Answer:

yeild solid iron

Explanation:

When two solutions of ionic compounds are mixed, a solid may form. This type of reaction is called a precipitation reaction, and the solid produced in the reaction is known as the precipitate.

How many particles can be stored in a 4.0 L container at room temperature (23 C) and standard atmospheric pressure

velikii [3]

Answer: 9.91×10²³ particles

Explanation:

To find the amount of particles, you will need to use the Ideal Gas Law with what we are given.

Ideal Gas Law: PV=nRT

After we find moles, we can use Avogadro's number to convert to particles.

$n=\frac{PV}{RT}$

P=101.3kPa=1.00 atm

V=4.0 L

T=23°C+273.15=296.15 K

R=0.08206 Latm/Kmol

$n=\frac{(1.00 atm)(4.0 L)}{(0.08206Latm/Kmol)(296.15K)}$

$n=0.164595 mol$

Now that we have moles, we can convert to particles.

$0.164595mol*\frac{6.022*10^2^3 particles}{mol} =9.91*10^2^2 particles$

Calculate the volume of 12.0 g of helium at 100°c and 1.2 atm

hodyreva [135]

Volume = nRT/P

n = number of particles (moles)

R = universal gas constant (0.0821)

T = temperature (Kelvin)

P = pressure (atm)

(Assuming you have 1 mole of Helium in a chemical reaction) We would need to convert grams to moles: 12.0g He x 1 mol He/4 molar mass of He = 3 mol He

Convert Celsius to Kelvin: 100*C + 273.15 = 373.15 K

Now we can set up the equation for volume: (3mol)(0.0821)(373.15)/1.2atm = 76.6 L of Helium gas
