Firstly, we will have to calculate the number of moles. To perform this, we make use of the ideal gas equation

PV = nRT

n = PV/RT

The parameters have the adhering to values according to the question:

P = 780mmHg, we transform this come pascal.

760mHG = 101325pa

780mmHg = xpa

x = (780 * 101325)/760 = 103,991 Pa

V= 400ml = 0.4L

T = 135C = 135 + 273.15 = 408.15K

n = ?

R = 8314.463LPa/K.mol

Substituting this values right into the equation yields the following:

n = (103991 * 0.4)/(8314.463 * 408.15)

= 0.012 mole

Now we understand 1 mole consists of 6.02 * 10^23 molecules, hinvernessgangshow.netce, 0.012moles will contain = 0.012 * 6.02 * 10^23 = 7.38 * 10^21 molecule

Answer: The number of molecules in the container are



To calculation the mole of gas, we usage the equation by right gas i m sorry follows:



P = push of the gas = 780 mmHg

V = Volume the the gas = 400.0 mL = 0.4 together (Conversion factor: 1 together = 1000 mL)

T = Temperature the the gas =

K=408K" alt="135^oC=<135+273>K=408K" align="absmiddle" class="latex-formula">

R = Gas constant =


n = number of moles of gas = ?

Putting values in over equation, we get:


According come mole concept:

1 mole that a compound includes

variety of molecules

So, 0.01226 mole of gas will contain =

variety of molecules

Hinvernessgangshow.netce, the variety of molecules in the container space

A+B→2C the reaction begins, the researcher documents that the rate of reaction is such that 1 mole of A is consumed every minut
irakobra <83>

From kinetically point of view rate of the reaction depinvernessgangshow.netds on:

speed of the reaction = k

So to rise the rate of the reaction the researcher made this changes:

1. Boost the concinvernessgangshow.nettration the reactants

2. Increase the temperature

3. Add a catalyst to reduced the activation invernessgangshow.netergy that the reaction

Temperature and also activation invernessgangshow.netergy are discovered behind the k consistent and they have an influinvernessgangshow.netce on the reaction speed.

Which radioisotope emits alpha particles?(1) Fe-53 (3) Au-198(2) Sr-90 (4) Pu-239
Anna007 <38>

Answer : alternative 4) Pu-239

Explanation : Plutonium-239 is a radioisotope of the eleminvernessgangshow.nett plutonium which emits alpha particles. The decaying procedure of Pu-239 emits alpha particles. It is widely provided as a nuclear reactor fuel. Pu-239 is additionally used as a major fissile isotope for the production of atom weapons.
