Is the force between protons in the nucleus attractive or repulsive

Chemistry
1 answer:
Alex73 [517]2 years ago
5 0

Answer:

Inside the nucleus, the attractive strong nuclear force between protons outweighs the repulsive electromagnetic force and keeps the nucleus stable. Outside the nucleus, the electromagnetic force is stronger and protons repel each other.

When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope. What is the order of
zloy xaker [14]

Answer:

Second order

Explanation:

Given that:

When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.

From the integration method for the second order of reaction.

Suppose that:

rate = k₂[A]²

∴

\dfrac{1}{A}=\dfrac{1}{A_0}+k_2t

Therefore, a plot of the linear function \dfrac{1}{A} versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be \dfrac{1}{A_o}

The linear plot for a second order reaction can be seen in theimage attached below.

Air is about 78.0% nitrogen molecules and 21.0% oxygen molecules. Several other gases make up the remaining 1% of air molecules.
kherson [118]

Answer:

The partial pressure of the other gases is 0.009 atm

Explanation:

Step 1: Data given

Air is about 78.0% nitrogen molecules and 21.0% oxygen molecules and 1% of other gases.

The atmospheric pressure = 0.90 atm

Step 2: Calculate mol fraction

If wehave  100  moles of air, 78 moles will be nitrogen,

21  moles will be  oxygen, and  1  mol will be other gases.

Mol fraction = 1/100 = 0.01

Step 3: Calculate the partial pressure of the other gases

Pgas = Xgas * Ptotal

⇒ Pgas = the partial pressure = ?

⇒ Xgas = the mol fraction of the gas = 0.01

⇒Ptotal = the total pressure of the pressure = 0.90 atm

Pgas = 0.01 * 0.90 atm

Pgas = 0.009 atm

The partial pressure of the other gases is 0.009 atm
