Mix it. The salt will dissolve, eventually the sand and metal will settle. Pour out most of the water, let it evaporate leaving the salt. Use a magnet for the iron, which leaves the sand.

Finger [1]

Answer:

3.0 L O₂

Explanation:

If CO reacts at STP, it means that there are 1.0 moles of CO. To find the moles of O₂, you need to use the mole-to-mole ratio from the given equation.

1.0 moles CO            1 mole O₂
----------------------  x  ---------------------  =  0.5 moles O₂
                                2 moles CO

To calculate the liters of oxygen, you need to use Avogadro's Law:

V₁ / N₁ = V₂ / N₂

In this equation, "V₁" and "N₁" represent the volume and moles of the first molecule. "V₂" and "N₂" represent the volume and moles of the second molecule. You can plug the given and calculated values into the equation and simplify to isolate V₂.

V₁ = 6.0 L                     V₂ = ? L

N₁ = 1.0 moles              N₂ = 0.5 moles

V₁ / N₁ = V₂ / N₂                                            <----- Avogadro's Law

(6.0 L) / (1.0 moles) = V₂ / (0.5 moles)         <----- Insert values

6.0 = V₂ / (0.5 moles)                                   <----- Simplify left side

3.0 = V₂                                                         <----- Multiply both sides by 0.5

What is the initial temperature (in Celsius) of a 675 ml balloon if the
RoseWind [281]

Answer: 127 (3.s.f)

Explanation:

Boyle's law states that Volume x pressure = constant

Therefore let's first find the constant: 45 x 1900 = 85500

Then lets plug 675 ml and 85500 into the equation above:

675 x C = 85500

C = 127 (3 s.f.)
