The amount of water that will be produced is 50.36 grams

<h3>Stoichiometric problems</h3>

The metabolism of glucose is represented by the following equation:

$C_6H_1_2O_6(s)+6O_2(g)--- > 6CO_2(g)+6H_2O(g)$

The mole ratio of glucose metabolized to the water produced is 1:6.

Mole of 84.0 g glucose = 84/180.156 = 0.4662 moles

Equivalent mole of water = 0.4662 x 6 = 2.7975 moles

Mass of 2.7975 moles water = 2.7975 x 18 = 50.36 grams

The reaction of iron (III) oxide with carbon monoxide produces iron and carbon dioxide.

True [87]

Answer:

21g

Explanation:

no.ofmol fe2o3=39.5/(56×2+16×3)=0.25mol

from equation 1mole fe2o3 react with 3mole co

so,0.25mol fe2o3 react with 0.75mol co

mass of co=0.75×(12+16)=21g

The carbon-carbon (C―C) bond has an average bond energy of 347 kJ/mol, which is the energy required to break one mole of C―C bon

olganol [36]

Answer:

(3) 345 nm

Explanation:

<u>Given:</u>

Average C-C bond energy = 347 kJ/mol

<u>To determine:</u>

Wavelength of photon that can break a C-C bond

<u>Calculation:</u>

The energy (E) of a photon is related to its wavelength (λ) by the Planck's equation:

$E = \frac{hc}{\lambda }$

where h = Planck's constant = 6.626*10⁻³⁴ Js

c = speed of light = 3*10⁸ m/s

$\lambda = \frac{hc}{E}$

$\lambda =\frac{6.626*10^{-34}Js*3*10^{8}ms^{-1}*6.023*10^{23}mol^{-1}}{347,000Jmol^{-1}}$

λ = 3.45*10⁻⁷ m

Since 1 nanometer (nm) = 10⁻⁹ m

The calculated wavelength corresponds to 345 nm

Why was a condenser not necessary in the final distillation

Travka [436]

Answer:Methyl benzoate has a very high boiling point i.e. 199°C.Therefore a water-cooled condenser is not advisable as it might crack the condenser tube.So in such cases air condenser tube is normally used for such distillation procedure.

5. Calculate the decrease in temperature when 6.00 L at 20.0 °C is compressed to 4.00 L.

Kazeer [188]

Answer: 195.3 K

Explanation: Use Charles Law to get T2

Charles Law V1 / T1 = V2 / T2

Derive the equation to find T2

T2 = V2T1 / V1

Convert temperature into K

T1 = 20.0 °C + 273 = 293 K

Substitute the values:

4.00 L x 293 K / 6.00 L = 195. 3 K
