<span>O2 travels slower than H2, Ne, N2, and CO. This is due to the fact that O2 has a heavier molecular weight than the others. O2 has a weight of 32 grams per mole. N2 and CO are the next highest with 28 grams per mole. Ne is 20 grams per mole, and H2 is 2 grams per mole.</span>

Answer:

O2

Explanation:

The distribution of the speed of gas particles is represented via a Maxwell-Boltzmann graph which is essentially a plot of the velocity of gas particles vs the fraction of gas particles.

A proper assessment of the velocity can be made by measuring the root mean square velocity of the particles which is given as:

v_{rms} =\sqrt{\frac{3RT}{M} } ----(1)

where, R = gas constant = 8.314 J/mol-K

T = temperature of gas in K

M = molecular weight of the gas

Based on equation (1), the velocity of the gas particle is inversely proportional to its molecular weight.

The molecular/atomic weights of the given gases are:

Ne = 20 g/mol

H2 = 2 g/mol

CO = 28 g/mol

N2 = 28 g/mol

O2 = 32 g/mol

Since O2 has the highest molecular weight, it will travel the slowest.

What would diluting the vinegar do to the rate of a reaction between vinegar and sodium hydroxide? decrease the rate of reaction
GarryVolchara [31]
Vinegar is aceti acid diluted in water.

The reaction of vinegar with sodium hydroxide is:

CH3COOH + NaOH ---> CH3COONa + H2O

That is an acid-base reaction.

The speed of reaction is proportional to the concentrations of the reactants.

Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.

Answer: decrease the rate of reaction.

Why does the earth rotate
boyakko [2]

Answer:

A

Explanation:

Your answer would be A because Earth is formed from cold gases collapsing due to gravity. The Solar System was formed when a huge amount of dust and gas began to collapse under its own gravity, and as the cloud collapse it started to spin causing the material within the cloud to gather into a swirl and then formed into planets and as the planets are formed they kept this spinning motion.

Explain the difference between a physical property and chemical property. Give examples of each.
MA_775_DIABLO [31]
A physical property is what a substance is like; it's directly observable. On the other hand, a chemical property is how a substance behaves; its reactivity.

Examples of a physical property are: color, texture, boiling point, freezing point, and melting point.

Examples of a chemical property are: flammability, combustion, and formation of a precipitate.

Compare the sizes and directions of the arrows in each picture representing forces acting on the person. Which of the following
expeople1 [14]

Answer:

A, is a girl balancing on her hands, a red arrow is pointing up and is the same length as an arrow pointing down.

Explanation:

vvEven she was still on her feet the force thats pulling her down is gravity and when you have figure the force that makes it easier so when the 2 arrows are the same size that means the force is balenced
