Answer:
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
Explanation:
hope it's right
1. %yield = actual yield / theoretical yield x 100
= 3 g / 4. 46 g x 100
= 62.11 % percent yield
Hope This Helps! :3
The question is incomplete but i will try to offer as much help as i can.
Answer:
See explanation
Explanation:
The electron was discovered by J.J Thompson. His model of the atom was called the plum-pudding model of the atom.
He discovered that cathode rays being negatively charged particles were deflected by a magnet in just the same way as moving, negative electrically charged particles.
Similarly, in an electric field, they are deflected towards the positive plate of the electrostatic field which shows that they are negatively charged.
Answer
The base is Ba(OH)2
Explanation
This equation follows the path of, acid +base---salt +water
H2S +Ba(OH)2------BaS +2H2O
Where H2S is the acid, Ba(OH) is the base and 2H2O is water.
Here, Barium hydroxide reacts with hydrogen sulfide to give barium sulfide and water.
