6 0

Explanation:

Density = 1.60 g/mL

Initial Temperature T1 = 218.0°C + 273 = 491 K (Upon converting to kelvin temperature)

Final Temperature T2 = 750.0°C + 273 = 1023 K (Upon converting to kelvin temperature)

Mass of gas = 1.00 lb = 453.592 g (Upon converting to g)

Final Volume V2 = ?

Initial volume can be obtained from;

Density = Mass / Volume

Volume = Mass / Density

Volume = 453.592 / 1.60 = 283.495 ml

Initial Volume V1 = 283.495 ml

Using charles law;

V1 / T1 = V2 / T2

V2 = V1 * T2 / T1

V2 = 283.495 * 1023 / 491

V2 = 590.66 ml

At-57 °C and 1 atm, carbon dioxide is in which phase? View Available Hint(s) Phase diagrams for water (Figure 1)and carbon dioxi

goblinko [34]

Answer:

Gas

Increase the pressure

Explanation:

Let's refer to the attached phase diagram for CO₂ (not to scale).

<em>At -57 °C and 1 atm, carbon dioxide is in which phase?</em>

If we look at the intersection between -57°C and 1 atm, we can see that CO₂ is in the gas phase.

<em>At 10°C and 2 atm carbon dioxide is in the gas phase. From these conditions, how could the gaseous CO₂ be converted into liquid CO₂?</em>

Since at 10°C and 2 atm carbon dioxide is below the triple point, the only way to convert it into liquid is by increasing the pressure (moving up in the vertical direction).

What is the molarity of the potassium hydroxide if 25.25 mL of KOH is required to neutralize 0.500 g of oxalic acid, H2C2O4? H2C

Greeley [361]

Answer:

0.444 mol/L

Explanation:

First step is to find the number of moles of oxalic acid.

n(oxalic acid) = $\frac{0.5g}{90.03 g/mol} = 5.5537*10^{-3} mol\\$

Now use the molar ratio to find how many moles of NaOH would be required to neutralize $5.5537*10^{-3} mol\\$ of oxalic acid.

n(oxalic acid): n(potassium hydroxide)

1 : 2 (we get this from the balanced equation)

$5.5537*10^{-3} mol\\$ : x

x = 0.0111 mol

Now to calculate what concentration of KOH that would be in 25 mL of water:

$c = \frac{number of moles}{volume} = \frac{0.0111}{0.025} = 0.444 mol/L$
