Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C

(s) 2 H2O (l) --> CH4 (g) CO2 (g) What mass in grams of carbon is required to react with water to form 1.00 mol CH4

Answer:

24 g of C are needed to produce 1mol of CH₄

Explanation:

The reaction is:

2C (s) +  2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g

1.50μm2. Convert this to square meters.
mars1129 [50]
Based on the standards of units conversion, to convert from micrometer to meter, we multiply by 10^-6.
Since we there is a square (10^2) to consider, then to convert from micrometer squared to meter squared, we will multiply by (10^-6)^2 as follows:
1.5 <span>μm2 = 1.5 x (10^-6)^2 = 1.5 x 10^-12 meter sqaures</span>

Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because they carry enough energy to b
Kamila [148]

Answer:

344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.

Explanation:

C-C(g)\rightarrow 2C(g) ,ΔH = 348 kJ/mol

Energy required to break 1 mole of C-C bond = 348 kJ

Energy required to break 1 C-C bond = E

E = \frac{348,000J}{6.022\times 10^{23}}=5.779\times 10^{-19} J

Energy related with the wavelength of light is given by Planck's equation:

E=\frac{hc}{\lambda }

\lambda =\frac{hc}{E}

=\frac{6.626\times 10^{-34} Js\times 3\times 10^8 m/s}{5.779\times 10^{-19} J}

\lambda =3.44\times 10^{-7} m = 344 nm

1 m =10^9 nm

344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.
