PLSSS HELP!! In the demonstration, Iron reacted with the oxygen in the air. Which one ran out first? How do you know?

Solution 1

It has to be iron because oxygen doesn’t run out unless being used by something like sticking it in a bubble.

DNA is longer than a gene

Question

An atom of oxygen has six electrons in its outermost ring and requires two more to become stable. What is the valence number of oxygen? Question 5 options: +6 +2 –2 –6 +6 +2 –2 –6

Solution 1

Answer: -2

EXPLANATION

Valence refers to the number of electrons that an atom must borrow or lend to complete its outermost shell. An atom of oxygen wants to add two more electrons to complete its outer shell of eight electrons. Since doing so would result in the oxygen atom becoming negatively charged by accepting two more electrons, oxygen is said to have a valence -2

Solution 2

-2

this is the answer

Question

For each solute identify the better solvent: water or carbon tetrachloride Na2, I2, CCH2O, C6H6

Solution 1

NH3 = water (it is actually a water soluble gas)
C6H14 = CCl4 (C6H14 won't mix with water at all)
Na2S = water (Na2S is a salt. Salts dissolve best in water)
Br2 = CCl4, but it will also dissolve in water.

Question

For which of the following reactions is ΔH∘rxn equal to ΔH∘f of the product(s)? Choose all that apply. a. C(s,graphite)+O2(g)→CO2(g) b. Li(s)+12Cl2(g)→LiCl(s) c. Li(s)+12Cl2(l)→LiCl(s) d. 2Li(s)+Cl2(g)→2LiCl(s) e. CO(g)+12O2(g)→CO2(g) f. BaCO3(s)→BaO(s)+CO2(g)

Solution 1

The correct answers are A, B, and D. The ΔHrxn is equal to the ΔHf when the ΔHf of the reactants is zero, and this can only occur when the reactants are pure elements (not compounds) in their natural phase at ambient temperature.

c) Chlorine's natural phase is gaseous, but since it is a liquid in this reaction, ΔHf ≠ 0.

e) CO is a compound, not a pure element.

f) BaCO3 is a compound, not a pure element.

Solution 2

The following reactions is ΔH∘rxn equal to ΔH∘f of the product(s) : option a, b and d

Further explanation

The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation

The enthalpy of formation measured in standard conditions (25 ° C, 1 atm) is called the standard enthalpy of formation (ΔHf °)

Determination of the enthalpy of formation of a reaction can be through a calorimetric experiment, based on the principle of Hess's Law, enthalpy of formation table, or from bond energy data

Delta H reaction (ΔH) is the amount of heat / heat change between the system and its environment

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)

The value of ° H ° can be calculated from the change in enthalpy of standard formation:

∆H ° rxn = ∑n ∆Hf ° (product) - ∑n ∆Hf ° (reactants)

ΔH∘rxn = ΔH∘f of the product(s) if ∆Hf ° (reactants) = 0

The elements in standard conditions are not included in the enthalpy calculations because the enthalpy of those elements under the standard conditions is zero.

a.ΔH°rxn = ∆Hf ° CO₂(∆Hf °C and ∆Hf °O₂ =0)

b.ΔH°rxn = ∆Hf ° LiCl(∆Hf °Li and ∆Hf °Cl₂=0)

c.ΔH°rxn = ∆Hf ° LiCl- 12∆Hf° Cl₂

d. ΔH°rxn = 2∆Hf °LiCl (∆Hf °Li and ∆Hf °Cl₂=0)

e. ΔH°rxn = ∆Hf °CO₂ - ∆Hf °CO

f. ΔH°rxn = ∆Hf °CO₂ + ∆Hf °BaO - ∆Hf ° BaCO₃
