00283=0.095Xvolume

volume=0.0299L=29.9mL

b. Determine the molecular formula of a molecule with an empirical formula NH2and a molar mass of 32 g/mol.
VladimirAG [237]
I'm taking this lesson now, so imma help u ( if u need anything else ask me)

so given Molar mass= 32 g/mol
molar mass= (empirical formula) n
32 = (14x1 + 2x1) n
32 = 16 n , so n= 2
so, molecular formula= N2H4

1. What is the best method for removing water from a hydrated compound?
Helga [31]
The traditional method is to heat the compound in an oven, on a hot plate or over a Bunsen burner. Waters of hydration are loosely bound in the compound and can be driven off at temperatures below the melting point of the compound. So the answer is heating.
