Light Pollution affects both indirectly by inter fearing with and destroying the life cycles of the pollinators or other animals that interact with them.

A 1.2 L weather balloon on the ground has a temperature of 25°C and is at atmospheric pressure (1.0 atm). When it rises to an el

icang [17]

Answer:

The temperature of the air at this given elevation will be 53.32425°C

Explanation:

We can calculate the final temperature through the combined gas law. Therefore we will need to know 1 ) The initial volume, 2 ) The initial temperature, 3 ) Initial Pressure, 4 ) Final Volume, 5 ) Final Pressure.

Initial Volume = 1.2 L ; Initial Temperature = 25°C = 298.15 K ; Initial pressure = 1.0 atm ; Final Volume = 1.8 L ; Final pressure = 0.73 atm

We have all the information we need. Now let us substitute into the following formula, and solve for the final temperature ( T $_2$ ),

P $_1$ V $_1$ / T $_1$ = P $_2$ V $_2$ / T $_2$ ,

T $_2$ = P $_2$ V $_2$ T $_1$ / P $_1$ V $_1$ ,

T $_2$ = 0.73 atm $*$ 1.8 L $*$ 298.15 K / 1 atm $*$ 1.2 L = ( 0.73 $*$ 1.8 $*$ 298.15 / 1 $*$ 1.2 ) K = 326.47425 K,

T $_2$ = 326.47425 K = 53.32425 C

Based on the information in the weather map, which direction will the wind move? A) east to west B) west to east C) north to sou

Fofino [41]

Hello. You forgot to replace the map needed to answer that question. The map is attached below:

Answer:

B) west to east

Explanation:

The letter H on the map represents an area with high air pressure, while the letter L represents an area with low air pressure. As in the areas of lower temperature or colder the pressure is greater, the wind leaves these areas and goes towards those of higher temperature, which present less pressure. For this reason, we can say that the wind is moving from west to east.

The greater the pressure difference between the regions, the greater the wind speed, and in these situations, strong winds or winds can occur, which are given different names, depending on the location: hurricane (Caribbean), tornado (USA), typhoon (Asia).

Which of the following molecules or ions is polar? (20 POINTS)

taurus [48]

For NO3- molecule(fig.1)

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NO3 are polar.

2. In the geometry of the molecule bond polarities cancel out each other (since it is a vector) so NO3- ion molecule is non polar

3. Nitrate (NO3-)ion geometry would be trigonal planar

For CCl4 molecule(fig.2)

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in CCl4 are polar.

2. It is a completely symmetrical molecule.

3.Carbon is the centre of CCl4 have four covalent bonds and it has no lone pairs. They are all equidistant the C-Cl bond polarities cancel out. So CCl4 molecule is non polar

For NH3 molecule(fig.3)

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NH3 molecule are polar.

2. it has a pyramidal structure.

3. the individual N-H bond dipoles don't cancel out. This dipole moment for the molecule indicates that NH3 is a polar molecule

For SF6 molecule(fig.4)

1.F is more electronegative than S. So the bonds are polar.

2. The symmetry of the molecule is symmetrical so that the dipole moments of bonds cancel correspond so the molecule is non-polar.

3. it has octahedral structure
