The atoms and molecules in a gas are in constant motion. Temperature is a measure of this motion. How are these related? As temp

erature increases, the molecules and atoms move faster. As temperature decreases, the molecules and atoms move farther apart. As temperature increases, the atoms and molecules move closer together. As temperature decreases, the molecules and atoms move faster.

Here we have to choose the correct statement on the effect of temperature on the motion of the molecules and atoms of a gas.

As the temperature increases the molecules and atoms move faster.

As per the kinetic theory of gas molecules and atoms the kinetic energy (K.E.) of the atom or molecules is related to temperature by the equation

K.E. = \frac{3}{2}kT ( k = Boltzmann constant, T = temperature.

Thus as the temperature increases the K.E. increases thus the atom or molecules move faster.

With the decrease of temperature the movement of the atoms or molecules will be less and they will be near to each other.

The increment of temperature increase the K.E. thus the atoms or molecules move apart from each other.

With the decrease of temperature the movement of the atoms or molecules decreases.

You wish to construct a buffer of pH=7.0. Which of the following weak acids (w/ corresponding conjugate base) would you select?
Alex17521 [72]

Answer:

C.) HOCl Ka=3.5x10^-8

Explanation:

In order to a construct a buffer of pH= 7.0 we need to find the pKa values of all the acids given below

we Know that

pKa= -log(Ka)

therefore

A) pKa of  HClO2 = -log(1.2 x 10^-2)

=1.9208

B) similarly PKa of HF= -log(7.2 x 1 0^-4)= 2.7644

C)  pKa of HOCl= -log(3.5 x 1 0^-8)= 7.45

D) pKa of HCN = -log(4 x 1 0^-10)=  9.3979

If we consider the  Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution

The weak acid for making the buffer must have a pKa value near to the desired pH of the weak acid.

So, near to value, pH=7.0. , the only option is HOCl whose pKa value is 7.45.

Hence, HOCl will be chosen for buffer construction.

Masja [62]

Answer:

  The purpose of this guide is to help you write a clear and concise report that summarizes the lab I just completed.  This lab showed me how water carries rocks to a new location. For instance how the first model showed how a stream would act with light drizzle to downpour as I saw the outcomes were all if not completely then partially different  

            I read the information that was given to me before I started each lab lesson and went on from there.

How many moles are in 2.8x10^23 atoms of Calcium?
Zielflug [23.3K]

Answer: 1 mole ➡️ 6.022×10²³ atoms of si.

X mole ➡️ 2.8×10²⁴ atoms of si.

X = 2.8×10×10²³/6.022×10²³

= 28/6.022

= 4.65 moles.
