V2 = 250 ml
Explanation:
Given:
P1 = 0.99 atm. V1 = 240 ml
P2 = 0.951 atm. V2 = ?
We can use Boyle's law to solve for V2
P1V1 = P2V2
V2 = (P1/P2)V1
= (0.99 atm/0.951 atm)(240 ml)
= 250. ml
Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
The term monomer refers to a unit made up of several atoms.This will make the correct answer B.
Answer:
The anode is oxidized and the cathode is reduced, in this way we are facing a redox reaction or oxide reduction.
Where the oxygenated compound oxidizes, and the protonized reduces.
Explanation:
When he says that oxygen is reduced the reaction would be:
OXYGEN + H (+1) -----> OH-
And the reaction where solid aluminum hydroxide is formed will be:
Al (+3) + 3 KOH (aqueous) -------> Al (OH) 3 (solid) + 3 K (+1),
Here we see how aluminum is immersed in an aqueous medium and becomes a solid compound in the form of hydroxide, where when attached to an oxygen, it is oxygenated and oxidized.
This reaction is considered irreversible
