Answer all questions pls
tekilochka [14]

Answer:

1) The cryosphere contains the frozen parts of the planet. This sphere helps maintain Earth's climate by reflecting incoming solar radiation back into space. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting.

2) Organisms like the Frilled Shark, Giant Spider Crab. Atlantic Wolffish Pair, Fangtooth Fish, Six-Gill Shark, Giant Tube Worms, Vampire Squid, Pacific Viperfish. But there are most likely archaeabacteria which are prokaryotic bacteria or single-celled organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.

3) Many different types of plant and animal communities call estuaries home because their waters are typically brackish — a mixture of fresh water draining from the land and salty seawater. This unique combination of salty and fresh water creates a variety of habitats. Estuaries are full of decaying plants and animals. This makes the soil of estuaries rich in nutrients. Because the soil is so rich, lots of different plants grow in estuaries. The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary.

4) Temperature, humidity, precipitation, air pressure, wind speed, and wind direction are key observations of the atmosphere that help forecasters predict the weather. These same factors have been used since the first weather observations were recorded. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists. The three main factors of weather are light (solar radiation), water (moisture) and temperature.

Explain why the atomic number is called the fingerprint of element
Dovator [93]

Answer:

No element shares the same atomic number. The atomic number of every element is unique to itself, just like a fingerprint is unique to a human. The atomic number of element allows us to identify it, like how we can identify a person from their fingerprint.

The following thermochemical equation is for the reaction of Fe 3 O 4 (s) with hydrogen (g) to form iron and water vapor Fe 3 O
Mila [183]

Answer:

41.3kJ of heat is absorbed

Explanation:

Based in the reaction:

Fe₃O₄(s) + 4H₂(g) → 3Fe(s) + 4H₂O(g) ΔH = 151kJ

<em>1 mole of Fe3O4 reacts with 4 moles of H₂, 151kJ are absorbed.</em>

63.4g of Fe₃O₄ (Molar mass: 231.533g/mol) are:

63.4g Fe₃O₄ × (1mol / 231.533g) = <em>0.274moles of Fe₃O₄</em>

These are the moles of Fe₃O₄ that react. As 1 mole of Fe₃O₄ in reaction absorb 151kJ, 0.274moles absorb:

0.274moles of Fe₃O₄ × (151kJ / 1 mole Fe₃O₄) =

<h3>41.3kJ of heat is absorbed</h3>
