How many moles of calcium chloride are needed to produce 6.50 moles of sodium chloride?
Anit [1.1K]

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because an equation to show the production of sodium chloride from calcium chloride should have been illustrated. However, if the balanced chemical equation showing sodium chloride (NaCl) been a product of a reaction involving calcium chloride (CaCl₂) as a reactant (shown below) is to be used, then we start by writing a complete balanced chemical equation

CaCl₂ + Na₂CO₃  ⇒   CaCO₃ + 2NaCl

From the equation above, it can be deduced that 1 mole of CaCl₂ is required to produce 2 moles of NaCl, thus how many moles of CaCl₂ will be required to produce 6.5 moles of NaCl.

1 mole of CaCl₂ = 2 moles of NaCl

? moles of CaCl₂ = 6.5 moles of NaCl

cross multiply

? moles of CaCl₂ = 6.5 × 1/2

? moles of CaCl₂ = 3.25 moles of CaCl₂

3.25 moles of CaCl₂ will be needed to produce 6.5 moles of NaCl

After pyruvate oxidation, the chemical energy of how many carbons of the original glucose molecule is converted to chemical ener
Mars2501 [29]
I believe the answer is 4 carbons. Glycolysis involves break down of glucose to two molecules of pyruvic acid (3 carbons) under aerobic conditions. At the end of glycolysis the two pyruvate molecules undergoes pyruvate oxidation to capture the remaining energy in the form of ATP. A carboxyl group is removed from pyruvate and released in the form carbon dioxide, leaving a two carbon molecule  which forms Acetyl-CoA (2 molecules). Acetyl-CoA then serves as a fuel for the citric acid cycle in the next stage of cellular respiration.

A 255 mL round--bonom flask is weighed and found to have a mass of 114.85 g. A few millimeters of an easily vaporized liquid are
Alex17521 [72]

Answer: Option (d) is the correct answer.

Explanation:

According to the given situation, mass of compound will be calculated as follows.

Mass of compound = mass of flask and condensed vapor - mass of flask

                                 = 115.23 - 114.85

                                = 0.38 g

Volume (V) = 255 mL = 255 \times 10^{-6} m^{3}        (as 1 ml = 10^{-6} m^{3})

Pressure (P) = 101325 Pa

Temperature = 100^{o}C = (100 + 273) K = 373 K

Now, according to the ideal gas equation, PV = nRT

and, moles of compound n = \frac{PV}{RT}

                     = \frac{101325 \times 255 \times 10^{-6}}{8.314 \times 373}

                     = 0.008332 mol

As, molar mass of compound = \frac{mass}{\text{no. of moles}}

                                                  = \frac{0.38}{0.008332}

                                                  = 46 g/mol

Therefore, the compound is C_{2}H_{5}OH (molar mass = 12 x 2 + 5 x 1 + 16 + 1 = 46 g/mol).

Thus, we can conclude that out of the given options the liquid could be C_{2}H_{5}OH.
