What periodic trends exist for electronegativity?
Anna007 [38]
The highest electronegativity is in the elements in the top left corner of the periodic table, and the lowest in the bottom right corner. Therefore, traveling up or to the left across the periodic table will increase the electronegativity

A chemist measures the energy change ?H during the following reaction:
slamgirl [31]

Answer:

Endothermic

It absorbs heat

1.20 × 10³ kJ

Explanation:

Let's consider the following thermochemical equation.

2 H₂O(l) → 2 H₂(g) + O₂(g)    ΔH = 572 kJ

Since ΔH > 0, the reaction is endothermic, that is, it absorbs heat when H₂O reacts.

572 kJ are absorbed when 36.03 g of water react. The heat absorbed when 75.8 g of H₂O react is:

75.8 g H₂O × (572 kJ/36.03 g H₂O) = 1.20 × 10³ kJ

Match each statement with a layer of the atmosphere. There will be two statements for each layer.
LuckyWell [14K]

<u>The troposphere: </u>

H. This layer can have thunderstorms or clear, sunny skies.

A. The biosphere interacts most with this layer. 

<u>The stratosphere:</u>

B. It is the second layer from Earth's surface. 

G. Winds are strong and steady in this layer. 

<u>The mesosphere:</u>

E. It is heated by the ozone layer beneath it. 

D. This layer is where most meteor showers occur. 

<u>The thermosphere :</u>

F. It contains the ionosphere and exosphere. 

C. It contains layers of single, unmixed gas. 

<u>Explanation:</u>

Depending on the Earth's  temperature the atmosphere can be separated into layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are those layers. The lowest layer is named as Troposphere (0-10 km from the Earth outer surface), it comprises about 75% of the atmosphere's total air and nearly most the water vapor.

Stratosphere (10-30) includes much of the surface ozone. The change in height temperature arises as this ozone absorbs ultraviolet (UV) radiation from the sun. The temperature in Mesosphere (30-50 Km) declines again with height, hitting a minimum of about -90 ° C at the "mesopause." Above this thermosphere (50-400 Km) is settled which is a area where temperatures rise with height once again. The penetration of intense  UV and X-ray radiation from the sun induces this temperature rise.

How does water help us live
SSSSS [86.1K]

Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to re-hydrate by drinking fluids and eating foods that contain water.
