A balloon that had a volume of 3.50 L at 25.0°C is placed in a hot room at 40.0°C. If the pressure remains constant at 1.00 atm,

choli [55]

Answer:

3.676 L.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n and P are constant, and have different values of V and T:

(V₁T₂) = (V₂T₁)

Knowing that:

V₁ = 3.5 L, T₁ = 25°C + 273 = 298 K,

V₂ = ??? L, T₂ = 40°C + 273 = 313 K,

Applying in the above equation

(V₁T₂) = (V₂T₁)

∴ V₂ = (V₁T₂)/(T₁) = (3.5 L)(313 K)/(298 K) = 3.676 L.

Iron is obtained by reducing iron (III) oxide using the gas carbon monoxide. The reaction is

ivann1987 [24]

A. iron(III) oxide + Carbon-monoxide -> Iron + Carbon-di-oxide.
b.56*2 +16*3
c.Moles=mass(g) / Mr which is 3200/160
d. 2 moles
e.2 moles
f. Moles x Mr = mass so, 20 x 112=2240g

What determines the strength of a dipole-dipole force?

7nadin3 [17]

Answer:

hope this helps you :)

Explanation:

Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole-induced dipole forces.
