Answer:
0.0423 L
Explanation:
Molarity can be represented by the following ratio:
Molarity = moles / volume (L)
You can plug the given values into the equation and simplify to find the volume.
Molarity = moles / volume
0.730 M = 0.0309 moles / volume
(0.730 M) x volume = 0.0309 moles
volume = 0.0423 L
Answer:
9.6 moles O2
Explanation:
I'll assume it is 345 grams, not gratis, of water. Hydrogen's molar mass is 1.01, not 101.
The molar mass of water is 18.0 grams/mole.
Therefore: (345g)/(18.0 g/mole) = 19.17 or 19.2 moles water (3 sig figs).
The balanced equation states that: 2H20 ⇒ 2H2 +02
It promises that we'll get 1 mole of oxygen for every 2 moles of H2O, a molar ratio of 1/2.
get (1 mole O2/2 moles H2O)*(19.2 moles H2O) or 9.6 moles O2
An ion is a charged particle that is formed when an atom gains electrons or an atom loses electrons.
First you need to know the definition of ion. An ion is a molecule or atom that has a positive or negative electrical charge. That is, an ion is an atom whose electric charge is not neutral. This charged particle can be positive or negative.
Ionization is the chemical or physical process by which ions are produced. In this process, negatively charged ions are produced by gaining electrons and are known as anions. The positively charged are produced by the loss of electrons and are known as cations.
In summary, an ion is a charged particle that is formed when an atom gains electrons or an atom loses electrons, and they are known as cations and anions respectively. The correct answer is both A and B.
In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.
