Answer:

The ΔH for the formation of 0.490 mol of AgCl is - 32.095 kJ.

Explanation:

Ag⁺(aq)+Cl⁻(aq)→ AgCl(s) ΔH=−65.5kJ

We need to consider that the value of ΔH given is for each mol of AgCl formed.

1 mol AgCl ________________ - 65.5 kJ

0.490 mol AgCl ____________      x

x = - 32.095 kJ

The balloon Spirit of Freedom, flown around the world by American Steve Fossett in 2002, contained 550,000 cubic feet of helium.
Elodia [21]
Assuming the balloon initially has volume of 0 when deflated, the total P(deltaV) = (1.00 atm)(550,000 ft^3) = 550,000 atm-ft^3. To convert into work units, we can first convert ft^3 to L:
(550,000 atm-ft^3)(1 m/3.28 ft)^3
= (15,586.2 atm-m^3)
Then we convert to L:
(15,586.2 atm-m^3)(1000 L/m^3)
= 15,586,200 atm-L
Then we convert to J:
(15,586,200 atm-L)(101.325 J / 1 atm-L)
= 1.579 x 10^9 J

The density of water at 4 degrees Celsius is 1.00 g/cm cubed at unknown object has density of 7.9 g/cm cubed would you expect it
NNADVOKAT [17]

Answer:

The object will be sank

Explanation:

In this case the object is more dense than water.

Density is the relationship between a certain amount of mass of matter and the volume that is being occupied by it.

The object occupies more volume, so it occupies more mass.

As the mass from the object is higher, the object will be sank because the weight is higher than the weight from the liquid.

If the object has a lower density than the water, it will float on it.

The pH of a vinegar solution is 4.15. What is the H3O+ concentration of the solution?
riadik2000 [5.3K]
PH = -log [H3O+]
4.15 = -log [H3O+]
[H3O+] = 10^(-4.15)
[H3O+]= 7.08 × 10^-5
