Answer:

a. Law of Constant Composition, Law of Multiple Proportions, Law of Conservation of Mass Alpha particles are scattered at a variety of angles (over 90 degrees) when bombarded at gold foil.

Explanation:

Which of the following supports the claim that the atom is like a solid positive cookie with negative electrons embedded within it? (This model is known as the Plum Pudding Model of the atom, and is illustrated to the right).

a. Law of Constant Composition, Law of Multiple Proportions, Law of Conservation of Mass Alpha particles are scattered at a variety of angles (over 90 degrees) when bombarded at gold foil.

b. When light from hydrogen emissions passes through a diffracting grating, there are distinct bands of color.

c. The Cathode Ray Tube experiment, in which the ray was attracted to the south pole of the magnet.

the plumbudding model of the atom was postulated by  JJ Thompson and plum pudding model. . ... Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.

so a. correctly typifies the thompson model of the atom

A radioactive decay is illustrated. Which radioactive emission is a product of this decay?
hram777 [196]

The radioactive decay is shown in the image attached to this answer

Answer:

Alpha

Explanation:

An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.

If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.

A student was given a sample of crude acetanilide to recrystallize. The initial mass of the the crude acetanilide was 166 mg. Th
padilas [110]

Answer:

The percentage of mass recover from recrystallization = 24.69 %

Explanation:

Given that

Initial mass of crude acetanilide = 166 gm

The mass after recrystallization = 125 gm

The mass recover from recrystallization= 166 - 125 gm

The mass recover from recrystallization= 41 gm

The percentage of mass recover from recrystallization can be find as

percentage\ of\ mass\ recover\ from\ recrystallization\ =\dfrac{166-125}{166}

The percentage of mass recover from recrystallization = 24.69 %

An object is hung from a spring balance attached to the ceiling of an elevator cab. The balance reads 85 N when the elevator is
Ilia_Sergeevich [38]

Answer:

Explanation:

Balance force ( W ) = 85 N

a)  moving upward with constant velocity (V ) = 7.9 m/s.

The reading will not change since it is moving with constant velocity

  W = 85 N

b) Moving upward with V = 7.9 m/s and decelerating at the rate of (a ) = 1.1 m /s²

The net force ( F ) = W - ma

where m = W/g = 85/9.81 = 8.6646 kg

F = 85 - 8.6646 * 1.1 = 75.4689 N
