B. False
It was created in 1869
Answer:
2K + 2H₂O → 2KOH + H₂
Explanation:
The reactants are:
Potassium metal = K
Water = H₂O
The products are:
Potassium hydroxide = KOH
Hydrogen gas = H₂
The reaction equation is given as;
Reactants → Products
2K + 2H₂O → 2KOH + H₂
The reaction is a single displacement reaction
Idk sorry I just have to answer something or brainily won’t let me ask my question
Answer:
Explanation:
Symbol: K
Protons = 19
Electrons in an atom: 19
Neutrons: 39 - 19 = 20
Draw the nucleus at the center. Label it with 19 Protons and 20 Neutrons.
Draw a circle around the nucleus.
Put two dots opposite each other on the circle's circumference.
Draw another circle with its center at the nucleus bigger than you first circle.
Space 8 electrons around the circumference.
Draw a third circle like the other 2 only bigger.
Space 8 electrons around this circle's circumference.
Draw 1 more circle bigger than the third circle.
It has 1 electron.
