Option A: Clouds
In the morning, air is cool and as sun begins to rise it starts increasing the temperature of air. By time, the air becomes warmer and warmer. Depending upon the surrounding conditions, air in different areas heat up at different rates.
Due to this heating, thermal formation takes place, this is due to uneven heating of surface of earth. The thermal formation at surface causes difference in temperature of surface of the earth and air around it. The warm air has tendency to rise thus, the air in the thermal rise and expand. Due to expansion it cools down, this process continues till the temperature of thermal air reaches equals to the temperature of surrounding air. This results in the formation of cloud.
Thus, when a humid air mass rises into a cooler temperature area, clouds formation takes place
Answer:
Yes, there will be liquid present and the mass is 5.19 g
Explanation:
In order to do this, we need to use the equation of an ideal gas which is:
<em>PV = nRT (1)</em>
<em>Where:</em>
<em>P: Pressure</em>
<em>V: Volume</em>
<em>n: number of moles</em>
<em>R: gas constant</em>
<em>T: Temperature</em>
we know that the pressure is 856 Torr at 300 K. So, if we want to know if there'll be any liquid present, we need to calculate the moles and mass of the CCl3F at this pressure and temperature, and then, compare it to the initial mass of 11.5 g.
From (1), solving for moles we have:
<em>n = PV/RT (2)</em>
Solving for n:
P = 856/760 = 1.13 atm
R = 0.082 L atm / mol K
n = 1.13 * 1 / 0.082 * 300
n = 0.0459 moles
Now, the mass is:
m = n * MM (3)
The molar mass of CCl3F reported is 137.37 g/mol so:
m = 0.0459 * 137.37
m = 6.31 g
Finally, this means that if we put 11.5 g of CCl3F in a container, only 6.31 g will become gaseous, so, this means it will be liquid present, and the mass is:
m = 11.5 - 6.31
m = 5.19 g
Centimeters are units of length.
Answer:
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound
The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) = 5
<h3>What in an atomic number?</h3>
the number assigned to a chemical element according to its atomic number in the periodic system, which places the elements in ascending order of the number of protons in their nuclei. As a result, the atomic number is also the number of protons, which in a neutral atom is always equal to the amount of electrons.
<h3>Briefing:</h3>
Protons and neutrons are added to determine an element's mass number. The only number that may change while maintaining the identity of an element is the number of neutrons for that element (because the atomic number is the number of protons).
Mass number = protons + neutrons
<h3>According to the given data;</h3>
Given:
5 protons,
6 neutrons
2 electrons
Atomic number = ?
We know that the Mass number = protons + neutrons:
Mass number = protons + neutrons
Mass number = 5 + 6:
Mass number = 11
The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) = 5.
