During one part of the water cycle, heat from the Sun causes liquid water to change into water vapor, which rises into the atmos

phere.
Which statement best describes the reverse of this process?
As liquid water falls from the atmosphere to land, it turns into a gas
As the Sun's rays warm solid ico, it begins to melt into liquid water.
As liquid water from streams and groundwater drains into large bodies of liquid water, it turns to gas.
As water vapor meets cooler air, it changes into droplets of liquid water that return to Earth's surface,

A

Explanation:

Evaporation is a key step in the water cycle. Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor

2. What would be the outcome of a unicellular organism that cannot maintain homeostasis? (1 point)
Juli2301 [7.4K]

Answer:

Option A = it dies

Explanation:

Homeostasis:

It is the ability of organisms to maintain the equilibrium in its internal environment in order to deal with external environmental changes.

If the unicellular organism cannot maintain the homeostasis it would die.

Importance of homeostasis:

It is constant chemical and physical condition of cell. The unicellular organisms in maintained homeostasis condition can grow and reproduce. They respond to the environment and transfer energy. It is the primary objective of unicellular organism other wise they would not survive.

It is very important for them because they totally rely on it and can perform the necessary functions of life.

While in case of multi cellular organisms all cells communicate with each other to maintain the homeostasis.

Many organisms in Kingdom Fungi grow best in warm, moist conditions.
almond37 [142]

Answer:

Kingdom Fungi refers to the group of eukaryotic organisms like fungi, mushrooms, molds and yeasts.

Explanation:

The fungi kingdom is made up of eukaryotic organisms whose cell walls are made of chitin.

Next I will name <u>some characteristics</u> of these organisms:

  • They are not plants or animals .
  • They are responsible for absorbing nutrients from other organisms, which they use as food .
  • Some, like mushrooms and yeast, are edible.
  • They present cellular orguils and vacuoles .
  • They lack chloroplasts .
  • They produce spores .
  • They are able to break down dead matter .
  • They develop in humid and dark areas .
  • Penicillin is obtained from these organisms.

How many kg of solvent would contain 130 grams of ZnBr2 if the solution was 0.950 grams
Semenov [28]

Answer:

0.00731 kg

Explanation:

Given that solution is a product of solute and solvent.

Hence, solution = solute * solvent

In this case, the solution is given as 0.950 grams = 0.00095 kilograms

solute is given as 130 grams = 0.13 kilograms

Hence to get the amount of solvent in kilograms, we have

Solution ÷ Solute => 0.00095 ÷ 0.13

= 0.0073076923

=> 0.00731 kilograms

Can we move only one electron from its orbit to another orbit of lower energy without moving other electrons of the atom? well i
Mrac [35]
Yes, it can happen.

If all the lower energy orbits are already filled with electrons, then it cannot happen since the lower orbitals will already be full, hence another electron will have to move.

However, if the lower energy orbits are not full (for instance if one excited electron goes back to its normal state), then it can happen.

Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 63. g of octane is mi
Sever21 [200]

Answer:

52.1 g is the maximum mass of CO₂, that can be produced by this combustion

Explanation:

Mass of Octane: 63 g

Mass of O₂: 59.4 g

This is a combustion reaction where the products, are always water and CO₂. We define the equation:

2C₈H₁₈ (l)  +  25O₂(g)  →  16CO₂(g)  +  18H₂O(g)

As we have, both mases of each reactant, we must define which is the limiting reagent. We convert the mass to moles:

63 g. 1mol / 114g = 0.552 moles

59.4 g . 1mol / 32g = 1.85 moles

Certainly, the limiting reagent is the oxygen:

2 moles of octane need 25 moles of O₂ to react

Therefore, 0.552 moles of octane must need (0.552 . 25) /2 = 6.9 moles of O₂ (I do not have enough moles of oxygen, I need 6.9 and I only got 1.85 moles)

When we know the limiting reagent we can do the calculations with the stoichiometry of the reaction:

25 moles of O₂ can produce 16 moles of CO₂

Therefore, 1.85 moles of O₂ may produce (1.85 . 16) /25 = 1.18 moles.

We convert the moles to mass to get the final answer:

1.18 mol . 44 g / 1mol = 52.1 g
