Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat.
If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
Nₐ=6.02*10²³ mol⁻¹
n(Na₂O)=0.5 mol
n(Na⁺)=2n(Na₂O)
N(Na⁺)=n(Na⁺)Nₐ=2n(Na₂O)Nₐ
N(Na⁺)=2*0.5*6.02*10²³=6.02*10²³ ions
Answer:
Decantation
Explanation:
Decantation is one of the process of separating mixture containing solid and liquid. In this process, gravity plays a very important role. The solid part of the mixture is allowed to settle down. The liquid is removed and separated in another container. It is a process that helps in the purification of the liquid. The particles that are insoluble settles down and is further subject to be separated from the mixture.
Answer: Your answer would be D. A neutral atom would become positively charged when they lose electrons because electrons are negatively charged. Removing some of these negative charges causes the atom to become more positively charged. Hope this has helped you :D
