How many moles of atoms are in 5.00 g of 13C

Answers

Answer 1

Answer:

0.384 moles of atoms are in 5.00 g of ¹³C of isotope.

How we calculate moles?

Moles of any substance will be calculate by dividing the given mass of the substance to the molar mass of that substance.

In the question given that:

Given mass of carbon = 5grams (because isotope of carbon is present ¹³C)

Molar mass of carbon = 13g/mol (because isotope of carbon is present ¹³C)

Moles of carbon = 5grams / 13g/mol

Moles = 0.384 moles

Hence, 0.384 moles is the required moles.

Which of the following is an example of a mixture? Option 1: Pure water Option 2: The air in your room Option 3: Gold Option 4: All of the above

Answers

Answer:

Explanation:

Pure water is not a mixture....it is only water

gold ...is only gold

2. air IS a mixture of various gases.....nitrogen , oxygen, co2 etc

Final answer:

Option 2: The air in your room. The air in your room is an example of a mixture because it consists of various gases that can be separated from each other.

Explanation:

The correct answer is Option 2: The air in your room.

A mixture is a combination of two or more substances that are not chemically bonded together. The air in your room is a mixture because it consists of various gases such as oxygen, nitrogen, carbon dioxide, and others. Each gas retains its individual properties and can be separated from the others.

On the other hand, pure water is a compound because it consists of two hydrogen atoms bonded to an oxygen atom, while gold is an element because it is composed of only gold atoms.

What orbits the nucleus of an atom?

Answers

Electrons orbit the nucleus of an atom. They are very small, in fact they are 1/2000 of an amu. Electrons are negative while the inside of an atom includes the positive protons and neutral neutrons. :D

Electrons. They are found in the orbitals outside the nucleus.

Why does the forward reaction slow down over time

Answers

As reactions proceed, they will approach equilibrium, meaning they are completely balanced. As this occurs, there will be fewer products to react. Eventually, after all products are reacted, the reaction will completely stop. Since this doesn't happen instantaneously (usually), the reaction will start quickly and slow as time progresses. hope this helps you hope i am brainliest i need it

The reaction does not stop at equilibrium. Equilibrium is the point at which the rate of the forward reaction equals the rate of the reverse reaction which makes it so that there is no net change (that means that it looks like the reaction has stopped but the forward and reverse reaction is still happening).

The forward reaction slows down over time due to the fact that the concentrations of reactants gets lower over time which makes it so that there are less collisions between reactants per unit of time. Since reactions occur when the reactants collide in the right way, when the number of collisions lowers, the rate of the reaction will also lower. This can be seen through the fact that rate of the forward reaction is rate=k[reactants]. As [reactants] gets lower, the rate of the forward reaction will get lower as well. (rate=k[reactants] is the rate law for the forward reaction with [reactants] being the concentration of reactants and k being the rate constant).

I hope this helps. Let me know if anything is unclear.
