A. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

B. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

C. Particle emitted = beta particles; protons gained = 1; Change in mass = 0

D. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0

F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

Explanation:

Radioactivity is the spontaneous disintegration of nucleus of an atom resulting in emission of particles and radiation unyil a stable atomic nuclei is obtained. Substances that are exhibit radioactivity are known as radioactive substances and are usually isotopes of stable atoms.

The types of radiation emitted by a radioactive substances include alpha rays, beta rays, and gamma rays.

Alpha rays or particles are fast moving positively charged particles with a mass number of four and atomic number of two. Thus, each alpha particle is a helium nucleus.

Beta rays or particles are vary fast moving stream of electrons having a mass number of zero and a charge of -1.

Gamma rays are not particles but are electromagnetic waves similar to visible light and X-rays but with shorter wavelengths. They have no mass or charge.

An atom emitting alpha particles has its mass reducing by 4 units and its atomic number decreasing by 2.

An atom emitting beta particles as it decays has no change in mass but its atomic number increases by 1.

From the table:

A. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

B. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

C. Particle emitted = beta particles; protons gained = 1; Change in mass = 0

D. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0

F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
