Which of the following is not released by trees into the atmosphere?
a. oxygen
b. water vapor
c. ozone
d. none of the above

Answers

1. Answer is d. all of the above.

Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.

2. Answer is c. ozone.

Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.

1. The correct answer is option D. all of the above.

Global climate change will bring changes in temperature such as heat waves, droughts, volcanic eruption, deforestation, extinction of species due to large shift in temperatures, changes in precipitation such as  heavy snowfall, ocean acidification, and ozone depletion.  

2. The correct answer is option C, ozone.  

Ozone is not released by trees into the atmosphere. Plants have chlorophyll and in the presence of sunlight plants uses sunlight and carbon dioxide to form glucose and oxygen.

6CO₂ + 6H₂O  ->  C₆H₁₂O₆ + 6O₂

During transpiration plants exhale water vapor through the stomata, tiny pores that are found on the surface of the leaves.

Thus trees never release ozone into the atmosphere.

An atom of argon rarely bonds to an atom of another element because an argon atom has(1) 8 valence electrons
(2) 2 electrons in the first shell
(3) 3 electron shells
(4) 22 neutrons

Answers

The answer is (1) 8 valence electrons. Argon, being a noble gas, already possesses a full octet of valence electrons and is, therefore, very, very stable. It has an almost indomitable tendency to retain that octet. That is why it so rarely participates in any sort of bonding.

Find the pH of the following solution. 1.2 L of a solution containing 5.0x10^-4 grams of hydrobromic acid.

Answers

The HBr is a strong acid, that is, it is fully consumed in the reaction

molar mass HBr = 80.91 g/mol

number of moles = 5.0 x 10⁻⁴ / 80.91 = 6.17 x 10⁻⁶ moles

molarity = 6.17 x 10⁻⁶ / 1.2 = 5.14 x 10⁻⁶ M

HBr -------------------  H₃O⁺   +           Br ⁻
↓                                 ↓                     ↓
  5.14 x 10⁻⁶                0                     0
- 5.14 x 10⁻⁶             5.14 x 10⁻⁶   5.14 x 10⁻⁶ 
_____________________________________
0                             5.14 x 10⁻⁶ M         5.14 x 10⁻⁶ M

PH = - log [ H₃O⁺ ]

PH = - log [ 5.14 x 10⁻⁶ ]

PH = 5.82

Why is it important for a scientist studying greenhouse effect to know about mater,forces and energy

Answers

In the 19th century, scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet's temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century, Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea as faulty. In 1938, G.S. Callendar argued that the level of carbon dioxide was climbing and raising global temperature, but most scientists found his arguments implausible. It was almost by chance that a few researchers in the 1950s discovered that global warming truly was possible. In the early 1960s, C.D. Keeling measured the level of carbon dioxide in the atmosphere: it was rising fast. Researchers began to take an interest, struggling to understand how the level of carbon dioxide had changed in the past, and how the level was influenced by chemical and biological forces. They found that the gas plays a crucial role in climate change, so that the rising level could gravely affect our future. (This essay covers only developments relating directly to carbon dioxide, with a separate essay for Other Greenhouse Gases. Theories are discussed in the essay on Simple Models of Climate.)

What is equal to the number of particles in 24 grams of carbon-12? 2 moles 2:1 mole ratio 2:1 molar mass 1:2 molar volume

Answers

Answer:

The answer to your question is 2 moles of Carbon

Explanation:

Carbon-12 means it has a molecular mass of 12g / mol. Mol is defined as the number of grams of an atom in one mol.

To solve this problem, we use proportions

                                    12 g of Carbon ---------------- 1 mol of Carbon

                                     24 g of Carbon --------------   x

                                     

                                      x = ( 24 g x 1 mol ) / 12 g

                                      x = 24 / 12

                                     x = 2 mol of Carbon

Answer:

2 moles
