Which two elements have properties that are the most similar?
elena-14-01-66 [18.8K]

Answer:

The answer to your question is letter b) He and Ne

Explanation:

Elements that have similar properties are placed in the same group in the periodic table.

So

A C and F  These elements do not have similar properties because C is in group 4A and F is in group 7A. This is not the right answer.

B He and Ne  These elements have similar properties becase they are in the same group (8A).

C Al and Si  These elements do not have similar properties because Al is in group 3A and Si is in group 4A. This is not the right answer.

D N and S These elements do not have similar properties because N is in group 5A and S is in group 6A. This is not the right answer.

Hydrogen and chlorine gases react to form HCl. You and a friend are on opposite sides of a long hallway, you with H2 and your fr
natali 33 [55]

Answer: It is true that Your friend should release the Cl_{2} first.

Explanation:

The velocity of particles of a gas is inversely proportional to the mass of gas. This means that more is the mass of gas less will be its velocity.

Or, more will be the mass of gas more slowly it will move from one place to another.

The molar mass of chlorine gas is more than the molar mass of hydrogen gas. Therefore, chlorine gas will move slowly.

So, your friend should release the Cl_{2} gas first and then according to the length of room you should release the H_{2} gas.

Thus, we can conclude that it is true that Your friend should release the Cl_{2} first.

Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider a mixture of six nitrogen molecules and six hydrogen molec
Nezavi [6.7K]

Answer:

a)  No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.

Explanation:

The balanced reaction between nitrogen and hydrogen molecules to give ammonia molecules is:

N_{2}(g)+3H_{2}(g) -->2NH_{3}

Thus one molecule of nitrogen will react with three molecules of hydrogen to give two molecules of ammonia.

We have six molecules of each nitrogen and hydrogen in the closed container and they undergo complete reaction it means the limiting reagent is hydrogen. For six molecules of nitrogen, eighteen molecules of hydrogen will be required.

So six molecules of hydrogen will react with two molecules of nitrogen to give four molecules of ammonia.

The product mixture will have

a) No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.
