Ice is simply just frozen water, so it's formula would be the same was water: H2O

H2O because ice is water and freezing is a physical reaction which doesn't changes the substances chemical formula

An equilibrium mixture contains 0.750 mol of each of the products (carbon dioxide and hydrogen gas) and 0.200 mol of each of the

sasho [114]

1.302 moles of carbon dioxide would have to be added

<h3>Further explanation</h3>

The equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient

The equilibrium constant is based on the concentration (Kc) in a reaction

pA + qB -----> mC + nD

$\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}$

While the equilibrium constant is based on partial pressure

$\large {\boxed {\bold {Kp ~ = ~ \frac {[pC] ^ m [pD] ^ n} {[pA] ^ p [pB] ^ q}}}}$

The value of Kp and Kc can be linked to the formula '

$\large {\boxed {\bold {Kp ~ = ~ Kc. (R.T) ^ {\Delta n}}}}$

R = gas constant = 0.0821 L.atm / mol.K

=n = number of product coefficients-number of reactant coefficients

An equilibrium mixture: 0.750 moles of CO2 and H2, and 0.200 moles of CO and H2O

We determine Kc (constant concentration)

$\displaystyle Kc=\frac{0.75.0.75}{0.2.0.2}\\\\Kc=14.1$

the amount of carbon monoxide to 0.300 mol

Reaction :

CO +H₂O ⇔ CO₂ + H₂

initially 0.2 0.2 0.75+x 0.75

reaction 0.1 0.1 0.1 0.1

product 0.3 0.3 0.65+x 0.65

$\displaystyle Kc=\frac{(0.650+x)(0.65)}{0.3.0.3}\\\\14.1(0.09)=0.4225+0.65x\\\\1.269-0.4225=0.65x\\\\0.8465=0.65x\\\\x=1.302$

The nuclear mass of 56fe is 55.9207 amu. calculate the binding energy per nucleon for 56fe.

Aneli [31]

Fe (iron) has 26 protons,30 neutrons and 26 electrons. In order to calculate the binding energy, first you need to find the total mass of all particles in the nucleus:

<span>
<span>26 x mass of proton + 30 x mass of neutron ( all in a.m.u.) = say "m" </span></span>

<span>
Mass defect is m- 55.9207 amu, then convert it into grams and put in equation E = mc2 to get binding energy of Fe.</span>

<span> Divide it by number of nucleons to get binding energy per nucleon</span>.
