Which of the following contains most of the water on earth? A)the oceans
C)the atmosphere
D)ice and aquifers


Answer 1

The oceans contain most of the water on earth. Therefore, option A is correct.

Which ocean contains the most water?

The largest and deepest ocean basin in the world is the Pacific Ocean. The Pacific Ocean basin is by far the largest in the world, covering around 63 million square miles and holding more than half of the planet's free water.

About 97 percent of the water on Earth is in the ocean; the other 3 percent is in glaciers and ice, underground in rivers and lakes. Approximately 97 percent of the 332 million cubic miles of water that make up the world's entire water supply are located in the ocean.

More than 70% of the surface of our globe is covered by the water. It's difficult to believe, yet our oceans contain nearly 97 percent of the water on Earth.

Thus, option A is correct.

Calculate the rms speed of an oxygen gas molecule, o2, at 29.0 ∘c . express your answer numerically in meters per second.


The rms speed of a gas can be calculated using the following rule:
Vrms = sqrt ( 3RT / M) where:
R is the gas constant = 8.314
T is the temperature = 29 + 273 = 302 degrees kelvin
M is the molar mass of the gas (oxygen) = 2*16 = 32 grams = 0.032 kg

Substitute in the equation to get Vrms as follows:
Vrms = sqrt [(3*8.314*302) / (0.032)] = 485.05 meters/sec

The rms speed of an oxygen gas molecule : 485.17 m/s

Further explanation

Kinetic Molecular Theory (KMT) states that a gas consists of molecules that move at a constant and random speed. The collisions between molecules are perfectly elastic so that no energy is wasted.

The molecules move in straight lines until they collide

Energy because this motion is expressed as Kinetic energy (KE) which can be formulated as:


The average kinetic energy value is only affected by temperature changes. The higher the temperature, the average kinetic energy of the molecule increases

This molecule is very small when compared to the distance between molecules, so the volume of gas contains mostly empty space

Gas particles move randomly (both speed and direction , as vector)

Average velocities of gases can be expressed as root-mean-square averages. (V rms)

R = gas constant, T = temperature, Mm = molar mass of the gas particles

From the question

R= 8.314 J/mol K

T = 29 + 273 = 302 K

Mm = molar mass O₂ = 2.16 = 32 g/mol = 32.10-3 kg/mol

How many phosphate bonds are responsible for the high energy content of ATP? A) one B) two C) three D) four


The answer is A. The ATP is called adenosine triphosphate which means that it has three phosphate groups. But when energy is released from ATP, ATP will transform to ADP. In this process, only one phosphate bond will break.

2. Choose the 2 atoms that are isotopes. Think about what isotopes have in common and what they have that differs. * 1 point
