trench
abyssal plain
mid-ocean ridge

Answers

Answer 1
Answer:

The feature that is been formed as a result of a tectonic plate boundary which brings about underwater mountain range in the open ocean is mid-ocean ridge.

What is mid-ocean ridge ?

The mid-ocean ridge  is a continuous range of undersea volcanic mountains which is an enclosure of the globe.  It is usually formed and evolves due to spreading in Earth's lithosphere.

These models show the electron structures of two different nonmetal elements.Which element is likely more reactive, and why?A.) Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.B.) Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.C.) Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.D.) Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

If you have a 92.0 gram sample of water, then what mass of hydrogen and what mass of oxygen are in the sample? Make sure you answer in “grams” of Hydrogen and “grams” of Oxygen.

Answers

Answer:

\boxed{\text{10.29 g H and 81.71 g O}}

Explanation:

The formula of water is H₂O.

1. Calculate the molar mass of water

2 H = 2 × 1.008 =   2.016 u

1 O = 1 × 16.00  = 16.00   u

                  MM = 18.02    u

2. Mass of hydrogen

\text{Mass of H} = \text{92.0 g water} \times \dfrac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g\text{Mass of H} = \text{92.0 g water} * \frac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g H} H}

3. Mass of 0xygen

\text{Mass of O} = \text{92.0 g water} * \frac{\text{16.00 g H}}{\text{18.02 g water }} = \textbf{81.71 g O}\n\n\text{The masses are } \boxed{\textbf{10.29 g H and 81.71 g O}}

Final answer:

A 92 gram sample of water will consist of approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.

Explanation:

Water

consists of two hydrogen atoms and one oxygen atom. Therefore, it has a

molecular formula of H2O

. To find the mass of each element in a 92 gram sample, we need to know the molar mass of the elements and the compound. The molar mass of hydrogen (H) is about 1 gram per mole, and oxygen (O) has a molar mass of 16 grams per mole. So, the molar mass of water (H2O) is approximately 18 grams per mole (2*1 + 16). This means that in one mole of water, 2 grams are hydrogen and 16 grams are oxygen. If we scale this up to 92 grams, we find that there are approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.

What are two actions that would cause an increase in relative humidity

Answers

relative humidity increases when the amount of moisture air can hold increases.The increase can be caused by the introduction of more moist air OR a temperature drop of the air/moisture mixture without a loss of moisture. Colder air will hold less moisture than warm air;as the temperature goes down the amount of moisture relative to what the air can hold increases

Answer:

cooler air

Which correctly describes molecule "a" in this diagram

Answers

Answer is: adenosine triphosphate.

ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).

ATP is short for adenosine triphosphate

Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.  

The correct answer is A- Adenosine Triphosphate
