Answer: Option (c) is the correct answer.
Explanation:
A positron is denoted as 
, a neutron is denoted as 
, an electron is denoted as 
, and a proton is denoted as 
.
Therefore, when 
will decay into 
this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.
The reaction will be as follows.
Sp2 hybridization forms 1 sigma bond and 1 pi bond.
Answer: Magnets have a force which is known as no contact force. This force tries to attract the metallic objects near it, which makes it move.
Explanation:
The volume occupied by 2.00 moles of nitrogen gas at the same temperature and pressure will be
0.500 moles = 11.2 Liters
what about 2 moles =? liters
by cross multiplication
= 11.2 liters x 2moles/ 0.500 moles = 44.8 liters
Answer:
See explanation
Explanation:
Temperature is defined as a measure of the average kinetic energy of the molecules of a body.
When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.
When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid
