How many grams of sucrose, C12H22O11, are in a 94.2 mL sample of a 2.6 M sucrose solution?

Answers

Answer 1

Answer: get the mass # of each element since its asking for grams
C- 12.011x12
H-1.008x22
O- 15.999x11
add all of those together to get the mass
put 2.6 moles on the top - so its the mass x 2.6 then divide by 94.2 Ml

Answer 2

Answer: Molar (M) means mol of solute in volume of solution (expressed by liters):

$2.6(mol)/(L)\cdot 94.2\cdot 10^(-3)\ L = 0.245\ mol$

The molecular weight of sucrose is: 12·12 + 22·1 + 11·16 = 342 g/mol.

$0.245\ mol\ C_(12)H_(22)O_(11)\cdot (342\ g)/(1\ mol) = \bf 83.79\ g\ C_(12)H_(22)O_(11)$

Which substance increases in solubility as the temperature decreases? 1) KClO3
2) NH3
3) KNO3
4) NaCl

Answers

Answer:

The correct answer is 2.

Explanation:

The NH3 solubility curve shows that when the temperature increases, the solubility of the compound decreases. The molecule is not flat but has a tetrahedral shape with a vacant vertex, and this is due to the formation of hybrid sp³ orbitals. Unlike other compounds, the NH3 solubility curve has been experimentally tested and is attached for better understanding.

Have a nice day!

NH₃ would. This is because of the fact that ammonia is a molecular gas while the other options are ionic crystals. Crystals increase in solubility when the temperature increases while gases increase in solubility while temperatures deceases.

Which statement explains why the bonds between nonmetals tend to be covalent? The bonds are found to be nondirectional. They have large differences in electronegativity. They have small differences in electronegativity. They have ions that produce an electrostatic pull.

Answers

Correct Answer: They have small differences in electronegativity (statement 3)
Reason:
The nature of chemical bond between atoms is primarily driven by the electronegativity difference between constituent atoms. If electronegativity difference between constituent atoms is significantly higher, ionic bond formation is preferred. On other hand, low difference in electronegativity values, favours formation of covalent bond.

Given the reaction below: N2O4 (g) ⇌ 2 NO2 (g)Kc= 4.2
What is the equilibrium concentration of N2O4 if the equilibrium concentration of NO2 is 0.785 M?

Answers

N₂O₄ (g) ⇌ 2 NO₂ (g)

Kc = [ NO₂ ]² / [ N₂O₄ ]

4.2 = [ 0.785 ] [ N₂O₄ ]

[ N₂O₄ ] = 4.2 / 0.785

[N₂O₄ ] = 5.350 M
