The answer that best completes the statement above is EXTENSIVE LAVA FLOW. Maria is the name that refers to an asteroid family. And this has punctured the surface of the moon which created magma to bleed out and resulted in an extensive lava flow. Hope this answer helps.

N2+3H2=>>2NH3. If 6.72dm³ of each of Nitrogen and hydrogen (measured at S.T.P.) are made to produced Ammonium. Which of th

torisob [31]

Answer:

Hydrogen, 0,2 mol

Explanation:

$V_{M}$ = 22, 4 l/mol

V ( $N_{2}$ ) = 6,72 $dm^{2}$ = 6,72 l

V ( $H_{2}$ ) = 6,72 $dm^{2}$ = 6,72 l

The formula is:

n = $\frac{V}{V_{M} }$

n ( $N_{2}$ ) = 6,72l /22,4 l/mol = 0,3 mol

n ( $H_{2}$ ) = 6,72l /22,4 l/mol = 0,3 mol (the same)

But from the equation we get a proportion that 1 mol ( $N_{2}$ ) - 3 mol ( $H_{2}$ )

$\frac{0,3}{1} > \frac{0,3}{3}$ (we have more hydrogen than is need for the reaction)

So there is excess of $H_{2}$

We only need $\frac{0,3}{3}$ = 0,1 mol ( $H_{2}$ )

0,3 mol (hydrogen quantity we have) - 0,1 mol (hydrogen quantity we need for the reaction) = 0,2 mol (excess)

A solution contains 5.25 g of urea, CO(NH2)2 (a nonvolatile solute) and 0.100 kg of water. If the vapor pressure of pure water a

babymother [125]

Answer:

The vapor pressure of the solution is 23.3 torr

Explanation:

Step 1: Data given

Mass of urea = 5.25 grams

Mass of water = 0.100 kg = 100 grams

Temperature = 25.0 °C

Vapor pressure of water = 23.7 torr

Step 2: Calculate moles of water

Moles H2O = mass H2O / molar mass H2O

Moles H2O = 100 grams / 18.02 g/mol

Moles H2O = 5.55 moles

Step 3: Calculate moles of urea

Moles urea = 5.25 grams / 60.06 g/mol

Moles urea = 0.0874 moles

Step 4: Calculate mol fraction H2O

Mol fraction H2O = 5.55 moles / (5.55 + 0.0874)moles

Mol fraction H2O = 0.984

Step 5: calculate the vapor pressure of the solution

This means that you can use the mole fraction of water and the vapor pressure of pure water at 25° C to determine the vapor pressure of the solution.

Psol =Xwater * Pwater

⇒Psol = the vapor pressure of the solution

⇒Xwater =the mol fraction of water

⇒Pwater = the vapor pressure of pure water

Psol = 0.984 * 23.7 torr

Psol = 23.3 torr

The vapor pressure of the solution is 23.3 torr
