The diagram below shows some subatomic particles. A diagram similar to a flowchart starts with a circle labeled Atom. From there

, a line leads to a small circle labeled Electron and a larger one labeled Nucleus. From nucleus, two lines lead to a group of circles, labeled Neutrons and protons. From there, two lines lead to a circle surrounding two blue and one orange smaller circles. One of the blue circles is labeled with a question mark. What is the particle that is labeled with a question mark (?) in the diagram?

If the pressure on an ideal gas is increased, what will happen to the volume of the gas?
kumpel [21]
If the pressure on an ideal gas is increased, the volume of the gas will decrease. This can be predicted with the use of the ideal gas equation which is expressed as: PV = nRT. At constant temperature, we can say that pressure and volume are inversely related. Thus, as one value increase, the other decrease.

a 20 liter sample of gas is kept under a constant pressure of 100 kpa. the temperature is lowered from 360 k to 90 k. what is th
Setler79 [48]

To solve this we assume that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 =90 x 20 / 360

<span>V2 = 5 L</span>

The nucleoside adenosine exists in a protonated form with a pKa of 3.8. The percentage of the protonated form at pH 4.8 is close
Natasha_Volkova [10]

Answer:

Ok:

Explanation:

So, you can use the Henderson-Hasselbalch equation for this:

pH = pKa + log(A^-/HA) where A- is the conjugate base of the acid. In other words, A- is the deprotonated form and HA is the protonated.

We can solve that

1 = log(A^-/HA\\) and so 10 = A^-/HA or 10HA = A-.  For every 1 protonated form of adenosine (HA), there are 10 A-. So, the percent in the protonated form will be 1(1+10) or 1/11 which is close to 9 percent.

Zinc metal reacts with hydrochloric acid (HCl) to produce hydrogen gas. What best describes this reaction?
Lena [83]

Answer: What best describes the reaction is "A single replacement reaction takes place because zinc is more reactive than hydrogen."
