NISA [10]3 years ago
7 0

Answer:

Alpha particles, Beta particles and Gamma rays

Explanation:

The emission of particles when a radioactive atom decays is called radioactivity.

An atom is radioactive as a result of unstable nucleus. This unstable nucleus of the atom disinintegrates and leads to emission of Alpha particles, Beta particles and gamma rays.

Alpha particles contain 2 protons and 2 neutrons. They are positively charged

Beta particles are negatively charged

Gamma rays are electromagnetic waves with short wavelength

Calculate Ho298 for the process
Inga [223]

Explanation:

As per the Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

Hence, according to this law the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

Sb + \frac{3}{2}Cl_2 \rightarrow SbCl_{3}    \Delta H^0_1 =  -314 kJ  ..........(1)

SbCl_{3} + Cl_2 \rightarrow SbCl_{5}    \Delta H^0_2 = -80kJ   ..............(2)

The final reaction is as follows:  

Sb + \frac{5}{2}Cl_{2} \rightarrow SbCl_{5}  \Delta H^0_3 = ?  .............(3)

Therefore, adding (1) and (2) we get the final equation (3) and value of \Delta H^{0}_{3} at 298 K will be as follows.

             \Delta H^{0}_{3} = \Delta H^{0}_{1} + \Delta H^{0}_{2}    

                       = -314 kJ + (-80) kJ

                       = -394 kJ

Thus, we can conclude that H^{o} at 298 K for the given process is -394 kJ.

Which describes Ernest Rutherford’s experiment?
inna [77]

The best description of Ernest Rutherford's experiment is letter C. The positively charged particles were fired through a gold foil. Most of these particles went right through, while others bounced back. This experiment led to the discovery of the nucleus.

Which of the following can an isosceles triangle not be? an acute triangle a scalene triangle an equilateral triangle a right tr
zimovet [89]

Answer;

A scalene

Explanation;

A triangle is a geometric figure with three sides and three angles that always add up to 180 degrees.

Based on properties triangles can be classified as equilateral, scalene, isosceles and right triangles.

Equilateral triangles has all the three sides and the angles equal, an isosceles triangle has two of its sides equal, and two angles that are known as the base angles equal. A scalene triangle has all the three angles and sides different from each other. A right triangle is a triangle in which one of the angle is right angle or is 90 degrees.

An isosceles triangle may be a right triangle, equilateral triangle, and also may be an acute triangle, however an isosceles triangle can never be a scalene triangle
