Answer:

Explanation:

The boiling point of oxygen is -182.96 degrees Celsius (under 1 standard atmosphere). This means at temperatures below that point, oxygen is a solid or a liquid, and at temperatures above that point, oxygen is a gas. So at -183 degrees Celsius, oxygen is a liquid.

Inessa [10]

Answer:

The molar concentration of the final solution is 1.71 $\frac{moles}{liter}$

Explanation:

Molarity is a way of expressing the concentration of solutions and indicates the number of moles of solute dissolved per liter of solution.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.:

$Molarity (M)=\frac{number of moles of solute}{volume}$

Molarity is expressed in units ( $\frac{moles}{liter}$ ).

Then, the number of moles of solute can be calculated as:

number of moles of solute= molarity* volume

So, in this case, the final concentration can be calculated as:

$Final molarity (M)=\frac{Total number of moles of solute}{Total volume}$

where, being 65 mL=0.065 L, 125 mL=0.125 L and 190 mL=0.190 L (because 1000 mL= 1 L):

Total number of moles of solute= 0.065 L*0.513 $\frac{moles}{liter}$ + 0.125 L*2.33 $\frac{moles}{liter}$ = 0.033345 moles + 0.29125 moles= 0.324595 moles
Total volume= 65 mL + 125 mL= 190 mL= 0.190 L

Replacing:

$Final molarity (M)=\frac{0.324595 moles}{0.190 L}$

Final molarity ≅ 1.71 $\frac{moles}{liter}$

The molar concentration of the final solution is 1.71 $\frac{moles}{liter}$

Using the reaction C12H22O11 + 12 O2 ->12CO2 + 11H2O (e). How many grams of carbon dioxide can be produced from 456.7g sucros

klio [65]

Answer:

704.6 g CO2

Explanation:

MM sucrose = 342.3 g/mol

MM CO2 = 44.01 g/mol

g CO2 = 456.7 g sucrose x (1 mol sucrose/MM sucrose) x (12 moles CO2/1 mol sucrose) x (MM CO2/1mol CO2) = 704.6 g CO2
