Describe in detail what you know about the enthalpy, entropy, and free energy changes when a sample of gas condenses to a liquid
ycow [4]
The keyword here is gas condenses to a liquid, which mean we're talking about condensation process

The enthalpy energy in condensation process is negative because it releases energy
The entropy in general will also decreases .

Temperature affect this change because it will create free energy if added with this result

hope this helps

A solution was made by mixing 60.5 g of glucose (C6H12O6) with enough water to make 325 ml of solution. What is the percent (mas
IgorC [24]

mass percent concentration = 15.7 %

molar concentration of glucose solution 1.03 M

Explanation:

To calculate the mass percent concentration of the solution we use the following formula:

concentration = (solute mass / solution mass) × 100

solute mass = 60.5 g

solution mass = solute mass + water mass

solution mass = 60.5 + 325 = 385.5 g (I used the assumption that the solution have a density of 1 g/mL)

concentration = (60.5 / 385.5) × 100 = 15.7 %

Now to calculate the molar concentration (molarity) of the solution we use the following formula:

molar concentration = number of moles / volume (L)

number of moles = mass / molecular weight

number of moles of glucose = 60.5 / 180 = 0.336 moles

molar concentration of glucose solution = 0.336 / 0.325 = 1.03 M

A compound contains 1.10 mol of K, 0.55 mol of Te, and 1.65 mol of O. What is the simplest formula of this compound?
sergiy2304 [10]

Answer:

K_2TeO_3

Explanation:

Given that:-

Moles of K = 1.10 moles

Moles of Te = 0.55 moles

Moles of O = 1.65 moles

Taking the simplest ratio of the moles of the elements as:-

   K : Te : O

1.10 : 0.55 : 1.65  

   2 :     1   : 3

Empirical formulas is the simplest or reduced ratio of the elements in the compound. So, the empirical formula is:- K_2TeO_3

The bond angle for methane is the angle determined by two consecutive hydrogen atoms and the central carbon atom.
snow_tiger [21]

Answer:

a. True

Explanation:

The bond angle for methane is the angle determined by two consecutive hydrogen atoms and the central carbon atom.

Methane, a tetrahedron has the structural formula:

                             H

                              |

                    H  -   C   -  H

                              |

                             H            Methane, CH4

The bond angle is the angle between the H-C-H atoms and is 109.5degrees.
