Answer: This is an oxidation-reduction (redox) reaction:

3 C-II - 12 e- → 3 CII (oxidation)

4 CrVI + 12 e- → 4 CrIII (reduction)

C2H5OH is a reducing agent, K2Cr2O7 is an oxidizing agent.

How many grams are in 0.35 moles of C2H4? please show dimensional analysis
fredd [130]

Answer:

9.8g

Explanation:

Using periodic table find molar mass of C and H:

C=12.01g/mol

H=1.008g/mol

Molar mass of C2H4=(12.01)2+(1.008)4=28.03g/mol

Using molar mass times moles of the chemical to find the mass in 0.35 moles of c2h4:

28.03 x 0.35=9.8grams

What is the relative formula mass of N2O? Ar of N = 14 and Ar of O = 16.
s2008m [1.1K]

We have to calculate formula mass of N₂O.

The answer is: 44

Relative formula mass is the sum of relative atomic mass of constituent atoms in a formula unit of any compound.  Relative formula mass is represented as same symbol of relative molecular mass.

To calculate relative formula mass we need to know number of each atom in the formula and then adding atomic masses of all the atoms.

In N₂O, number of N-atom present is equal to 2 and number of O-atom is equal to  1.

Atomic mass of N-atom is 14 and atomic mass of O-atom is 16.

So, formula mass of N₂O is (2 X 14)+16 = 44.

On the basis of the information below, the dissolution of FeF2(s) in acidic solution is A. thermodynamically favorable, because
antoniya [11.8K]

Since K3 is greater than 1, the reaction is thermodynamically favorable.

Data;

  • FeF2 is in an acidic solution
  • K2 > 1 is thermodynamically favorable
  • k3 > 1 is not thermodynamically favorable
  • K1<1 is not thermodynamically favorable

<h3>Hess Law</h3>

This states that the heat change in a given chemical reaction is the same irrespective of the number of process in which the reaction is effected.

Using Hess Law;

rxn_3 = rxn_1 * 2rxn_2\\k_3 = k_1 * k_2^2\\k_3 = 2*10^-^6 * (1*10^3)^2\\k_3 = 2

substituting this using Gibbs law,

\delta G^0_3 = -RT\ln K_3\\\delta G^0_3 < 0

Since K3 is greater than 1, the reaction is thermodynamically favorable.
