Which statement about atmospheric pressure is false?

Chemistry
2 answers:
Tcecarenko [31]3 years ago
7 0

Answer:

The false statement is "With an increase in altitude, atmospheric pressure increases as well" because "With an increase in altitude, atmospheric pressure decreases."

Explanation:

Altitude is the vertical distance that exists between any given point on Earth and sea level.

The weight of the air that makes up our atmosphere puts pressure on the earth's surface. This pressure is known as atmospheric pressure. Generally, the more air there is over an area, the higher the atmospheric pressure. This means that atmospheric pressure changes with altitude: the higher the height of the Earth's surface with respect to sea level (altitude), the lower the air pressure.

So, <u><em>the false statement is "With an increase in altitude, atmospheric pressure increases as well" because "With an increase in altitude, atmospheric pressure decreases."</em></u>

Answer:

D) With an increase in altitude, atmospheric pressure increases as well.

Explanation:

Generally when altitude increases, the value of pressure decreases. This shows that pressure is inversely proportional to altitude. For example, the higher the altitude, the lower the pressure and vice versa. At very high altitude, the number of molecules of air are smaller than the number of moles of air at very low altitude. Thus, the higher the altitude, the lower the atmospheric pressure and the lower the altitude, the higher the atmospheric pressure. Therefore, option (D) is false.

The atomic mass of gallium is 69.72 . The density of iron is 7.87 . The atomic mass of iron is 55.847 . Calculate the number of
laiz [17]

Answer:

the atomic mass of any elemet contains avogardo numberof atoms

In case of Gallium,

69.72 gram is atomic mass and it cotnains around 6.023*10^23 atoms of Gallium

but, 2000 punds = 907184.7 grams

907184.7 gram of gallium contains= 6.023*10^23* 907184/69.72

                                                          = 79 *10^26 atoms

Which of the following trends can be identified on the periodic table?
Jet001 [13]

Answer:

D) atomic radii increase from top to bottom of a group

Explanation:

Atomic radii trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

Other options are incorrect because,

A) atomic radii increase from left to right across the period

Correct = atomic radii decreases from left to right across the period

B) ionization energy increases from top to bottom within a family

Correct =  ionization energy decreases from top to bottom within a family

C) electronegativity decreases from left to right across a period

Correct = electronegativity increases from left to right across a period
