write down the way you had to behave to illustrate the behavior of particles as a gas condenses to form a liquid

1 answer:

3 0

Gases near together and vibrate in position however, don't circulate beyond each other. In a liquid, the particles are interested in every different but now not as a great deal as they may be in a strong.

The particles of a liquid are near together, constantly transferring, and may slide beyond one another. The Kinetic-molecular concept attempts to explain the behavior of fuel molecules based totally on the nature of gasoline. The principle is grounded on simple assumptions

In gases the debris passes swiftly in all directions, regularly colliding with every different facet of the box. With a boom in temperature, the debris gains kinetic strength and passes more quickly. Gasoline is a state of matter that has no constant form and no fixed extent. Gases have a decreased density than other states of the count, together with solids and liquids. there may be a high-quality deal of empty area between debris, that have loads of kinetic energy and aren't especially drawn to one another.

Question 20 (2 points)

sveta [45]

Answer:

becomes runoff and finds its way back to the ocean

Explanation:

Precipitation refers to rainfall that reaches the earth.

Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.

When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.

Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean

1) When 2.38g of magnesium is added to 25.0cm of 2.27 M hydrochloric acid, hydrogen gas is released.

Andrej [43]

Answer:

a. HCl.

b. 0.057 g.

c. 1.69 g.

d. 77 %.

Explanation:

Hello!

In this case, since the reaction between magnesium and hydrochloric acid is:

$Mg+2HCl\rightarrow MgCl_2+H_2$

Whereas there is 1:2 mole ratio between them.

a) Here, we can identify the limiting reactant as that yielded the fewest moles of hydrogen gas product via the 1:1 and 2:1 mole ratios:

$n_{H_2}^{by\ HCl}=0.025L*2.27\frac{molHCl}{1L}*\frac{1molH_2}{2molHCl} =0.0284molH_2\\\\n_{H_2}^{by\ Mg}=2.38gMg*\frac{1molMg}{24.3gMg}*\frac{1molH_2}{1molMg}=0.0979molH_2$

Thus, since hydrochloric yields fewer moles of hydrogen than magnesium, we realize it is the limiting reactant.

b) Here, we use the molar mass of gaseous hydrogen (2.02 g/mol) to compute the mass:

$m_{H_2}=0.0284molH_2*\frac{2.02gH_2}{1molH_2}=0.057gH_2$

c) Here, we compute the mass of magnesium associated with the yielded 0.0248 moles of hydrogen:

$m_{Mg}^{reacted}=0.0284molH_2*\frac{1molMg}{1molH_2}*\frac{24.3gMg}{1molMg} =0.690gMg$

Thus, the mass of excess magnesium turns out:

$m_{Mg}^{excess}=2.38g-0.690g=1.69gMg$

d) Finally, we compute the percent yield, considering 0.044 g is the actual yield and 0.057 g the theoretical yield:

$Y=\frac{0.044g}{0.057g} *100\%\\\\Y=77\%$
