Which nuclear emission has no charge and no mass?(1) alpha particle (3) gamma ray
(2) beta particle (4) positron
Answers
Answer: Gamma ray
Explanation: Nuclear Emission explains the release of energy stored in the nucleus of an atom in the form of particles like alpha particles, beta particles, gamma ray etc.
Alpha particles are the helium atom having +2 charge.
Beta particles have -1 charge thus beta particle and the electron are same.
Positron has a charge of +1 electron having 1/2 spin.
Gamma rays are the rays which are neutral and have no mass.
Final answer:
A gamma ray is a nuclear emission that has no charge and no mass.
Explanation:
Nuclear radiation refers to the emission of particles or electromagnetic waves from atomic nuclei undergoing decay. Types include alpha, beta, and gamma radiation, each with varying properties and effects. It is a fundamental concept in nuclear physics and has applications in medicine, energy production, and weaponry.
The nuclear emission that has no charge and no mass is the gamma ray. Unlike the other options listed, which are particles, gamma rays are electromagnetic radiation and do not have mass or charge. They are highly penetrating and can pass through many materials without being deflected.

510.17 cm³ is the volume of Iron has a density of 7.86 g/cm3 (1 cm3=1 mL) and has a mass of 4.01 kg.
What is density?
Density is the amount of mass of a substance present per volume of the cubic centimeter and it is the ratio of the mass of a substance to the volume of the substance with a unit centimeter cube.
The Iron has a density of 7.86 g/cm³ and mass of 4.01 kg so,
mass in gram = 4.10 / 1000 = 0.041
Density = mass/volume
Substituting the value in the equation,
volume = 0.041 /7.86 g/cm³
volume = 510.17 cm³
Therefore, the volume of Iron has a density of 7.86 g/cm3 (1 cm3=1 mL) and has a mass of 4.01 kg is 510.17 cm³.

4.01 x 1000 = 4010 g
Density = mass / volume
7.86 = 4010 / volume
Volume = 4010 / 7.86
Volume = 510.17 cm³

Answer: Option (d) is the correct answer.
Explanation:
Bases are the electron rich species which readily accept a proton. Therefore, when ammonia is classified as a base in a chemical reaction with an acid, it readily accepts a proton to give ammonium cation.
For example, the reaction of ammonia with hydrochloric acid will be as follows.
Thus, we can conclude that ammonia, , will accept a proton and become
.

Answer:
Two
Step-by-step explanation:
There are two ways to determine the number sets of equivalent protons in a compound.
(a) By substitution
Replace each H with a different group and see if you get a different compound
For example, the six CH₃ H atoms are an equivalent set, because, if I replace any one of them, I will always get the same compound: 1-chloromethyl-4-methylbenzene (Fig. 1).
Similarly, the four aromatic H atoms are an equivalent set. If I replace any one of them, I will always get the same compound: 2-chloro-1,4-dimethylbenzene (Fig. 2).
Thus, there are two sets of equivalent protons in p-xylene.
(b) By symmetry
Two atoms are equivalent if one can be converted into the other by a symmetry operation on the molecule.
The methyl hydrogens can be interconverted by a combination of reflections about the AB and CD mirror planes and byrotations about the C-C bonds to the ring (Fig. 3).
Similarly, the four aromatic H atoms can be interconverted by a combination of reflections about the AB and CD mirror planes.
Again, we find two sets of equivalent protons.

Answer:
percent by mass = 79%
Explanation:
Data Given:
mass of solute (Na₂CO₃) = 75 g
mass of solvent ( water ) = 20 g
mass percent of solution = ?
Solution:
Formula used to find percent by mass
mass of solute / mass of solution x 100 . . . . . . (1)
first we have to find mass of solution
mass of solution = mass of solute + mass of Solvent . . . . (2)
put values in equation 2
mass of solution = 75 g + 20 g
mass of solution = 95 g
Now,
put values in equation 1
Percent by mass = mass of solute / mass of solution x 100
Percent by mass = 75 g / 95 g x 100
Percent by mass = 79 %
so,
The percent of the solution by mass = 79%
***Note:
The same work can be used for the other values too i.e. if you have 20 g of solute and 75 g solvent.
