Answer:

Gas to Solid

Explanation:

A condensation reaction goes from gas to solid

Condensation is a physical change which alters the physical properties of matter particularly the form and state. In a condensation reaction, a gas goes from solid to liquid.

It is the inverse of the sublimation reaction.

  • It involves the loss in energy by a gas.
  • When gases lose energy, they become pulled together by attractive forces.
  • This changes their state to solid with enough loss in energy.

Assuming all volume measurements are made at the same temperature and pressure, how many liters of water vapor can be produced w
maria [59]
For the reaction 2 K + F2 --> 2 KF,
consider K atomic wt. = 39
23.5 g of K = 0.603 moles, hence following the molar ratio of the balanced equation, 0.603 moles of potassium will use 0.3015 moles of F2. (number of moles, n = 0.3015)

Now, following the ideal gas equation, PV = nRT
P = 0.98 atm
V = unknown
n = 0.3015 moles
R = 82.057 cm^3 atm K^-1mole^-1 (unit of R chosen to match the units of other parameters; see the reference below)
T = 298 K
Solving for V,
V = (nRT)/P = (0.3015 mol * 82.057 cm^3 atm K^-1 mol^-1 * 298 K)/(0.98 atm)
solve it to get 7517.6 cm^3 as the volume of F2 = 7.5176 liters of F2 gas is needed.


2. Use the formula: volume1 * concentration 1 = volume 2 * concentration 2
where, volume 1 and concentration 1 are for solution 1 and volume 2 and solution 2 for solution 2.

Solution 1 = 12.3 M NaOH solution
Solution 2 = 1.2 M NaOH solution

<span> Solving for volume 1, volume 1 = (12.4 L * 1.2 M)/12.3 M = 0.1366 L  </span>

Explain what happens to the heat that is being added to a substance when the substance is changing phase.
nekit [7.7K]
<span>When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase. For example, ice melts and becomes water; water evaporates and becomes water vapor.These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.</span>

A hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place over the next fe
Fantom [35]

Answer:

A

Explanation:

The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.
