1) Reaction is exothermic because energy of products is less than energy of reactants

2) Energy is released because the reaction is exothermic

3) 350

4) 150

5) 500-350=150

6) 350-150=200

0.65 moles of O2 originally at 85°C is cooled

soldier1979 [14.2K]

Answer:

2.09 atm

Explanation:

We can solve this problem by using the equation of state for an ideal gas, which relates the pressure, the volume and the temperature of an ideal gas:

$pV=nRT$

where

p is the pressure of the gas

V is its volume

n is the number of moles

R is the gas constant

T is the absolute temperature

In this problem we have:

n = 0.65 mol is the number of moles of the gas

V = 8.0 L is the final volume of the gas

$T=40C+273=313 K$ is the temperature of the gas

$R=0.082 atm L mol^{-1} K^{-1}$ is the gas constant

Solving for p, we find the final pressure of the gas:

$p=\frac{nRT}{V}=\frac{(0.65)(0.082)(313)}{8.0}=2.09 atm$

Classify each of the following possible reactions according to whether a precipitate will form or will not form.

elena-14-01-66 [18.8K]

Answer:

Reactions, 2, 3 and 5 make precipitates

Explanation:

1. The halogens always make aqueous salts with elements from group 1

2. Phosphate anion can make insoluble salts, the same as carbonate.

3. Nitrate anion always make aqueous salts

4. Sulfate anion makes aqueous salts except with Ag⁺, Pb⁺² and group 2

1. KI(aq) + NaCl(aq) → KCl(aq) + NaI(aq)

2. 2Na₃PO₄ (aq) + 3CoCl₂(aq) → 6NaCl(aq) + Co₃(PO₄)₂(s) ↓

3. Na₂CO₃ (aq) + CuCl₂ (aq) → 2NaCl (aq) + CuCO₃ (s) ↓

4. 2LiNO₃ (aq) + Na₂SO₄ (aq) → Li₂SO₄ (aq) + 2NaNO₃(aq)

5. CrCl₂ (aq) + Li₂CO₃ (aq) → 2LiCl (aq) + Cr₂(CO₃)₂ (s) ↓
