Answer:

Iron is extracted from iron ore in a huge container called blast furnace. Iron ores such as Haematite contain iron (III) oxide, Fe 2o3. The oxygen must be removed from the iron (III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reaction.

The molality of a solution containing 8.1 moles of solute in 4,847 g of solvent is _____. 1.7m 598m 39m 0.17m

Hitman42 [59]

When molality = no.of moles of solute/weight Kg of solvent

and when we have the no. of moles of solute = 8.1 moles
and the weight Kg of the solvent =4847 g /1000 = 4.847 Kg
so by substitution :
Molarity = 8.1m / 4.847Kg = 1.67 M

In general the human ear is most sensitive to sounds at 2500 hz. Assuming that sound moves at 330m/s what is the wavelength of s

elena-s [515]

Answer:

0.132 meters is the wavelength of sounds to which people are most sensitive.

Explanation:

Frequency of the sound human ears are most sensitive to = $\nu = 2500Hz=2500 s^{-1}$

Speed of the sound wave = S = 330 m/s

Wavelength of the sound human ears are most sensitive to = $\lambda = ?$

$\nu=\frac{S}{\lambda }$

$2500 s^{-1}=\frac{330 m/s}{\lambda }$

$\lambda =\frac{330 m/s}{2500 s^{-1}}=0.132 m$

0.132 meters is the wavelength of sounds to which people are most sensitive.
