emmainna [20.7K]

Answer:

$4Al(OH)_{3}(s)+3C(s)\rightarrow 4Al(s)+3CO_{2}(g)+6H_{2}O(g)$

Explanation:

The steps involved in the extraction Al from Al(OH)3 are:

Step 1:

$2Al(OH)_{3}(s)\rightarrow Al_{2}O_{3}(s)+3H_{2}O(g)$

Step 2:

$2Al_{2}O_{3}(s)+3C(s)\rightarrow 4Al(s)+3CO_{2}(g)$

The net reaction which shows the extraction of Al from Al(OH)3 can be obtained by multiplying step 1 by a factor of 2 then adding it with step 2

Net reaction = Step 1 * 2 + Step 3

$4Al(OH)_{3}(s)\rightarrow 2Al_{2}O_{3}(s)+6H_{2}O(g)$

+ $2Al_{2}O_{3}(s)+3C(s)\rightarrow 4Al(s)+3CO_{2}(g)$

-------------------------------------------------------------------------------------

$4Al(OH)_{3}(s)+3C(s)\rightarrow 4Al(s)+3CO_{2}(g)+6H_{2}O(g)$

How many moles of oxygen are needed to produce 2 moles of Tetraphosphorus decaoxide (P4O10) in the reaction?

m_a_m_a [10]

Answer:

Explanation:

5 moles of oxygen are needed to produce 1 mols of P4O10

x moles of oxygen are needed to produce 2 mols of P4O10

5/x = 1/2 Cross multiply

1*x = 2 * 5 Combine

x = 10

An FM radio station broadcasts electromagnetic radiation at a frequency of 103.4 MHz (megahertz; MHz =106sâ€“1). Calculate the w

kap26 [50]

Answer:

$Wavelength=2.899\ m$

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength$

c is the speed of light having value $2.998\times 10^8\ m/s$

Given, Frequency = 103.4 MHz = $103.4\times 10^{6}\ Hz$ ( as 1 MHz = 10⁶ Hz)

Thus, Wavelength is:

$Wavelength=\frac{c}{Frequency}$

$Wavelength=\frac{2.998\times 10^8}{103.4\times 10^{6}}\ m$

$Wavelength=2.899\ m$
